A signal box at Bridgnorth that works to Hampton Loade (short section) or Highley (long section) using ETT regulations.

Bridgnorth has had a number of signal boxes during its existence. Initially construction of two boxes was authorised in 1891 and these were brought into use in October 1892. Bridgnorth North signal box was situated north of the station on the DownIn reference to the direction of travel means away from the major terminus (i.e. towards Bridgnorth on the present day SVR) side, where the two lines converged into the single line. Bridgnorth South Signal Box was at the south end of the station on the UpIn reference to the direction of travel means towards the major terminus (i.e. towards Kidderminster on the present day SVR) side, opposite Pan Pudding Hill where it could control access to the goods yard[1]. A photo of the latter box circa 1900 appears in SVRSevern Valley Railway news edition 44. In 1923 both boxes were replaced by a single central signal box[2]. This was closed by BRBritish Rail or British Railways on 2 December 1963, and the upper structure was demolished in 1965 just before the arrival of the SVRSevern Valley Railway Society[3].

The masonary base of the former central signal box was originally slightly longer than it is today. Evidence of this truncation may be found by inspection of the brickwork towards the northern end on the front wall. The upper timber section was replaced by an ill-fitting box originally built in 1925 which was relocated from Pensnett in December 1968 and erected during the following year. The frame originated from Windmill End Junction signal box[4], with parts of the interlocking and signalling instruments taken from Arley signal box, which would later require that box in turn to be re-equipped when the SVRSevern Valley Railway extended southwards[5].

The signal box suffered a fire on the night of 1 January 1977. This initially started in the mains electricity switch-gear under the staircase; the staircase and surrounding floorboards were well alight before the fire brigade arrived. Structural damage was mainly confined to the south end of the box, but smoke and water damage was caused to much of the equipment. The burnt woodwork had been replaced by mid-February, and the burnt wiring replaced on a "make do and mend" basis in time for the 1977 running season[6]. Further work was done to the box as part of a major re-laying of track at Bridgnorth which began at the end of 1977[7] and was completed in autumn 1978[8].
