What might be the consequence of a failure to operate the brake properly?

A failure to operate the brake properly can lead to the potential rolling of cars, which is a critical safety concern in train operations. If brakes are not engaged or malfunction, gravity can cause the train or rail cars to move unintentionally, particularly on inclines or when parked on a slope. This situation poses a serious risk not only to the train crew but also to passengers, surrounding infrastructure, and nearby communities.

In the context of train operations, proper brake management is essential for ensuring that the train remains stationary when required and can safely stop during operations. The consequences of improperly managed brakes extend to derailment risks or collisions if the train begins to move without appropriate control, emphasizing the importance of understanding and executing brake operations diligently.
