Flagman (rail)

A flagman is also assigned to protect a train that has stopped on a section of track.

Before the advent of automated level crossing gates, and still where automatic gates are not installed, flagmen were also assigned to protect the crossings.

For instance on CSX Transportation a train approaching the work area is to call the flagman for permission through the work area.

If workers are in the clear the flagman will advise crew to proceed and advise the crew that workers are not fouling the track.

If a flagman fails to answer, the train crew is required by rule to stop short of milepost location and proceed at restricted speed.
