Automatic half-barrier level crossings
Automatic Half Barrier
Amber lights and audible warnings followed by flashing red lights warn that a train is approaching and that the barriers are about to come down. You must STOP. The red lights flash all the time the barriers are down, but the audible warning might stop. If another train is approaching, the barriers will stay down; the lights will continue to flash and, if there is an audible warning, the sound will change.
