AHB (Automatic Half-Barrier) Level Crossing

AHB (Automatic Half-Barrier) Level Crossing

A level crossing with lights and barriers to control road traffic. The barriers at this type of crossing only extend across half of the road, leaving a space for traffic to exit the crossing at all times.

The barriers lower automatically on the approach of a train without intervention by the signaller.

A typical AHB crossing is illustrated here:

See Level Crossings for other types.
