What is the requirement for a flagman after stopping a train?

In the context of the Maintenance of Way Operating Rules, the requirement for a flagman after stopping a train is that they must explain to the engineer why the train was stopped. This is essential for maintaining clear communication and safety protocols on the railway. When a train is stopped, it is important for the engineer to understand the reasons behind the halt to assess the situation accurately and decide on the next steps.

This explanation also ensures that all personnel involved are on the same page regarding the circumstances of the stoppage, which could include track conditions, signals, or other operational factors. Clear communication is vital in preventing misunderstandings that could lead to accidents or further complications.

Other options might involve actions that are important in different contexts but are not specifically required immediately following a train stop according to the rules. For example, resuming position, notifying a dispatcher, or waiting for instructions may be relevant but are not prioritized in the immediate aftermath of stopping the train. The fundamental goal is to ensure that the engineer is informed about the situation to facilitate any necessary decisions or actions.
