What must be checked to ensure proper application of the brakes before moving a train?

Before moving a train, it is essential to ensure that all air and hand brakes are released. This is critical because if any brakes are left engaged, it could result in an inability to move the train or could cause damage to the braking system and other train components.

The air brakes are a primary system used for stopping and controlling the movement of the train. If the air brakes are not fully released, they will create resistance, leading to increased wear and potential malfunction. Hand brakes, which are used as a supplementary measure, must also be fully released; otherwise, they could impede train movement and create safety hazards.

Ensuring that both the air and hand brakes are released is a fundamental step in maintaining operational safety and efficiency in train operations. This procedure is standard protocol and critical for preventing accidents during the train's departure as well as ensuring that it can move freely without unintended hindrances.
