A signal box at [[Bridgnorth]] that works to [[Hampton Loade signal box|Hampton Loade]] (short section) or [[Highley signal box|Highley]] (long section) using [[Single line working using tokens|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 Down side, where the two lines converged into the single line. The foundations can still be made out on the embankment side. Bridgnorth South Signal Box was at the south end of the station on the Up side, opposite [[Bridgnorth#Pan Pudding Hill | Pan Pudding Hill]] where it could control access to the goods yard<ref>[[Bibliography#Books Marshall (1989), p131]]</ref>. A photo of the latter box circa 1900 appears in SVR news edition 44. In 1923 both boxes were replaced by a large single central signal box with 54 levers, and a track circuit was installed to lock the Up starting signal.<ref>Great Western Railway Magazine, March 1923</ref><ref>[[Bibliography#Books Marshall (1989), p134]]</ref>. It was far larger than Bridgnorth Station layout really required with many spaces in the lever frame. This was future-proofing for alterations required for the [[Unsuccessful proposals for railways in the Severn Valley#Proposals for railways connecting Wolverhampton and Bridgnorth|planned line to from Wolverhampton that ]] which reached Kingswinford in 1925 but was never constructedcompleted. This The box was closed by BR on 2 December 1963, and the upper structure was demolished in 1965 just before the arrival of the SVR Society<ref>[[Bibliography#Books Marshall (1989), p166]]</ref>.
The masonry 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<ref name="SRSSignalBoxRegister_Update9">Signal Box Register, Volume 1: Great Western, revised 2011 edition, Signalling Record Society (plus correction sheet #9 )</ref>, 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 SVR extended southwards<ref>[[Bibliography#Books Marshall (1989), p200]]</ref>.
