GCOR Railroad Operating Rules Exam — Questions and Answers

Question 1: When must both switches of a hand-operated crossover be opened before starting a crossover movement?

Both switches must be opened before the movement starts. (Correct answer)
At all times, unless used for continuous switching by one crew.
Only when the movement is on a main track.
Only when the crossover connects to a siding.

Correct answer: Both switches must be opened before the movement starts.

GCOR Rule 8.12 requires that both switches of a crossover must be opened before a crossover movement starts. The movement must be completed before either switch is returned to its normal position. This ensures the route is completely lined and secured.

Question 2: Under GCOR, what information must be included in an emergency notification to the dispatcher after an accident?

Only the nature of the emergency
Train ID, location, nature of emergency, and any hazmat involved (Correct answer)
Train ID and location only
Train speed at time of incident and crew names

Correct answer: Train ID, location, nature of emergency, and any hazmat involved

GCOR requires emergency notifications to include the train identification, precise location, nature of the emergency, and identification of any hazardous materials involved.

Question 3: A yard crew is leaving a cut of cars unattended on a track. According to GCOR 7.6, what must be done to secure the equipment?

Verbal notification to the yardmaster is sufficient.
Only the automatic air brakes must be applied.
The cars must be coupled to a locomotive with its brakes set.
A sufficient number of hand brakes must be applied to prevent movement. (Correct answer)

Correct answer: A sufficient number of hand brakes must be applied to prevent movement.

GCOR Rule 7.6 states, 'Do not depend on air brakes to hold a train, engine, or cars in place when left unattended. Apply a sufficient number of hand brakes to prevent movement.' If hand brakes are inadequate, wheels must be blocked.

Question 4: When making a trailing point movement over a spring switch, which of the following is a primary requirement before proceeding?

A crew member must observe that the switch points are closed and fit properly. (Correct answer)
The train dispatcher must give verbal authorization for the movement.
The switch must be operated by hand to the reverse position and back again.
The movement must not exceed 5 MPH.

Correct answer: A crew member must observe that the switch points are closed and fit properly.

For a trailing point movement over a spring switch, the points are forced open by the wheels and then spring back. It is critical to ensure the points are properly closed before the movement starts to prevent a derailment. Testing the switch by hand (lining it over and back) is required only for certain facing point movements under specific signal indications.

Question 5: An electrically controlled lock that restricts the use of a hand-operated switch or derail is a:

Signal lock
Electric switch lock (Correct answer)
Manual lock
Dual control switch

Correct answer: Electric switch lock

Explanation: An electric switch lock is a type of lock that is controlled by electricity and is used to restrict the use of a hand-operated switch or derail. This means that the switch or derail can only be operated when the electric switch lock is unlocked or disengaged. The electric switch lock adds an extra layer of security and control to the operation of the switch or derail, ensuring that it can only be used when authorized.

Question 6: When a locomotive in a consist develops a mechanical failure that causes it to drag or resist movement, what action is required under GCOR?

Cut out the traction motors on the defective unit and continue
Reduce speed to 15 mph and proceed to the next siding
Stop the train and take the defective locomotive out of service (Correct answer)
Increase throttle on the remaining units to overcome the resistance

Correct answer: Stop the train and take the defective locomotive out of service

A locomotive that drags or resists movement creates a dangerous mechanical condition, requiring the train to stop and the defective unit to be removed from service.

Question 7: Under GCOR, what does a crew do when a train encounters an unexpected low-hanging obstruction over the track?

Contact the dispatcher and then proceed
Stop immediately and protect the obstruction before any action is taken (Correct answer)
Proceed at restricted speed while ducking
Reduce to 10 mph and proceed with caution

Correct answer: Stop immediately and protect the obstruction before any action is taken

GCOR requires the crew to stop immediately when an unexpected obstruction is encountered and protect the scene before taking further action.

Question 8: What action is required when a locomotive's dynamic brakes become inoperative during a descending grade operation?

Immediately apply emergency brakes and stop the train
Notify the dispatcher and use train brakes to control speed (Correct answer)
Tie down hand brakes on the rear cars and continue at slow speed
Increase locomotive throttle to maintain control

Correct answer: Notify the dispatcher and use train brakes to control speed

When dynamic brakes fail on a descending grade, the engineer must notify the dispatcher and rely on the train's air brakes to control speed.

Question 9: Under GCOR Rule 8.2, who is specifically assigned responsibility for the position of a hand-operated switch while it is in use?

The conductor of the train.
The engineer operating the locomotive.
The train dispatcher.
The employee operating the switch. (Correct answer)

Correct answer: The employee operating the switch.

GCOR Rule 8.2 clearly states, 'The employee operating the switch or derail is responsible for the position of the switch or derail in use.' This places direct responsibility on the individual physically manipulating the switch.

Question 10: When operating on another railroad, unless otherwise instructed, employees will be governed by:

All of the above (Correct answer)
The operating rules and timetable/special instructions of the railroad they are on
Air brake and train handling rules of the railroad they are employed by
Safety rules of the railroad they are employed by.

Correct answer: All of the above

Explanation: When operating on another railroad, employees will be governed by the safety rules, air brake and train handling rules, and the operating rules and timetable/special instructions of the railroad they are employed. All of these answers are correct because when working on another railroad, employees must follow the rules and regulations of that specific railroad in order to ensure safety and proper train operations.

Question 11: According to GCOR, what speed must be observed when passing a roadway worker's on-track equipment that has been given 'clear of the movement' notification?

