How do conductors contribute to passenger safety during normal operations?

Conductors play a vital role in ensuring passenger safety during normal operations by rigorously adhering to and enforcing all safety protocols and regulations. This includes conducting safety briefings, checking that safety equipment is operational, ensuring that passengers board and disembark safely, and monitoring compliance with rules that govern train operations. Their knowledge of emergency procedures and ability to respond quickly and effectively to any incidents further enhance the safety of passengers, ensuring a secure travel experience.

The other options involve important aspects of the service provided on the train but do not directly address the core responsibility of maintaining passenger safety. While providing entertainment and refreshments, maintaining cleanliness, and managing sales might enhance the overall travel experience, they do not encompass the fundamental safety obligations that conductors must prioritize during operations.
