The signs are on a girder on the A4076 St Peter's Road bridge. The Check AWS sign tells the train driver to confirm that the train's Automatic Warning System (AWS) is working. AWS is a safeguard against a driver failing to respond to a signal or misreading its aspect. If a driver fails to acknowledge an AWS warning within two seconds, brakes are automatically applied. Because this intervention occurs at the distant signal (the caution or amber aspect), AWS will stop the train before it reaches the stop (red) signal ahead.
