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 Down Yard operated as through sidings. Operation to Kidderminster is via Acceptance Lever.
The box passed almost immediately from British Rail's care into the hands of the SVR, and coupled with the only minor alterations the track layout it controls has undergone, it is one of the most 'original' signal boxes in preservation, retaining its 1909 lever frame, pre-preservation block shelf and rear wall furniture, including a token instrument cupboard (one of the originals working either to Stourport, Kidderminster or Bewdley North via the Back Road) and cupboards, phone board and train register desk, complete with curve worn into it by generations of signalmen leaning against it! The box also contains a table, box stool, and short bench which possibly date to pre-preservation days. Two armchairs and a GWR table chair ex-Gloucester S&T offices provided in 1993 complete the furnishings.
The box won a National Railway Heritage Award, the Westinghouse Signaling Award, in 2007. [1]

Diagram
Signalling diagram in Bewdley South. The circles on the diagram are track circuit indicators, which light in the presence of a train (or failure of a track circuit), the pilot light in bottom left being constantly lit to indicate that the power is on.
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 [2].
Labelled diagram of Block Shelf
The lever frame and block shelf at Bewdley South. The descriptions for the labelled items are as follows:
- A: Signal arm repeaters for Lever 0 (Down Distant, top indicator) and Lever 1 (Down Home, bottom indicator)
- B: Signal lamps repeater
- C: Possession key for Bewdley South-Kidderminster section, removed from the instrument to protect the line during engineering work, etc.
- D: Block bell from Kidderminster
- E: Block instrument to Bewdley North for Up and Down main
- F: Block bell to Bewdley North for Up and Down main
- G: Block instrument to Bewdley North for Back Road
- H: Block bell to Bewdley North for Back Road
- I: Track circuit indicator for "Tunnel Track" (extends between the distants at Bewdley South and Kidderminster, either side of Bewdley Tunnel)
- J: Up train accepted (by Kidderminster) indicator
- K: Lever 27 Free/Locked indicator (locks Lever 27 Reversed when Bewdley North clears the Backing Signal on the Down Main)
- L: Signal 30 approach locking Free/Locked indicator
- M: Signal arm repeater for signal 30 (Up Starting)
- N: Signal arm repeater for signal 33 (Up Main Distant)
With the exception of B, the block shelf equipment in Bewdley South is all of BR(W) design, meaning the signalling in the box largely represents a 1950s/60s scene (though quite different to Bewdley South in that period due to post-preservation alterations).

History before preservation
Construction of the first 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[3]. There is uncertainty as to whether Bewdley North and Bewdley South are these original 1877/78 build boxes or later (19th century) replacements.
The lever frame in the Box dates from 1909 and has an early example of standard GWR three-bar vertical tappet interlocking. The interlocking has had minor alterations in preservation to suit preservation needs, but much is as it was prior to 1970.
Bewdley South signal box closed under BR ownership on Saturday 3 January 1970. The Train Register recording the closure is on display in The Engine House at Highley.
Signalling controlled from the Box
Most of the signals at Bewdley South are of late GWR/BR(W) steel tubular post and enamel arm design, however Signals 5, 6, 7, 9, 14 and 20 are mounted on two wooden post bracket signals and are of the earlier GWR 'wasp-tail' design. Many of the signals at Bewdley South are of pre-preservation vintage, because the layout has been so little altered. However, the large bracket outside of the signal box carrying signals 6, 7, 9 and 14 did not carry signal 14 or Bewdley North's Down distant signals pre-preservation, and the opposite bracket carrying signals 5 and 20 did not carry the bracket for signal 20 or a distant either, and it has been shortened somewhat to combat rot discovered in the lower end of the post. The wooden posts on the larger bracket were replaced in 2006.
Signals 0 and 33, the Down and Up Distants respectively, are motor worked. Signal 33 is mounted beneath Bewdley North's Signal 3, and is electrically slotted.
