What must be confirmed by crew members before leaving a hand-operated main track switch?

Before departing a hand-operated main track switch, crew members must confirm the position of the switch. This is vital for ensuring that the switch is properly set for the intended route of the train. A misaligned switch could lead to derailments or collisions if the train is directed onto an incorrect track.

Checking the position of the switch is part of the protocol to ensure the safety of the train crew, passengers, and freight while also maintaining the integrity of the overall rail system. Confirming that the switch is in the correct position enables the crew to proceed confidently, knowing they are on a safe path.

In the context of train operations, the focus is always on ensuring the secure and correct alignment of tracks before any movement takes place, making this confirmation not just a routine task but a critical safety procedure.
