The Ericsson Group have designed, manufactured and marketed railway signalling equipment since 1915. The product range has included such systems as signalling equipment for the track, safety systems for the train routing, remote control systems and systems for supervising the speed. The product range has successively been renewed in step with the technical development. The development in the fields of electronics and computers has contributed greatly to this renewal. This article deals with the background and the present scope of this work. Some of the recently developed systems will be described in greater detail in subsequent issues of the magazine.
