Flagman (rail)

A Flagman (rail) is a railway worker whose primary duty is to provide protection for train movements or maintenance activities on or near a railway track. The role involves using flags, lights, or other signaling devices to warn oncoming trains of potential hazards, obstructions, or ongoing work.

Specifically, a flagman may be stationed to:

• Protect workers performing maintenance or repairs on the track, bridges, or other railway infrastructure.
• Warn of obstructions on the track, such as fallen trees or debris.
• Protect trains during emergencies, such as derailments or accidents.
• Direct train traffic during temporary track outages or diversions.
• Provide warning at grade crossings where automatic warning systems are not functioning correctly.

The flagman's signals are essential for preventing collisions and ensuring the safety of both railway workers and the public. Their duties often require them to be vigilant and communicate effectively with train crews and other railway personnel. The specific procedures and signals used by flagmen are typically governed by railway operating rules and regulations which vary by country and railway company. The use of a flagman can be mandated by regulations or standard operating procedures, and their presence provides a critical layer of safety in potentially hazardous railway environments. Modern railway systems are increasingly employing automated signaling and train control systems, which may reduce the need for flagmen in some situations, but the role remains important, especially during maintenance and emergency operations.
