What is the role of a train conductor?

The role of a train conductor primarily involves supervising the crew and managing train operations. This includes ensuring that all aspects of the train's operation run smoothly and efficiently. Conductors are responsible for coordinating the activities of the train crew, communicating with both the train engineers and dispatchers, and making critical decisions that affect the safety and timetable of the train.

Additionally, conductors manage passenger services, ensuring safety and compliance with regulations during transit. They play a crucial role in enforcing safety protocols onboard and may be involved in checking tickets or providing assistance to passengers. Their authority extends to making operational decisions, such as when to stop for emergencies or delays.

This understanding highlights the critical function of conductors in the overall system of train operations, while the other roles mentioned in the choices pertain to specialized tasks performed by different members of the train crew.
