All movements made on non-controlled track must be made using what speed?

The correct choice is restricted speed, which is essential for ensuring the safety of roadway workers and trains on non-controlled tracks. Restricted speed is defined as a speed that allows a train to stop within half the range of vision of the engineer, taking into account potential hazards that may exist. This governs the operation of trains on tracks where full control measures are not in place, ensuring that any unexpected conditions, such as workers in the area or obstructions, can be detected and addressed promptly.

Operating at restricted speed allows for better reaction times, significantly reducing the risk of accidents or injuries. In contrast, normal operating speed or maximum allowable speed may not account for the presence of workers or unexpected conditions on the tracks, posing a greater risk to safety. While slow and cautious speed may seem safe, it is not a defined term within the RWP guidelines, making restricted speed the appropriate and standardized choice for these situations.
