Under restricted speed, after the movement clears turnouts, crossovers, and power-operated switches, the speed must not exceed:

• A. 15 MPH.
• B. 20 MPH.
• C. 25 MPH.
• D. 30 MPH.

Answer: (B)

Restricted speed means you must be able to stop within the distance you can see and be prepared to slow for any obstruction or signal. Once the movement has cleared turnouts, crossovers, and power-operated switches, the risk from those devices drops, so you can resume a safe, controlled pace on the main track. Twenty miles per hour is the standard limit in this context, giving you enough momentum to observe signals and react to any unexpected conditions without sacrificing safety. Slower speeds would unnecessarily slow movement, while faster speeds could compromise reaction time near track devices and signals.
