Questions and Answers
  • 1. 

    What is required to operate in DCS territory?

    • A.

      Verbal permission of the Dispatcher

    • B.

      Form D Line 2

    • C.

      Form D Line 6

    • D.

      Form D Line 13

    Correct Answer
    B. Form D Line 2
    Explanation
    To operate in DCS territory, the required document is Form D Line 2. This form is necessary to indicate the train's authority and permission to operate within the DCS territory. It serves as a communication tool between the train crew and the dispatcher, ensuring that the train is aware of the specific instructions and restrictions in place for that territory. Without Form D Line 2, the train may not have the necessary authorization to operate in DCS territory.

    Rate this question:

  • 2. 

    A hand-operated switch maybe used as a location for he beginning or end of Line 2 authority. 

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A hand-operated switch can be used as a location for the beginning or end of Line 2 authority. This means that the switch can be manually operated to control the flow of trains on Line 2, either starting or ending their authority to proceed. This suggests that the switch is an important control point in managing the movement of trains on Line 2.

    Rate this question:

  • 3. 

    If Line 2 authority ends at an Interlocking, where exactly does the authority end?

    • A.

      Distant signal

    • B.

      Controlled Point Signal

    • C.

      Home Signal

    • D.

      Interlocking Signal

    Correct Answer
    C. Home Signal
    Explanation
    The authority ends at the Home Signal. Home Signals are located at the entrance of a block section and indicate whether the track ahead is clear or occupied. They are typically controlled by the signal operator and are used to regulate the movement of trains. Once a train passes the Home Signal, it enters the block section and the authority for that train ends.

    Rate this question:

  • 4. 

    When entering DCS territory at a hand-operated switch, in order to travel the opposite direction, how far beyond the switch is the movement allowed?

    • A.

      1 train length

    • B.

      To the next signal

    • C.

      This movement is not allowed

    • D.

      None of the above 

    Correct Answer
    A. 1 train length
    Explanation
    When entering DCS territory at a hand-operated switch, the movement is allowed up to 1 train length beyond the switch in order to travel in the opposite direction. This means that the train can proceed beyond the switch until it has cleared a distance equal to the length of one train.

    Rate this question:

  • 5. 

    The maximum authorize speed for passenger trains within non-signaled DCS territory is ________.

    Correct Answer
    59mph
    Explanation
    The maximum authorized speed for passenger trains within non-signaled DCS territory is 59mph. This means that passenger trains are allowed to travel at a maximum speed of 59 miles per hour in areas where there are no signals or indications to control their speed. This speed limit ensures the safety of both the passengers and the train by preventing excessive speed and allowing enough time for the train to stop or react to any potential obstacles or hazards on the track.

    Rate this question:

  • 6. 

    If approaching a home signal at the beginning of ABS territory, with a distant signal not in service, how must the train approach the home signal?

    • A.

      Restricted Speed

    • B.

      Slow Speed

    • C.

      Restricted Speed not exceeding 15mph

    • D.

      Prepared to stop

    Correct Answer
    D. Prepared to stop
    Explanation
    When approaching a home signal at the beginning of ABS territory, if the distant signal is not in service, the train must approach the home signal prepared to stop. This means that the train should be ready to come to a complete halt if necessary. It indicates that there may be a potential obstruction or danger ahead, and the train must be prepared to stop to ensure safety.

    Rate this question:

  • 7. 

    After a train has reached the limits of it's Line 2 authority, the Line 2 authority is ________.

    Correct Answer
    fulfilled
    Explanation
    After a train has reached the limits of its Line 2 authority, the Line 2 authority is fulfilled. This means that the train has completed its authorized route and has reached the end of its designated authority on Line 2. The train has followed all the necessary protocols and has successfully fulfilled its assigned authority on Line 2.

    Rate this question:

  • 8. 

    What does a train authorized by Form D Line 2 to operate in both directions have?

    • A.

      The track to himself

    • B.

      Absolute Block

    • C.

      Exclusive Occupancy 

    • D.

      None of the above

    Correct Answer
    C. Exclusive Occupancy 
    Explanation
    A train authorized by Form D Line 2 to operate in both directions has exclusive occupancy. This means that the train has exclusive rights to use the track and no other trains are allowed on the track while the authorized train is operating. This ensures the safety and efficiency of train operations by preventing any conflicts or collisions with other trains.

    Rate this question:

  • 9. 

    One way another train can be reported clear of DCS territory is by observing the rear markers and engine number, what is the other way?

    • A.

      Observing the schedule number

    • B.

      Observing the train model

    • C.

      Observing the last whole mile post that train passed

    • D.

