How often should locomotive engineers perform safety checks?

Locomotive engineers should perform safety checks before every shift or ride to ensure the safe operation of the train. This practice is crucial because it allows engineers to identify any potential mechanical issues, safety hazards, or required maintenance tasks before they take the train out on the tracks. Conducting thorough inspections each time the engineer is set to operate a train minimizes the risk of accidents and enhances overall safety for both the crew and passengers. Regular safety checks are part of a preventive approach to maintenance, anticipating problems before they occur rather than reacting to them after the fact.
