A train entering a block between signals must proceed at ______________________ until the ___________________ has entered the block and the entire train has passed the next block signal.

A train entering a block between signals must proceed at ______________________ until the ___________________ has entered the block and the entire train has passed the next block signal.

• A. Restricted Speed / entire train
• B. Normal Speed / leading end
• C. Maximum Speed / caboose
• D. Cautious speed / front portion

Answer: (A)

Entering a block between signals requires moving under restricted speed. This speed level keeps the train able to stop within the distance you can see ahead and to react to signals or obstructions, since you don’t yet have the full protection of the next signal. The rule specifically uses restricted speed until the entire train has entered the block and has passed the next block signal, after which normal operations can resume. Restricted speed is the safety margin that ensures you can stop in time if the signal ahead changes or if there’s an unexpected obstruction. The other speeds don’t provide that safety margin or are not defined for this scenario under NORAC rules.
