The automatic warning system (aws) it is a device that triggers the automatic application of brakes if the signal is indicating danger and the driver has not taken any action. The system consists of a track device located at a desirable braking distance at the rear end of the first stop signal. The track device is activated when the signal indicates danger and is ineffective when the signal is ‘clear’. Alarm will sound if driver don’t take action during a stop signal.

The signals must be at least the stopping distance of a train apart. At the ends of the sidings are the signals termed headblock signals. These signals indicate whether it is safe to proceed to the next siding.

Manual block signal indications were simple: stop, the block is occupied; proceed, the block is clear; and proceed at restricted speed prepared to stop short of a preceding train. Because trains had to approach each station prepared to stop, the “distant” signal was developed to give an advance indication of whether a stop was required at the “home” signal.
