What does 'clearance' mean in the context of railway safety?

In the context of railway safety, 'clearance' refers to the distance workers must maintain from the center of a track. This concept is essential for ensuring the safety of personnel in proximity to train movements. Maintaining proper clearance minimizes the risk of accidents and injuries, as it helps to ensure that workers are at a safe distance from potentially moving trains and other rail operations.

This safety distance is determined based on operational guidelines, and it often takes into account factors such as the speed of passing trains and the physical dimensions of the rail equipment. Compliance with clearance distances is crucial for the protection of workers and for the smooth operation of train services.
