Is it necessary to apply hand brakes during an initial terminal walking brake test?

Applying hand brakes during an initial terminal walking brake test is essential to ensure that the train does not inadvertently move while personnel are conducting the test. This safety measure is crucial, as it helps to maintain control over the train and allows the crew to focus on inspecting the brake systems without the risk of movement.

When performing the walking brake test, the crew checks the functionality of the braking system by walking alongside the train and examining each brake. If the hand brakes are not applied, there is a possibility that the train could roll, especially if there are any slight inclines or if the brakes are not fully reliable.

Maintaining safety during such tests is critical, and the application of hand brakes serves as a precautionary measure, ensuring that the process is conducted without risk. Therefore, their use is deemed necessary for the protection of staff and the integrity of the testing procedure.