10 mph
Normal timetable speed
20 mph (Correct answer)
Restricted speed

Correct answer: 20 mph

Even after on-track equipment has been cleared, GCOR requires trains to pass at no more than 20 mph to ensure worker safety.

Question 12: What are signal appliances that are interconnected so that each of their movements follows the other in a proper sequence?

Centralized traffic control
Track warrant signals
Interlocking (Correct answer)
Automatic block signal system

Correct answer: Interlocking

Explanation: Interlocking is the correct answer because it refers to a system of signal appliances that are interconnected in such a way that their movements follow each other in a proper sequence. This system ensures the safe and efficient movement of trains by preventing conflicting movements and maintaining a proper flow of traffic.

Question 13: A train crew hears the words "EMERGENCY, EMERGENCY, EMERGENCY" broadcast over the radio. According to GCOR, what is the required action for all other employees listening on that channel?

Acknowledge the transmission by saying "Roger Emergency."
Switch to a secondary channel to keep it clear for the emergency.
Give absolute priority to the communication and refrain from transmitting. (Correct answer)
Continue with normal duties but monitor the radio for instructions.

Correct answer: Give absolute priority to the communication and refrain from transmitting.

GCOR Rule 2.10 states that all employees must give absolute priority to an emergency communication. Unless they are directly involved in answering or assisting with the emergency, they must not transmit on the channel until they are certain no interference will result.

Question 14: A train is operating in CTC territory and stops at a control point with an absolute signal displaying 'Stop'. The crew needs to make a reverse movement just inside the block they came from to set out a car. According to GCOR, what is the first required action?

Wait for a more favorable signal indication before reversing.
Obtain permission from the control operator before making any reverse movement. (Correct answer)
Immediately begin the reverse movement at restricted speed, as it's within the same block.
Proceed through the stop signal, then initiate the reverse movement.

Correct answer: Obtain permission from the control operator before making any reverse movement.

GCOR Rule 6.4.2 states that if a movement stops while the trailing end is between the outer opposing absolute signals of a control point, it must not change direction without permission from the control operator. Since the train is at a control point, permission is mandatory before reversing, even if the movement is within the same signaled block.

Question 15: A train crew encounters a signal displaying a single red light. Under GCOR, what is the primary indication of this 'Stop' signal?

Proceed after stopping if the track ahead is seen to be clear.
Stop, then proceed at restricted speed after one minute.
Stop before any part of the train passes the signal and do not proceed without authority. (Correct answer)
Immediately reduce to restricted speed, but do not stop.

Correct answer: Stop before any part of the train passes the signal and do not proceed without authority.

A signal displaying a solid red light indicates 'Stop'. A train must stop before any part of it passes the signal mast. The train may not proceed until authorized by the control operator or as otherwise specified in the rules (e.g., under a track permit).

Question 16: A conductor is initiating a non-emergency radio call to the dispatcher. What is the correct format for the initial transmission?

"Dispatcher, this is train XYZ, over."
"(Railroad) Dispatcher from (Railroad) Train XYZ at MP 123, over." (Correct answer)
"This is XYZ conductor, need to talk to the dispatcher, over."
"Train XYZ to the dispatcher at Omaha, over."

Correct answer: "(Railroad) Dispatcher from (Railroad) Train XYZ at MP 123, over."

GCOR Rule 2.2, "Required Identification," specifies that transmissions must begin by identifying the party being called, followed by the calling party's own identification, which includes the railroad initials, train ID, and location. This ensures there is no confusion about who is talking to whom.

Question 17: According to GCOR, when must a locomotive's number plates or identification be legible?

Only during daylight operations
Only when the locomotive is in a designated reporting location
At all times while the locomotive is in service (Correct answer)

Correct answer: At all times while the locomotive is in service

Locomotive identification must be legible at all times while the unit is in service to allow proper identification for operational and safety purposes.

Question 18: A train crew is approaching established working limits. Under what condition may their train enter these limits?

If the train is moving at restricted speed.
After receiving permission from the train dispatcher.
If the governing signal to enter the limits displays a 'Proceed' indication.
Only after receiving direct instructions from the Roadway Worker in Charge (RWIC) controlling the limits. (Correct answer)

Correct answer: Only after receiving direct instructions from the Roadway Worker in Charge (RWIC) controlling the limits.

Working limits are under the exclusive control of the Roadway Worker in Charge (RWIC). Regardless of signal indication or dispatcher instructions for movement outside the limits, no train or on-track equipment may enter working limits without the express permission of the RWIC who is responsible for the on-track safety of the work group.

Question 19: When a train dispatcher transmits a mandatory directive by radio, what is the first action the copying employee must take after the dispatcher has finished speaking?

Acknowledge receipt by saying "Copy" or "Roger."
Immediately repeat the directive back to the dispatcher word-for-word. (Correct answer)
Write down the time and the dispatcher's name.
Ask the conductor to verify the contents of the directive.

Correct answer: Immediately repeat the directive back to the dispatcher word-for-word.

GCOR Rule 2.3, "Repetition," requires that employees who receive transmissions containing information, instructions, or advice that could affect safety must repeat them back to the sender. This ensures the directive was copied and understood correctly before being acted upon.

Question 20: A train is authorized to enter the main track in CTC territory at a hand-operated switch where no governing signal exists. What must happen before the train occupies the main track?

The crew must open the switch and wait 5 minutes to establish signal protection.
The control operator must verbally authorize the train to enter the track. (Correct answer)
The train can enter immediately after lining the switch, then report to the dispatcher.
The crew must provide flag protection in both directions.

