How long should one wait after stopping before placing the auto brake valve handle in the release position?

The correct response indicates that one should wait 60 seconds after stopping before moving the auto brake valve handle to the release position. This waiting period is an important safety measure in rail operations.

During this time, it allows for the stabilization of the train's air brake system. When a train comes to a stop, the air pressure within the brake system can fluctuate, and waiting a full minute ensures that all components are settled and that the brakes are fully applied before attempting to release them. Prematurely moving the valve could compromise braking effectiveness and potentially lead to safety hazards.

The time frame of 60 seconds is specifically set based on operational standards, balancing safety concerns and operational efficiency.
