Automatic Block Signalling
Automatic block signalling (ABS) is a method of railway signalling whereby a railway line is divided into a succession of track sections or blocks. Axle counters are installed at the ends of these sections to enable continuous train detection along the rail line. These axle counters then control the stop signals, governing train entry into an automatic block section.
ABS makes it possible for trains travelling in the same direction to safely follow each other without the risk of rear-end collisions. This makes the use of an ABS system very cost-effective and leads to an increase in capacity.