Correct answer: The control operator must verbally authorize the train to enter the track.

According to GCOR Rule 9.17, within CTC territory, before a train enters the track at a hand-operated switch with no governing signal, the control operator must authorize the movement. The control operator is responsible for verifying there are no conflicting movements before granting this authority.

Question 21: When is the mandatory verbal repetition of a track warrant by the copying employee NOT required according to GCOR?

During emergency situations as declared by the railroad.
If the warrant only authorizes movement for less than one mile.
When the employee has a certified conductor's license.
When the track warrant is transmitted mechanically to a device. (Correct answer)

Correct answer: When the track warrant is transmitted mechanically to a device.

GCOR Rule 14.13 states that repetition is not required when track warrants are transmitted mechanically (e.g., to a computer or fax machine in the cab). In this case, the 'OK' time is given when the warrant is issued, and the standard read-back procedure is bypassed.

Question 22: Employees must not have any measurable alcohol in their breath or in their bodily fluids:

When reporting for duty
While on company property
All of the above (Correct answer)
While on duty

Correct answer: All of the above

Explanation: Employees must not have any measurable alcohol in their breath or bodily fluids while on duty when reporting for duty, or while on company property. This means that regardless of the specific situation, employees are prohibited from having any detectable alcohol in their system. This policy ensures that employees are fit for work and able to perform their duties safely and effectively.

Question 23: According to GCOR, what action must be taken before a train passes over a track that has been reported as suspected of having a defect?

Stop and inspect the track before proceeding
Obtain specific authority from the dispatcher or track authority (Correct answer)
Reduce speed to 10 mph and proceed
Proceed at restricted speed

Correct answer: Obtain specific authority from the dispatcher or track authority

GCOR requires specific authority from the dispatcher or track authority before a train proceeds over track suspected of having a defect.

A speed not exceeding 10 mph at all times
A speed that allows stopping within half the range of vision, not to exceed 20 mph
A speed not exceeding 20 mph

Correct answer: A speed that allows stopping within the range of vision, not to exceed 15 mph

Restricted speed under GCOR means a speed that allows the train to stop within the range of vision, and in no case exceeding 15 mph.

Question 31: Under what specific condition may a train dispatcher issue a track warrant to a train that will have overlapping limits with men or equipment?

Never, it is strictly prohibited to have overlapping limits between a train and men or equipment.
If the train crew verbally agrees to look out for the men and equipment.
Only if the men or equipment are also operating a train.
When all trains authorized are notified and instructed to move at restricted speed within the overlapping limits. (Correct answer)

Correct answer: When all trains authorized are notified and instructed to move at restricted speed within the overlapping limits.

GCOR Rule 14.5 allows for a track warrant to be issued with overlapping limits for a train and men or equipment, provided that all trains involved are notified of the men or equipment and are instructed to move at restricted speed through the shared limits. The rule also requires that the employee in charge of the men or equipment is informed about the trains.

Question 32: When determining a 'sufficient' number of hand brakes to apply on unattended equipment, which of the following set of factors must be considered?

The track grade, weather conditions, and tonnage of the cars. (Correct answer)
The proximity to the nearest yard and the type of locomotive used.
The time of day and the number of crew members present.
The schedule of the next train to use the track.

Correct answer: The track grade, weather conditions, and tonnage of the cars.

GCOR requires a performance-based approach to securing equipment. Employees must evaluate conditions that could cause movement, such as the steepness of the track (grade), wind (weather), and the weight of the cars (tonnage), to determine how many hand brakes are sufficient to hold the equipment safely.

Question 33: An employee is instructed by a supervisor to perform an action that they, in good faith, believe violates a safety rule and could cause injury. What is the employee's right and responsibility in this situation?

To report the supervisor to an outside agency immediately.
To obey the supervisor's order without question.
To challenge the directive in good faith. (Correct answer)
To refuse the directive and walk off the job.

Correct answer: To challenge the directive in good faith.

GCOR includes provisions for a 'Good Faith Challenge' (Rule 1.4.1). This allows an employee to challenge a directive they believe would violate a safety rule without fear of reprisal, ensuring that safety is not compromised by a direct order.

Question 34: Under GCOR, when a train is operating in a dark territory, what is the maximum speed permitted when approaching a switch that is not within a signaled territory?

The train must obtain verbal authority before passing the switch
The train must stop 1,500 feet from the switch

Correct answer: Stop before entering the limits unless instructed otherwise by the employee in charge.

GCOR Rule 15.2, 'Protection by Track Bulletin Form B,' requires that a train must not enter the limits protected by a Form B bulletin until instructed by the employee in charge. A train must stop before the limits unless prior instructions are received.

Question 49: Under GCOR, after a train is involved in a collision, when may the crew move the equipment without specific authority?

Only if movement is necessary to protect life or prevent further damage (Correct answer)
After a 30-minute waiting period
Immediately to clear the main track
Only with written authority from the chief dispatcher

Correct answer: Only if movement is necessary to protect life or prevent further damage

GCOR only permits movement of collision-involved equipment without specific authority when such movement is necessary to protect human life or prevent additional damage.

Question 50: A Roadway Worker in Charge (RWIC) is establishing 'Foul Time' on a controlled track. Before the foul time becomes effective, what communication must occur between the RWIC and the train dispatcher?

