When is it critical for a train operator to pay close attention to any indicators of hazards?

A train operator must maintain a heightened level of awareness regarding potential hazards throughout the entire course of train operation. This includes not only routine tasks but also unexpected conditions that may arise at any time during the journey. Staying vigilant helps ensure the safety of passengers, crew, and infrastructure by enabling the operator to respond promptly to any indicators of danger, such as obstacles on the tracks, changes in weather conditions, or mechanical issues.

Paying attention solely during maintenance checks, switching tracks, or scheduled inspections does not account for the real-time risks that can emerge during normal operation. Therefore, a comprehensive approach that encompasses all phases of train operation is essential for the overall safety and effectiveness of train operations.
