Changes

Construction of the two signal boxes at Bewdley was authorised by the GWR Board in October 1877 as part of the opening of the Kidderminster Loop line. They were the first 'proper' signal boxes on the Severn Valley Railway, all other boxes dating from after 1880<ref>[[Bibliography | Marshall (1989), p128]]</ref>. There is uncertainty as to whether the current Bewdley North and Bewdley South are these original 1877/78 built boxes, or marginally later replacements. Bewdley North has a 37 lever GWR 3-bar horizontal tappet frame with 5" centres between the levers, meaning the frame is noticeably longer than that at Bewdley South despite having only three more levers. With the exception of the distant levers, which are painted yellow in accordance with practice since the late 1920s, the levers are painted in line with GWR instructions from the Edwardian period, with goods line signals having a central black stripe on otherwise red levers, and the Back Road signal levers being painted to indicate relief lines, with half black/half red levers. The signal box is the only place in the world still utilising 'pegging' (i.e. capable of giving a line clear to the box in rear) GWR Spagnoletti block instruments on the standard gauge. The Back Road instrument is a non-pegger over pegger double deck instrument, whilst the Up and Down Main instruments are single deck separate pegger and non-peggers, originating from Marshbrook Signal Box on the Shrewsbury - Hereford line.
