Railway Signalling

The railway signalling system ensures a quick, efficient and, in particular, safe management of rail transport.

 

 

The railway signalling system ensures a quick, efficient and, in particular, safe management of rail transport. It concerns the technical devices which protect critical points (switch-points and stations, open lines between stations, road-rail level crossings, and other). The system provides a centralised traffic control in large regions, ensuring that rail transport is operated in an optimal manner.  Moreover, routine procedures previously carried out by the railway signalling staff are automated in the signalling system, which significantly reduces potential human error, which typically presents the highest safety risk in rail transport.

In simple terms, railway signalling comprises safety signs and colour light signals along the line connected to the central device through switch-points and other devices along the train route. The signals are used by the traffic management staff to communicate to the train engine driver whether or not the train can continue its journey, and whether the journey needs to be made at reduced speed, subject to the position and geometry of the line, type of route (level or graded), current traffic situation, and other.
