    If the Cab Signal changes between fixed signals the Cab Signal will govern subject to the following restrictions. (select all that apply)

    • When the Cab Signal aspect changes to Restricting between Fixed Signals, the Engineer must immediately reduce to Restricted Speed.

    • If an Interlocking Signal requires Medium Speed and the Cab Signal is more favorable, the train must run its length or 500 feet.

    • If the Signal changes from Restricting to more favorable the speed must not be increased until the train has run its length or 500 feet.

    • If the Cab Signal changes from Clear to Approach between fixed signals, trains must immediately begin reduction to limited speed and must approach the next fixed signal at medium speed, unless that signal has a more favorable aspect.

    Correct Answer(s)
    A. When the Cab Signal aspect changes to Restricting between Fixed Signals, the Engineer must immediately reduce to Restricted Speed.
    A. If an Interlocking Signal requires Medium Speed and the Cab Signal is more favorable, the train must run its length or 500 feet.
    A. If the Cab Signal changes from Clear to Approach between fixed signals, trains must immediately begin reduction to limited speed and must approach the next fixed signal at medium speed, unless that signal has a more favorable aspect.
    Explanation
    When the Cab Signal changes between fixed signals, several restrictions come into play to ensure the safe operation of trains. Firstly, if the Cab Signal shifts to a more restrictive "Restricting" aspect, the train's engineer must promptly reduce the speed to a cautious "Restricted Speed." Secondly, when an Interlocking Signal requires "Medium Speed" but the Cab Signal shows a more favorable aspect, the train can proceed but must maintain that speed for its length or 500 feet. Thirdly, if the Cab Signal changes from "Restricting" to a more favorable aspect, the train's speed cannot be increased immediately; instead, it must maintain the current speed for a specified distance. Finally, if the Cab Signal changes from "Clear" to "Approach" between fixed signals, the train must reduce speed immediately and approach the next fixed signal at medium speed, unless that signal displays a more favorable aspect. These restrictions prioritize safety and adherence to signal indications during rail travel.

    • The fixed signal being approached is imperfectly displayed.

    • Damage or fault occurs to any part of the Cab Signal Apparatus

    • When approaching a fixed signal displaying Approach or more favorable aspect in CSS territory without fixed automatic block signals, the can signal displays an aspect more favorable than approach.

    • When approaching a fixed signal displaying Slow Clear, Slow Approach Stop and Proceed or restricting, the Cab Signal displays restricting and fails to conform after passing the fixed signal.

    Correct Answer(s)
    A. The audible indicator fails to sound
    A. The Audible indicator continues to sound even though it was acknowledged
    A. The cab signal failed to 2 fixed signal locations in succession
    A. The fixed signal being approached is imperfectly displayed.
    A. Damage or fault occurs to any part of the Cab Signal Apparatus
    Explanation
    In the context of the NORAC CAB SIGNAL SYSTEM, the Cab Signals are considered to have failed if several specific conditions occur. These conditions include the audible indicator failing to sound, which is a crucial warning signal for train operators. Additionally, if the audible indicator continues to sound even after it has been acknowledged, it indicates a malfunction. The system also flags a failure if the cab signal fails at two fixed signal locations in succession or if the fixed signal being approached is not displayed correctly. Furthermore, any damage or fault occurring in any part of the Cab Signal Apparatus is deemed a failure. These criteria are put in place to ensure the safety and reliability of the signaling system during train operations.