The RWIC must state their name, location, and the number of workers in their group.
The train dispatcher must provide a unique authorization number to the RWIC.
The RWIC must confirm that all workers are wearing high-visibility personal protective equipment.
The RWIC must repeat the track identifier, limits, and time of the foul time back to the dispatcher for verification. (Correct answer)

Correct answer: The RWIC must repeat the track identifier, limits, and time of the foul time back to the dispatcher for verification.

According to federal regulations (49 CFR § 214.323) which GCOR incorporates, before foul time becomes effective, the roadway worker in charge must repeat the track number/identifier, the specific track limits, and the time limits back to the issuing train dispatcher or control operator. This ensures mutual understanding and that the correct protection is being established.

Question 51: What is a controlled siding?

A siding within CTC or interlocking limits where hand signals authorize the siding's use
A siding within CTC or interlocking limits where electric lock switches authorize the siding's use
A siding within CTC where a distant signal indication authorizes the siding use
A siding within CTC or interlocking limits where a signal indication authorizes the siding's use (Correct answer)

Correct answer: A siding within CTC or interlocking limits where a signal indication authorizes the siding's use

Explanation: A controlled siding refers to a siding within CTC or interlocking limits where a signal indication is required to authorize the use of the siding. This means that train operators must receive a specific signal indication before using the siding, ensuring the safe and controlled movement of trains on the tracks.

Question 52: A train has authority on a track warrant from MP 10 to MP 30. After the entire train passes MP 20, the conductor reports this to the train dispatcher. What is the status of the train's authority?

The authority is considered void up to MP 20. (Correct answer)
The authority is now void between MP 20 and MP 30.
A new track warrant is required to proceed to MP 30.
The entire warrant from MP 10 to MP 30 remains in effect.

Correct answer: The authority is considered void up to MP 20.

GCOR Rule 14.3 states that when a crew member informs the train dispatcher that the entire train has passed a specific point, the track warrant authority is considered void up to that point. The authority from MP 20 to MP 30 remains in effect.

Question 53: An employee notices a defective section of track that could potentially affect safe train operations. Under GCOR rules for reporting unusual conditions, what is the employee's IMMEDIATE responsibility?

Wait until the end of the shift to file a written report.
Only report it if a train is currently approaching the defect.
Report it by the first available means of communication. (Correct answer)
Fix the defect personally if the tools are available.

Correct answer: Report it by the first available means of communication.

GCOR Rule 1.1.3 mandates that employees must 'Report by the first means of communication any... defects in tracks, bridges, or signals; or any unusual condition that may affect the safe and efficient operation of the railroad.' This ensures that potential hazards are addressed as quickly as possible.

Question 54: According to GCOR, when must a crew report a rough or unusual track condition observed during their run?

Only if another train reports the same condition
Only if it caused a speed reduction
At the end of the trip in the trip report
Immediately to the dispatcher upon observation (Correct answer)

Correct answer: Immediately to the dispatcher upon observation

GCOR requires crews to report rough or unusual track conditions to the dispatcher immediately upon observation, not at the end of the trip.

Question 55: Which of the following is a key difference between movement authority in an Automatic Block System (ABS) territory versus a Centralized Traffic Control (CTC) territory?

CTC territory does not use intermediate signals, only absolute signals.
In CTC, signal indications authorize train movement, while in ABS, signals provide protection but do not authorize movement. (Correct answer)
Reverse movements are not permitted in ABS territory.
In ABS, trains can proceed without any form of track authority.

Correct answer: In CTC, signal indications authorize train movement, while in ABS, signals provide protection but do not authorize movement.

In CTC territory, block signal indications are the primary method used to authorize train movements. In ABS territory, signals provide information about block occupancy to ensure trains are spaced safely, but the authority to occupy the main track comes from another source, such as a track warrant or timetable authority.

Question 56: Under what circumstance is a train permitted to enter CTC territory without a proceed indication on a controlled signal?

When entering from a yard track where Yard Limits are in effect.
If the train is a light engine movement.
When the control operator grants verbal authority to pass a Stop indication or to enter the track between signals. (Correct answer)
During a signal suspension, all trains may enter CTC at restricted speed without authorization.

Correct answer: When the control operator grants verbal authority to pass a Stop indication or to enter the track between signals.

GCOR Rule 10.1 specifies that a train must not enter or occupy any track where CTC is in effect unless a controlled signal displays a proceed indication OR the control operator authorizes the movement. This authorization can be to pass a stop signal or to enter the track between signals.

Question 57: What is the most important element in performing duties?

Cooperation with fellow employees
Safety (Correct answer)
Reporting for duty at the proper place and time
None of the above

Correct answer: Safety

Safety measures include following protocols, using protective equipment, and being aware of potential hazards. By prioritizing safety, individuals can effectively carry out their duties without compromising their own health and the safety of others.

Question 58: Under GCOR, what action is required when a crew member becomes incapacitated and unable to perform their duties?

The remaining crew member must stop the train and notify the dispatcher (Correct answer)
The train must continue to maintain schedule while help is summoned
The incapacitated member must be removed at the next crossing
The remaining crew may continue to the next stop if less than 10 miles away

Correct answer: The remaining crew member must stop the train and notify the dispatcher

GCOR requires the remaining crew member to stop the train and immediately notify the dispatcher when a crew member becomes incapacitated.

Question 59: The location of absolute signals controlled by a control operator is a:

Control Operator
Control approach
Control point (Correct answer)
Control location

Correct answer: Control point

Explanation: The location of absolute signals controlled by a control operator is referred to as a control point. This is the designated area where the control operator is stationed to manage and control the absolute signals. It serves as a central point from where the control operator can monitor and regulate the signals to ensure smooth and safe traffic flow.

Question 60: When a locomotive is placed in multiple unit (MU) service, which locomotive's controls govern the train's braking?

The lead locomotive from which the engineer operates (Correct answer)
The rear locomotive, which acts as the primary retarding unit
Any locomotive in the consist, as all are interconnected
The locomotive with the highest horsepower rating

Correct answer: The lead locomotive from which the engineer operates

In multiple unit service, the lead locomotive from which the engineer operates provides the controlling inputs for braking and throttle for the entire consist.

The conductor must authorize continued use and document the defect
The locomotive may continue if the independent brake is functional
The locomotive may move at restricted speed only
The locomotive must be set out and not used until repaired (Correct answer)

Correct answer: The locomotive must be set out and not used until repaired

A locomotive with a failed automatic brake must be set out of service and not used until the defect is repaired.

Question 62: A train crew is preparing for a switching operation in a complex yard. Before beginning the work, what critical safety activity must they perform together?

Review the latest stock market report.
Conduct a job briefing to discuss the plan and potential hazards. (Correct answer)
Check the locomotive's fuel level.
Ensure the lead locomotive has been recently washed.

Correct answer: Conduct a job briefing to discuss the plan and potential hazards.

Conducting a job briefing is a fundamental safety practice. It ensures all crew members understand the planned movements, their individual responsibilities, and any potential hazards involved in the task, which is essential for safe and coordinated work.

Question 63: A train crew has been granted 'Track and Time' authority from MP 80 to MP 90 in CTC territory. Within these limits is CP 85, which is a dispatcher-controlled crossover. How does this authority affect their movement at CP 85?

The 'Track and Time' authority does not include interlocking limits, so they cannot enter CP 85.
They may pass the signal only after stopping and waiting 10 minutes.
They may pass the absolute signal at CP 85 displaying a 'Stop' indication without stopping and without communicating with the control operator. (Correct answer)
They must stop before the absolute signal at CP 85 and get separate permission to pass it.

Correct answer: They may pass the absolute signal at CP 85 displaying a 'Stop' indication without stopping and without communicating with the control operator.

GCOR Rule 10.3 (Track and Time) grants authority to occupy the track within specified limits. Unless a control point is specifically designated as a manual interlocking in the timetable, the Track and Time authority includes the limits of the control point. Therefore, a train can pass a controlled signal displaying 'Stop' within their Track and Time limits without stopping or obtaining additional permission.

Question 64: Under GCOR, what must the engineer do when the locomotive alerter (vigilance device) sounds its warning?

Acknowledge the device by pressing the designated button or pedal (Correct answer)
Apply the emergency brake immediately
Radio the dispatcher to report the alert condition
Reduce speed to restricted speed until the alert clears

Correct answer: Acknowledge the device by pressing the designated button or pedal

The engineer must acknowledge the alerter by pressing the designated acknowledgment button or pedal to confirm they are alert and in control.

Question 65: Under which circumstance must a train crew receive a new track warrant to alter their existing limits?

When they report clear of a portion of their limits.
When they are delayed within their limits.
When the dispatcher verbally advises a change.
When the limits or instructions of the original warrant need to be changed. (Correct answer)

Correct answer: When the limits or instructions of the original warrant need to be changed.

According to GCOR Rule 14.11, 'Changing Track Warrants,' if the limits or instructions of a track warrant need to be changed, a new track warrant must be issued that voids the previous one. Employees are explicitly forbidden from altering a warrant in any other manner.

Question 66: When a GCOR train must stop and the engineer cannot stop within half the range of vision, what action is required?

Stop immediately regardless of consequences
Sound the horn and proceed at 10 mph
Apply emergency brakes and sound the horn (Correct answer)
Reduce speed and call the dispatcher

Correct answer: Apply emergency brakes and sound the horn

When unable to stop within half the range of vision, GCOR requires the engineer to apply emergency brakes and sound the horn to warn others.

Question 67: Which of the following actions is explicitly prohibited when a blue signal is displayed on a track, according to GCOR 5.13?

Using a radio to communicate near the protected track.
Walking on the ballast within 10 feet of the protected track.
Placing other rolling equipment on the same track in a way that blocks the view of the blue signal. (Correct answer)
Operating a switch that provides access to the protected track.

Correct answer: Placing other rolling equipment on the same track in a way that blocks the view of the blue signal.

GCOR Rule 5.13 states that a blue signal signifies workmen are on, under, or between rolling equipment. One of the key requirements is that 'Other rolling equipment must not be placed on the same track so as to block or reduce the view of the blue signal.'

Question 68: Under GCOR, what speed restriction applies to a train with defective or inoperative dynamic brakes on grades exceeding a specific percentage?

The train must not exceed the speed authorized by the chief mechanical officer or equivalent (Correct answer)
The train must stop and not proceed until repaired
No restriction applies if air brakes are functional
The train must not exceed 30 mph on any grade

Correct answer: The train must not exceed the speed authorized by the chief mechanical officer or equivalent

GCOR requires that when dynamic brakes are defective on steep grades, the speed must not exceed what is authorized by the designated mechanical authority.

Question 69: A notice of conditions affecting train movement is:

A train ledger
A train lineup
A track bulletin (Correct answer)
A train location manual

Correct answer: A track bulletin

Explanation: A track bulletin is a notice that provides information about conditions that may affect train movement. It includes details about track maintenance, repairs, or any other factors that could impact the schedule or safety of train operations. Train personnel rely on track bulletins to stay informed and make necessary adjustments to ensure smooth and efficient train movement. A train ledger, train location manual, and train lineup are not specifically related to providing information about conditions affecting train movement, making them incorrect options.

