Dutch railway signalling
The current Dutch railway signalling system operated by ProRail has been in effect since 1954 on the Nederlandse Spoorwegen network. As such, it is also referred to as NS'54.
It was designed to be one of the simplest in Europe and is integrated to the ATB, the system of cab signalling widespread on the Dutch network.
Dutch trains normally use the right-hand track and the signals are placed at the right of the track; in sections also equipped to run on the left track, the signals are placed on the left.
