After lining the switch for a train to enter or leave the main track, where must the employee attending the switch be positioned?

The correct position for the employee attending the switch after lining it for a train to enter or leave the main track is on the opposite side of the main track. This positioning is crucial for maintaining safety and providing the employee with a clear line of sight. Being on the opposite side allows the employee to observe the train as it approaches, ensuring that they can monitor its speed and any necessary signals.

This vantage point also helps minimize the risk of injury, as standing on the side of the main track keeps the employee safely away from the train's path. It is essential to have an unobstructed view and adequate reaction time should circumstances change, such as the train stopping unexpectedly or signaling for another action. Proper positioning reduces hazards and helps ensure a smooth transition for the train onto the main track.
