What should a train operator do when facing a stop signal?

When a train operator encounters a stop signal, the appropriate action is to stop the train and remain in that position until a less restrictive aspect, such as a proceed signal, is displayed. This is crucial for maintaining safety on the railway. The stop signal indicates that there is a potential hazard ahead, such as another train occupying the track or an operational issue that needs to be addressed.

By stopping the train, the operator allows for a thorough assessment of the situation by signaling to control centers and ensuring that no further movement occurs until it is safe to do so. This protocol helps prevent accidents and collisions, ensuring the safety of both the train crew and passengers, as well as the integrity of the railway infrastructure. When the signal eventually changes to indicate a more permissive aspect, the train operator can then safely resume travels knowing it is clear to proceed.
