Modern Signalling in Britain
Modern Signalling in Britain.
Resignalling schemes, undertaken in many British passenger termini in recent times, have added vastly to efficiency while making for more economical operation. One of the most interesting re-signalling jobs just completed is the installation of power signalling on a big scale at St. Enoch Station, Glasgow, L.M. and S. Railway. At this terminal there are handled all the “Midland” Anglo-Scottish trains to and from St. Pancras Station, London, as well as a heavy coastal and suburban business. Opened to traffic in 1901, St. Enoch Station has twelve platforms, totalling in length 9,500ft. About 350 trains pass in and out daily, and the station handles more than 6,000,000 passengers annually.
Until recently signalling of the Sykes' electro-mechanical type was employed at this important Scottish terminal. Now, with a view to securing increased efficiency and economy, this arrangement has been replaced by a modern power installation with electrically - operated points and colour light signals, and throughout track-circuiting of running lines. A single cabin has replaced the five cabins formerly necessary for signaling supervision, this cabin having 203 levers electrically interlocked, as compared with the 660 levers and slides in the five signal boxes which have been replaced. Among the many useful features of the new installation may be noted the fitting of ground locks to the point machines, an additional precaution to the usual track locking of point levers; and the furnishing of all main-line signal levers with approach locking.page 20
