When encountering a Terminal Restricting signal, what speed should the train proceed at?

When encountering a Terminal Restricting signal, the train should proceed at Restricted Speed to ensure safety and compliance with operational protocols. Restricted Speed typically means proceeding at a speed that allows the train to stop within half the distance of the sighting distance and is usually at a slow pace that ensures the train can react promptly to any obstacles or signals ahead.

This is particularly important in terminal areas where the environment can be congested or where there may be workers present on or near the tracks, reducing the chances of accidents caused by unexpected stops or movements. By adhering to Restricted Speed, conductors can maintain control of the train and ensure safe operation through potentially hazardous areas.

The other options would not be appropriate in this scenario as they do not prioritize safety in terms of operational procedures, especially in areas where caution is paramount.
