    If a train encounters an ABS failure and DCS rules now govern movement, what rules no longer apply to the movement of that train?

    • CSS and Int

    • DCS and ABS

    • CSS and DCS

    • ABS and CSS

    Correct Answer
    A. ABS and CSS
    Explanation
    When a train encounters an ABS failure and DCS rules now govern movement, the rules that no longer apply to the movement of that train are ABS and CSS. ABS (Automatic Block Signaling) is a system that uses track circuits to detect the presence of trains and control their movement, while CSS (Centralized Traffic Control System) is a method of controlling train movements through a centralized control center. In this scenario, with ABS failure, DCS (Distributed Control System) takes over, which is a different method of controlling train movements. Therefore, ABS and CSS rules become irrelevant.

    Rate this question:

  • 11. 

    Track cars must approach highway crossings _______________.

    • At Restricted Speed

    • Prepared to stop

    • At Medium Speed

    • At Slow Speed

    Correct Answer
    A. Prepared to stop
    Explanation
    Track cars must approach highway crossings prepared to stop because these crossings are potentially dangerous intersections where trains and vehicles can collide. By being prepared to stop, track cars can ensure the safety of both themselves and other vehicles on the highway. This allows them to assess the situation, check for any oncoming trains, and take necessary precautions to avoid any accidents or collisions. Approaching at a slower speed and being prepared to stop gives track cars the ability to react quickly and prevent any potential accidents.

    • Approach

    Correct Answer
    A. Advance Approach
    Explanation
    When a train exceeds Limited Speed, it must begin reducing its speed to Limited Speed as soon as the engine passes the Advance Approach signal. The Advance Approach signal indicates that the next signal is displaying a more restrictive aspect, so the train needs to prepare to stop at the second signal ahead. This signal serves as a warning to the train crew to start slowing down and be prepared to stop if necessary.

    Rate this question:

  • 13. 

    Within how many seconds must a cab signal conform to a fixed signal?

    • 6 seconds

    • 10 seconds

    • 5 seconds

    • 4 seconds

    Correct Answer
    A. 6 seconds
    Explanation
    A cab signal must conform to a fixed signal within 6 seconds. This means that when a fixed signal is displayed, the cab signal in a cab or train must match that fixed signal within 6 seconds. This ensures that the cab or train is following the correct signal indications and helps maintain safety and coordination with other trains on the track.

    Rate this question:
