What does the term 'working limits' refer to?

The term 'working limits' refers to a defined area on the track where authorized train operations are regulated to ensure safety, particularly when maintenance work or other potentially hazardous activities are happening. In this context, working limits establish parameters within which train movements can be safely coordinated and managed, minimizing the risk of collisions with maintenance personnel or equipment present on the track.

This concept is essential for maintaining both the safety of workers performing necessary maintenance tasks and the safe passage of trains. It helps communicate to train operators the areas where they may encounter work activities and the regulations that apply to train operations within those boundaries. Thus, working limits serve as a critical safety measure within the broader operational framework of rail transport.
