What is the role of flagman when working limits are established?

In the context of establishing working limits, the role of a flagman is crucial for maintaining safety on the railway. Specifically, the flagman is responsible for ensuring that all train movements are held clear of the working limits. This is important to protect workers who may be engaged in maintenance or construction activities on or near the tracks. By keeping trains at a safe distance, the flagman helps to prevent accidents and ensures that the work can be carried out without the risk of interference from passing trains.

This function is crucial for the overall safety protocols in railroad operations, as establishing clear working limits and enforcing them through the flagman’s vigilance is a fundamental practice in ensuring the well-being of personnel conducting essential maintenance work. The flagman serves as an active barrier against potential hazards, thereby playing a vital role in the system's safety framework.
