    Rate this question:

  • 2. 

    Track cars must approach highway crossings _______________.

    • A.

      At Restricted Speed

    • B.

      Prepared to stop

    • C.

      At Medium Speed

    • D.

      At Slow Speed

    Correct Answer
    B. 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.

  • 3. 

    What rules DO NOT apply to Track Cars?

    • A.

      DCS and CSS

    • B.

      INT and CP

    • C.

      ABS and DCS

    • D.

      ABS and CSS

    Correct Answer
    C. ABS and DCS
    Explanation
    Track cars are high-performance vehicles designed for racing on a racetrack. They prioritize speed, agility, and handling over comfort and convenience. ABS (Anti-lock Braking System) and DCS (Dynamic Stability Control) are safety features commonly found in regular road cars, but they are not typically used in track cars. This is because track cars require more precise control and maneuverability, and these systems can interfere with the driver's ability to fully exploit the car's performance potential. Therefore, ABS and DCS do not apply to track cars.

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

    • A.

      CSS and Int

    • B.

      DCS and ABS

    • C.

      CSS and DCS

    • D.

      ABS and CSS

    Correct Answer
    D. 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:

  • 23. 

    One of the two ways a train may foul or enter ABS territory is verbal permission from the Dispatcher, what is the second way?

    • A.

      A proceed indication on a controlled signal