Question 70: According to GCOR, when a crew member observes fire on the train, what is the immediate required action?

Stop the train, protect the movement, and notify the dispatcher while evacuating if necessary (Correct answer)
Stop the train immediately and fight the fire with onboard extinguishers

Following orders
Punctuality
Safety (Correct answer)
Efficiency

Correct answer: Safety

GCOR Rule 1.1 explicitly states, 'Safety is the most important element in performing duties. Obeying the rules is essential to job safety and continued employment.' This establishes safety as the primary concern above all other aspects of work.

Question 72: An engineer finishes a radio conversation with the dispatcher and no further response is expected. Which procedural word should the engineer use to end the final transmission?

Over and Out
Over
Roger
Out (Correct answer)

Correct answer: Out

According to GCOR Rule 2.5, the word "OUT" is used to signify that the communication is complete and no response is expected. "Over" is used when a response is expected. The phrase "Over and Out" is contradictory and incorrect procedure.

Question 73: A train is authorized to pass a signal displaying a 'Restricting' indication. Which of the following is a key requirement for the train's movement?

The crew must contact the dispatcher every mile.
The movement must be able to stop within half the range of vision, short of any obstruction, and not exceeding 20 MPH. (Correct answer)
The train must not exceed 10 MPH.
The train may proceed at normal speed if the next signal is visible and clear.

Correct answer: The movement must be able to stop within half the range of vision, short of any obstruction, and not exceeding 20 MPH.

A 'Restricting' indication requires movement at restricted speed. GCOR defines restricted speed as a speed that allows stopping within one-half the range of vision, short of a train, engine, railroad car, stop signal, misaligned switch, or broken rail, not to exceed 20 MPH.

Question 74: What is a crossover?

A track connection between two adjacent sidings
A combination of two switches that connect two adjacent tracks (Correct answer)
A track connection between two or more adjacent dual control switches
A combination of two switches that connect two adjacent trains

Correct answer: A combination of two switches that connect two adjacent tracks

Explanation: A crossover refers to a combination of two switches that connect two adjacent tracks. This allows trains to move from one track to another, typically in opposite directions. By using the crossover, trains can change tracks without having to reverse or make a large detour. This helps to improve efficiency and flexibility in the railway system.

Question 75: When must the conductor inform the engineer of a restriction?

After the train passes two stations in advance of the restriction, but at least after the train passes the last station
When leaving the initial station
Anytime it's convenient, but must be done at least 1 mile from the restriction.
After the train passes the last station, but at least 2 miles from the restriction. (Correct answer)

Correct answer: After the train passes the last station, but at least 2 miles from the restriction.

Explanation: The conductor must inform the engineer of a restriction after the train passes the last station, but at least 2 miles from the restriction. This ensures that the engineer has enough time to prepare for the restriction and adjust the train's speed accordingly. Informing the engineer earlier than 2 miles from the restriction may not provide enough time for the necessary adjustments to be made.

Question 76: A single locomotive is being left unattended on a main track. What is the minimum hand brake requirement according to GCOR?

The automatic air brake is sufficient if the compressor is running.
One wheel must be chocked.
Permission must be received from the dispatcher to leave it without a hand brake.
The hand brake on the locomotive must be fully applied. (Correct answer)

Correct answer: The hand brake on the locomotive must be fully applied.

When leaving locomotives unattended, all locomotives in the consist must be secured with a handbrake. This is a specific requirement to ensure the power units themselves are secured against unintended movement.

Question 77: According to GCOR, if a train experiences a runaway condition on a descending grade, what is the required action?

Alert the dispatcher and attempt to reach a siding
Reduce throttle to idle and rely on dynamic brakes
Apply emergency brakes, sound the horn continuously, and notify the dispatcher immediately (Correct answer)

Possessing an alcoholic beverage. (Correct answer)
Using a company-supplied electronic device for work purposes.
Consuming a caffeinated beverage.

Correct answer: Possessing an alcoholic beverage.

GCOR Rule 1.5 is clear: 'The use or possession of alcoholic beverages while on duty or on company property is prohibited.' While rules exist for medication and electronic devices, the outright possession of alcohol is forbidden.

Question 79: If an employee receives a radio communication that is incomplete or not understood, what action must be taken?

Act on the portion of the message that was clearly understood.
Ask another crew member for their interpretation of the message.
Wait five seconds and if there is no clarification, proceed as planned.
Treat the communication as if it was not sent and do not act upon it. (Correct answer)

Correct answer: Treat the communication as if it was not sent and do not act upon it.

GCOR Rule 2.6, "Communication Not Understood or Incomplete," states that an employee must not act upon a communication that is not fully understood. They must treat it as if it were not sent. The only exception is if the information suggests a safety hazard, in which case the employee must take the safe course, including stopping movement until clarification is received.

Question 80: Under GCOR, who is responsible for the safe and efficient operation of the locomotive consist?

The conductor, as the employee in charge of the train
The train dispatcher, who controls all movements
Both the engineer and conductor share equal responsibility (Correct answer)

Correct answer: Both the engineer and conductor share equal responsibility

Under GCOR, both the engineer and conductor share responsibility for the safe and efficient operation of the train and locomotive consist.

Question 81: Which of the following is the correct procedure for voiding a track warrant that is no longer needed or must be changed?

The warrant automatically becomes void after a fixed period of two hours.
A new track warrant must be issued that includes the instruction 'Track Warrant No. ___ is void'. (Correct answer)
The crew can verbally agree with the dispatcher to void the warrant.
The crew simply writes 'VOID' on their copy; no communication with the dispatcher is needed.

Correct answer: A new track warrant must be issued that includes the instruction 'Track Warrant No. ___ is void'.

GCOR Rule 14.11 specifies that to change the limits or instructions of a track warrant, a new warrant must be issued. This new warrant must explicitly state, 'Track Warrant NO. ____________ is void,' followed by the number of the warrant being superseded.

Question 82: Under GCOR, what must a crew do when operating on a track where the speed limit is reduced due to a slow order and the slow order location is not clearly marked?

Reduce speed before reaching the slow order location to ensure compliance (Correct answer)
Contact the dispatcher for exact milepost location
Estimate the location and begin reduction 500 feet early
Proceed at normal speed until the track condition is observed

Correct answer: Reduce speed before reaching the slow order location to ensure compliance

GCOR requires crews to reduce speed in advance of the slow order location to ensure the train is at the restricted speed when it reaches that point.

Question 83: What is a dual-control switch?

A power-operated switch, moveable point frog, or derail that can also be operated by hand (Correct answer)
A hand-operated switch that has dual levers
Two switches controlling the same track
Electric switch

Correct answer: A power-operated switch, moveable point frog, or derail that can also be operated by hand

Explanation: A dual control switch is a power-operated switch, moveable point frog, or derail that can also be operated by hand. This means that it can be controlled both automatically and manually, providing flexibility in its operation.

Question 84: Which of the following is required before making a reverse movement on a main track?

The conductor must walk ahead to protect the movement.
The headlight must be set to dim and flashing.
Permission must be obtained from the train dispatcher or control operator, unless within the same signaled block. (Correct answer)
The movement must be made at timetable speed.

Correct answer: Permission must be obtained from the train dispatcher or control operator, unless within the same signaled block.

GCOR Rule 6.4.1, 'Permission for Reverse Movements,' mandates that a train must obtain permission from the train dispatcher or control operator before making a reverse movement on a main track, with the exception of movements staying within the same signaled block in certain territories like CTC.

Question 85: A train crew is preparing to couple to a stationary cut of cars. What is the maximum permissible coupling speed according to GCOR 7.4?

A speed that permits stopping within half the range of vision.
Restricted Speed
4 MPH (Correct answer)

Notify the train dispatcher of the switch's current position.
Line and lock the switch for the main track. (Correct answer)
Place a red flag at the switch stand to indicate it was used.
Leave the switch lined for the track last used.

Correct answer: Line and lock the switch for the main track.

GCOR Rule 8.3 states that the normal position of a main track switch is for main track movement and it must be lined and locked in that position after use, unless specific exceptions apply (such as being attended or under dispatcher authority).

Question 87: A train crew receives a track warrant that includes the instruction in Box 8: 'Hold main track at last named point.' If the last named point is a station with a siding, what does this instruction require?

The train's authority extends to and includes the last siding switch.
The train may proceed through the station on the main track without stopping.
The train's authority extends to but does not include the last siding switch. (Correct answer)
The train must stop before the first siding switch at the station.

Correct answer: The train's authority extends to but does not include the last siding switch.

According to GCOR Rule 14.2 (B), when a track warrant includes the instruction 'Hold main track at last named point,' the train's authority extends up to, but does not include, the last siding switch at that location. This prevents the train from fouling the switch that an opposing train might need to use.

Question 88: Before operating a locomotive, what must crew members do according to GCOR requirements?

Sign a daily release form confirming the locomotive is fit for service
Test the locomotive at full throttle for a minimum of five minutes
Obtain written permission from the dispatcher before boarding
Inspect the locomotive and report any defects to the proper authority (Correct answer)

Correct answer: Inspect the locomotive and report any defects to the proper authority

GCOR requires crew members to inspect the locomotive before operation and report any defects to the proper authority to ensure safe operation.

Question 89: According to GCOR, what must a crew do upon discovering a broken rail?

Reduce speed to 10 mph and proceed across the break
Stop and flag any following trains, then await dispatcher instructions
Proceed slowly over the broken rail to maintain schedule
Stop immediately, protect both ends of the break, and notify the dispatcher (Correct answer)

Correct answer: Stop immediately, protect both ends of the break, and notify the dispatcher

GCOR requires the crew to stop immediately upon discovering a broken rail, protect both ends of the break, and notify the dispatcher before any other trains approach.

Question 90: A train is operating within Yard Limits. What is the primary method of authorizing movement on the main track within these limits?

Verbal permission from the yardmaster.
The presence of a 'Yard Limit' sign itself serves as authority. (Correct answer)
A track warrant issued by the dispatcher.
A clear signal indication from a block signal.

Correct answer: The presence of a 'Yard Limit' sign itself serves as authority.

GCOR Rule 6.13, 'Yard Limits,' states that within yard limits, trains or engines are authorized to use the main track not protecting against other trains or engines. The rule itself, indicated by timetable and signs, provides the authority, with the key stipulation that all movements must be made at restricted speed.

Question 91: Under GCOR, when must an engineer reduce speed to 20 mph or less at grade crossings not equipped with automatic warning devices?

Only in inclement weather
Only at night
Only when flagged by a crew member
Always, regardless of visibility (Correct answer)

Correct answer: Always, regardless of visibility

GCOR requires trains to reduce to 20 mph or less at all passive grade crossings (those without automatic warning devices) regardless of conditions.

