Signalling Developments

Signalling Developments.

The signalling department forms one of the most important of railway activities, and in recent years many notable improvements have been introduced in train signalling the world over. Of modern devices employed in the signalling field probably the most interesting are the utilisation of day colour light signals, and the development of route signalling.

By the Southern Railway of England there has just been put in hand what promises to become the world's biggest installation of multiple aspect colour light signalling. Already the Southern lines between Holborn Viaduct and Elephant and Castle, and the Charing Cross, Cannon Street and Borough Market junction sections, have been equipped with day colour light signalling, and now the installation is being extended to cover the remaining sections of the London suburban zone. Route signalling finds its pioneer at Home in the Great Western Railway, while across the Channel the Northern Railway of France has made extensive use of this convenient arrangement. Route signalling does away with the operation of points from individual levers, and concentrates all the functions necessary to set up a route and bring the signal to “clear” in the operation of one lever. It also gives great possibilities for the speeding up of movements in large stations and busy traffic centres.