      Observing the last car number

    Correct Answer
    D. Observing the last car number
    Explanation
    Another way to report a train clear of DCS territory is by observing the last car number. This can be done by visually inspecting the train as it passes or by checking the information provided by the train operator or dispatcher. By noting the last car number, it can be confirmed that the entire train has passed through the designated territory and is clear to proceed.

    Rate this question:

  • 10. 

    A crew being relieved may leave hand-operated switches in either position, as long as the Dispatcher was notified of the switches position.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    When a crew is being relieved, they may leave hand-operated switches in either position, as long as they inform the Dispatcher about the switches' position. This means that the crew is not required to return the switches to a specific position before leaving, as long as they communicate this information to the Dispatcher. This allows for flexibility in the switching operations and ensures that the Dispatcher is aware of the switches' status. Therefore, the statement is true.

    Rate this question:

  • 11. 

    Physical Characteristic locations can be used as a location where DCS territory begins or ends.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Physical characteristic locations cannot be used as a location where DCS territory begins or ends. DCS (Digital Control System) territory refers to a specific area or region that is controlled and monitored by a digital control system. Physical characteristic locations, such as geographical features or landmarks, do not have any direct relation to the boundaries or control of DCS territory. The establishment and determination of DCS territory is typically based on technical and administrative factors, rather than physical characteristics. Therefore, the statement is false.

    Rate this question:

  • 12. 

    Reversing in a specified direction in non-signaled DCS territory must be done at ________.

    Correct Answer
    restricted speed
    Explanation
    When operating in non-signaled DCS (Direct Traffic Control System) territory, reversing in a specified direction should be done at restricted speed. Restricted speed is a cautionary speed that allows the train to be able to stop within half the range of vision and be able to take any necessary action to avoid collisions. This is important in non-signaled territories where there are no signals to indicate the presence of other trains or potential hazards. By operating at restricted speed, the train can proceed with caution and ensure the safety of the operation.

    Rate this question:

  • 13. 

    Who must be notified when a train enters DCS territory at an Interlocking?

    • A.

      Dispatcher

    • B.

      Operator

    • C.

      Conductor

    • D.

      None of the above

    Correct Answer
    D. None of the above
    Explanation
    When a train enters DCS (Distributed Control System) territory at an interlocking, there is no specific requirement to notify the dispatcher, operator, or conductor. DCS is an automated system that allows for remote control and monitoring of train movements, track switches, and signals. The system itself is designed to ensure the safe and efficient operation of trains within the interlocking area. Therefore, there is no need for additional notification to the mentioned personnel.

    • A.

      501

    • B.

      504

    • C.

      562

    • D.

      505

    • E.

      None of the above

    Correct Answer
    A. 501
    Explanation
    ABS Rule 501 governs if a reverse move within the same block is to be made in signaled DCS territory.

    Rate this question:

  • 15. 

    Overlapping Form D authorities for opposing movements may be issued so long that safe train handling procedures are followed.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is false. Overlapping Form D authorities for opposing movements should not be issued, even if safe train handling procedures are followed. This is because overlapping authorities can lead to confusion and increase the risk of accidents. It is important to ensure that there is clear communication and coordination between train movements to maintain safety on the tracks.

    Rate this question:

  • 16. 

    Where would Line 2 authority end if a hand-operated switch is used as the location?

    • A.

      Hand-operated switches cannot be used as a location

    • B.

      1 train length prior to the switch

    • C.

      Fouling point of the switch

    • D.

      At he last mile post prior to the switch

    Correct Answer
    C. Fouling point of the switch
    Explanation
    In railway terminology, the "fouling point" refers to the point on a track where the distance between the switch and the nearest track obstruction is minimized, allowing for safe passage of trains. Therefore, if a hand-operated switch is used as the location, the authority of Line 2 would end at the fouling point of the switch, ensuring that there is enough clearance for trains to pass safely.

    Rate this question:

  • 17. 

    A flagger is required when entering DCS territory at a hand-operated switch.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    When entering DCS (Dispatch Control System) territory at a hand-operated switch, a flagger is required. This means that someone needs to be present to manually operate the switch and ensure the safe movement of trains. The flagger's role is crucial in coordinating with the DCS and communicating any necessary information or instructions. Therefore, the statement "True" is the correct answer.

    Rate this question:

  • 18. 

    How must a train operate when approaching a facing point switch in DCS territory?

    • A.

      Medium speed

    • B.

      Slow speed

    • C.

      Limited speed

    • D.

      Prepared to stop

    Correct Answer
    D. Prepared to stop
    Explanation
    When a train is approaching a facing point switch in DCS territory, it must operate in a manner where it is prepared to stop. This means that the train should be ready to come to a complete halt if necessary, as it approaches the switch. This precaution is taken to ensure the safety of the train and prevent any potential accidents or mishaps that could occur at the switch. By being prepared to stop, the train can effectively navigate the switch and respond to any unexpected situations that may arise.