Question 92: A roadway work group is protected by a watchman/lookout providing 'Train Approach Warning'. What is the primary responsibility of each roadway worker when the watchman/lookout gives a warning of an approaching train?

To acknowledge the warning by raising a hand signal to the watchman.
To move to a predetermined place of safety and remain there until the train has passed. (Correct answer)
To secure all tools and equipment before leaving the track.
To immediately contact the RWIC for further instructions.

Correct answer: To move to a predetermined place of safety and remain there until the train has passed.

When 'Train Approach Warning' is the method of protection, the system relies on the watchman/lookout providing timely warning and each worker immediately occupying a predetermined place of safety. The first and most critical action is to clear the track to the place of safety. Other actions are secondary to ensuring personal safety from the approaching train.

Question 93: An absolute signal is:

A block or interlocking signal without a number plate. (Correct answer)
A block or interlocking signal with a number plate.
Any signal displaying a red aspect.
A signal with a number plate.

Correct answer: A block or interlocking signal without a number plate.

Explanation: An absolute signal refers to a block or interlocking signal that does not have a number plate. This means that it does not display any specific information or indication, but rather serves as a general signal without any additional instructions. It is important to differentiate absolute signals from other types of signals that may display a red aspect or have a number plate, as they have different meanings and implications for train operations.

Question 94: According to GCOR, when must the locomotive horn be sounded at a public grade crossing?

At all times when the locomotive is moving through a crossing
Only during nighttime operations or in poor visibility conditions
Only when active warning devices are not functioning
At approximately one-quarter mile before the crossing and until the locomotive occupies the crossing (Correct answer)

Correct answer: At approximately one-quarter mile before the crossing and until the locomotive occupies the crossing

GCOR requires the horn to be sounded beginning approximately one-quarter mile before a public grade crossing and continuing until the locomotive occupies the crossing.

Question 95: A train receives a track warrant with Box 7 checked: 'Not in effect until after the arrival of Train XYZ at Dover.' What action must the crew take?

Depart immediately and clear the main track before Train XYZ arrives.
Proceed at restricted speed until Train XYZ is met.
Must not act on their authority until they have confirmed Train XYZ has arrived at Dover. (Correct answer)
Contact the dispatcher for verbal permission to depart.

Correct answer: Must not act on their authority until they have confirmed Train XYZ has arrived at Dover.

A track warrant with Box 7 checked creates a conditional authority. The authority granted by the warrant cannot be used, and the train cannot enter the limits, until the specified train (Train XYZ) has arrived at the designated location (Dover). This is a common method for arranging meets between trains in TWC territory.

Question 96: A train is authorized to enter a yard track protected by a derail. Before the train occupies the track, what must be done with the derail?

The train must stop and wait for a five-minute interval before proceeding.
The train dispatcher must be contacted for verbal permission to pass the derail.
The derail must be removed from the rail or placed in the non-derailing position. (Correct answer)
The derail must be inspected and confirmed to be in the derailing position.

Correct answer: The derail must be removed from the rail or placed in the non-derailing position.

The purpose of a derail is to protect another track (often the main track) from an unauthorized movement. The derail must be placed in the non-derailing position to allow equipment to safely enter the track it protects.

Question 97: Your train is approaching an interlocking and the governing signal displays a red over green aspect. What action should you take?

Stop immediately; the signal is improperly displayed.
Proceed at normal speed as the route is clear.
Proceed prepared to stop at the next signal.
Proceed on the diverging route at the prescribed speed through the turnout. (Correct answer)

Correct answer: Proceed on the diverging route at the prescribed speed through the turnout.

A red over green aspect is a 'Diverging Clear' signal. It indicates that the route is lined for a diverging movement and the train may proceed through the turnout at the speed specified in the timetable or special instructions. The track beyond the interlocking is clear.

Question 98: Under GCOR, what must be done before a train movement resumes following an emergency stop?

The conductor must walk the entire train
The dispatcher must be notified and a release must be received
An inspection must be made and the cause of the emergency must be determined (Correct answer)

Correct answer: The locomotive must be inspected and the brakes released by a qualified employee

Before moving a locomotive that has been set out, a qualified employee must inspect it and ensure the brakes are properly released.

Question 101: When a locomotive must be operated cab-forward (long hood forward), what additional precaution does GCOR require?

The dispatcher must be notified and movement limited to yard tracks only
Speed must be reduced to no more than 10 mph at all times
The headlight on the leading end must be illuminated (Correct answer)
A qualified crew member must be posted as a lookout at the leading end

Correct answer: The headlight on the leading end must be illuminated

When a locomotive is operated long hood or cab forward, the headlight on the leading end must be illuminated to provide visibility and warning to others.

Question 102: A train has been given authority to proceed on a main track where a block system is in effect. If the train stops or its speed is reduced below 10 MPH after passing a proceed signal, what action is required by GCOR Rule 9.9?

Wait for a following train to pass before proceeding.
Reverse to the last signal and get a new indication.
Contact the dispatcher immediately for new instructions.
Proceed at restricted speed until the next signal is visible and displays a proceed indication. (Correct answer)

Correct answer: Proceed at restricted speed until the next signal is visible and displays a proceed indication.

GCOR Rule 9.9, 'Train Delayed Within a Block,' specifies that if a train that entered a block on a proceed indication stops or slows below 10 MPH, it must then proceed at restricted speed until the next signal is visible and that signal displays a proceed indication.
