Which of the following is NOT a responsibility of a watchman?

A watchman plays a crucial role in ensuring the safety and efficiency of railroad operations. Their primary responsibilities include providing warnings of approaching trains, monitoring track conditions, and communicating any unsafe conditions they observe.

The responsibility of directly operating the train does not fall under the watchman's duties. Operating a train requires specialized training and certification, typically attributed to engineers and conductors who are responsible for the actual movement and control of the train. The watchman's role is to serve as an observer and signaler, ensuring that safety protocols are followed and that those in charge of the train are adequately informed about track conditions and other relevant safety information. Thus, the choice related to directly operating the train is clearly outside the scope of a watchman's responsibilities.
