The office copy of the GWR/BR-era diagram for Bewdley South. The diagram shows alterations to remove the signals and points for the Down Yard. The SVR was given control of the yard before BR ceased running services to Bewdley, and it is thought that the pointwork for the yard was never physically removed. Instead, it is theorised that the removal of these features of the diagram was done to indicate to signalmen that they were not to be used under any circumstances <ref>Severn Valley Signalmen Facebook group</ref>.

Bewdley South signal box
Interior of Bewdley South signal box
Award won by Bewdley South signal box

A signal box at Bewdley, working to Bewdley North and Kidderminster. Bewdley South signal box has interesting arrangements in that it works to Bewdley North by Absolute Block on the main line (platforms 1 & 2), by direction levers under ETT Regulations on the Back Road (platform 3) with the Rock Siding and DownIn reference to the direction of travel means away from the major terminus (i.e. towards Bridgnorth on the present day SVR) Yard operated as through sidings. Operation to Kidderminster is via Acceptance Lever.

The box won a National Railway Heritage Award, the Westinghouse Signaling Award, in 2007.
