If a train stops after passing a block signal for reasons other than a passenger stop, how must it proceed?

When a train stops after passing a block signal for reasons other than a passenger stop, it must proceed at Restricted Speed until the next signal is seen. This is important because taking such precautionary measures ensures the safety of both the train and any other trains that may be on the same track.

Restricted Speed allows the train to travel at a speed where it can stop short of any obstruction, allowing the crew to react appropriately to signals or conditions ahead. This is especially crucial in situations where visibility may be limited or where other potential hazards could exist.

If the train were to proceed at normal or high speed, it could lead to dangerous situations if there were unforeseen problems on the track. Therefore, maintaining Restricted Speed helps to reinforce safety protocols in the event a train must stop unexpectedly after a block signal.
