When should you release the brakes on a stopped train?

Releasing the brakes on a stopped train should be done only when you are ready to depart. This ensures that safety protocols and operational readiness are observed before movement resumes. It is crucial to maintain a secure and controlled environment while the train is stopped, especially to allow for any necessary inspections, communications, or adjustments that need to be made before departing.

Releasing the brakes prematurely could lead to unintended movements of the train, which may pose risks to personnel or equipment. Furthermore, waiting until you are prepared to move helps maintain better control over the train's operations and minimizes the chance of unplanned stops or accidents.

The other options suggest actions that do not prioritize the safety and readiness necessary for departing a station or stop. For example, stopping the train and immediately releasing the brakes can compromise control, while checking fuel levels is a separate operational concern that should be addressed according to the specific procedures in place. Thus, ensuring that you are ready before releasing the brakes is aligned with best practices for train handling and safety.
