Warning lights and alarms

Illuminated white or orange warning lights are provided at locations where workers on track have a restricted view of approaching rail traffic. If rail traffic approaches, the lights go out.

FIGURE 11: Examples of warning lights.

Illuminated white crossing lights, sometimes combined with audible warning devices as additional alarms, are provided at pedestrian crossings restricted to use by rail workers.

If rail traffic approaches, the lights go out and alarms are activated in time for workers to go to, or remain in, a safe place.
