What is a critical aspect to check after the brakes are released and before the train departs?

It is essential to inspect each brake to ensure they have released after the brakes are applied and just before the train departs. This check is critical because if any brakes remain applied, it can lead to serious safety hazards such as excessive wear on the braking system, increased stopping distances, or even train derailment. A thorough inspection helps ensure that the train operates as intended and that all components are functioning correctly, contributing to the overall safety and efficiency of the journey. Maintaining the integrity of the braking system is paramount for safe train handling and operation, making this inspection a key aspect of pre-departure checks.
