Signalling Control - Present Day

Present Day

While rare, some traditional signal boxes can still be found. Some still control mechanical points and signals, although in many cases, the lever frame has been removed or is out of use, and a control panel or VDU has been installed. Most modern countries have little, if any, mechanical signalling remaining on the rail system. Both in the UK and Ireland, however, mechanical signalling is still relatively common away from the busiest lines; there is also a considerable amount in the former East Germany. Traditional signal boxes can be found on many heritage railways.

The modern control centre has largely replaced widespread signal cabins. These centres, usually located near main railway stations, control the track network using electrical or electronic systems. One such system is CTC, Centralised Traffic Control.
