Hebden Bridge signal box A number of signal boxes in England are on the Statutory List of Buildings of Special Architectural or Historic Interest. Signal boxes house the signalman and equipment that control the railway points and signals. Originally, railway signals were controlled from a hut on a platform at junctions. In the 1850s, a raised building with a glazed upper storey containing ...
The signal box provided a dry, climate-controlled space for the complex interlocking mechanics and also the signalman. The raised design of most signal boxes (which gave rise to the term "tower" in North America) also provided the signalman with a good view of the railway under his control. The first use of a signal box was by the London ...

A particular signal box may control one or more stop signals on each running line. In a traditional mechanically signalled area in the United Kingdom, it is most common for a signal box to have two stop signals governing each line. The first reached by a train is known as the home signal.
A mechanical lever frame inside the signal box at Knockcroghery in Ireland Waterloo station A signalbox, LSWR (Howden, Boys' Book of Locomotives, 1907). Mechanical railway signalling installations rely on lever frames for their operation to interlock the signals, track locks [1] and points to allow the safe operation of trains in the area the signals control.
The signal box was designed and built by the London, Midland and Scottish Railway (LMS) to replace an earlier timber signal box that stood on a gantry. It was opened in January 1940. In the years approaching the Second World War, and in the early years of the war, precautions were taken to protect existing signal boxes from enemy bombing.
From 2005, the technology used in the box was increasingly outdated and spare parts were in short supply. Network Rail began reducing its area of operation as part of its work to digitise signalling on the railway network. [12] The box closed on 24 December 2022, with its functions transferred to Saltley Rail Operating Centre. [13]
