What is required when a train sees a Terminal Restricting signal?

When a train sees a Terminal Restricting signal, it indicates a need to proceed at Restricted Speed. This is critical for ensuring safety as it allows the train crew to manage the train's movement under uncertain or potentially hazardous conditions, such as entering a terminal or yard area where the environment may change rapidly.

Restricted Speed means that the train must operate at a speed that allows the engineer to stop within half the distance of vision ahead, which is particularly important in areas where track conditions, the presence of work crews, or other trains may pose a risk. Therefore, complying with this requirement helps prevent accidents and ensures the safe operation of trains within terminal areas.

Proceeding at full speed or maximum authorized speed would be inappropriate as those speeds do not provide the necessary reaction time required to respond to unexpected circumstances. Stopping until further notice would also not align with the operational protocols for this type of signal, as it would unnecessarily delay train movements unless specific instructions dictate that a stop is needed.
