What must employees ensure when handling switches and derails?

When handling switches and derails, it is crucial that employees ensure switches are properly lined for the intended route. This is important because incorrectly lined switches can lead to derailments or accidents, endangering both personnel and equipment.

Properly lining a switch means that the switch is positioned in a way that directs trains onto the correct track. Employees must check that the switch points are aligned with the track they wish to switch to before a train approaches. This ensures that trains operate safely and as intended, which is vital for maintaining efficient and safe rail operations.

The focus on lining the switch correctly is foundational to safe switching practices, making it the priority in this scenario. Proper alignment safeguards against potential safety hazards, ensuring that all operations on the tracks proceed smoothly.
