When a train or engine is on a siding, how close can the employee attending the switch be?

The correct answer indicates that an employee attending a switch while a train or engine is on a siding must maintain a distance of no nearer than 150 feet. This distance is crucial for maintaining safety in rail operations. It allows sufficient space for the employee to react to potential hazards, such as the train moving unexpectedly or in the event of an emergency.

This practice is grounded in standard safety protocols that prioritize the protection of personnel working around moving equipment. Such protocols help prevent accidents and ensure that employees can perform their duties without unnecessary risk. Understanding and adhering to these distance guidelines is essential for maintaining a safe working environment within the rail industry.
