Answer 1

If a train operator sees a white light being waved on the track, it is a signal to stop the train immediately, as signals are crucial for safety and managing train movements.

Step-by-step explanation:

If a train operator notices a white light being waved to and fro on the track ahead of his moving train, he knows it is a signal for him to stop the train immediately. This type of signal is one of the various visual cues used in train operations to communicate important instructions to the train crew for the safe and efficient management of train movements.

Signals are vital in the railroad system as they ensure that trains do not collide, that maintenance crews are protected, and that rail traffic operates smoothly. Not following these signals can lead to severe consequences, including accidents and derailments. Therefore, understanding and adhering to signal instructions is a critical part of a train operator's job.
