Kidderminster Diesel Depot, also sometimes referred to as the TMD (Traction Maintenance Depot), stands on the space of ground between the Kidderminster Carriage Shed and the Kidderminster Footbridge, and is used to maintain most of the SVR's fleet of Diesel locomotives. Although visible from the footbridge across the station throat, the site is not directly visible to SVR visitors until they have boarded a train and are departing towards Bewdley. The Depot is normally closed to the public, but may be open during special events such as Diesel Galas and the annual Open House Weekend.
Although the names 'Diesel Depot' and 'Traction Maintenance Depot' are synonymous and refer to the entire site, the term 'Diesel Depot' is frequently used to refer specifically to the large workshop building opened in 2016.
In July 2018 the depot was given a TOPS location code - 65942, KI.
Early plans for a Diesel Depot maintenance building involved re-erecting a building from the former Burton-upon-Trent Diesel Depot, originally bought by The Western Locomotive Association, dismantled and stored at Kidderminster. However it transpired that changes to building regulations would have made the cost greater than if new steelwork was used, and the plans were shelved.During the mid-2000s, plans for a purpose built facility were drawn up at the request of the SVR(H) Board. These were approved and detailed design work was under way when the SVR was hit by the 2007 flood damage. After a delay while repairs to the railway were made, a revised plan was prepared in 2009 which reduced the amount of contaminated ground that would need to be removed where the facility would be built. Fund raising at the time included the proceeds of the Autumn 2009 SVRA raffle. Members of Wyre Forest District Council’s planning committee approved an application in March 2013 and 2014 saw the site cleared by the groups who had locomotives and parts stored there, vegetation cleared and the track lifted in preparation. Construction of the new restoration and storage building eventually took place during 2015. Principal contractor was C21 Construction Ltd.
This valuable facility contains three roads, with facilities including a pit and an overhead crane allowing the restoration of these complex but useful locomotives to take place. Previously facilities had been in the open air, with volunteers being exposed to the elements. The new depot provides 1,000 square meters of covered space, two locomotive inspection pits, lifting jacks, and a 10 tonne overhead travelling crane. The first locomotives entered the Diesel Depot on 30 January 2016. On 20 May 2016 the Chairman of Network Rail unveiled a plaque to celebrate the opening of the Diesel Depot.
The Depot is also home to a separate mess room facility for diesel group volunteers, as well as one of the railway's sleeping coaches, which offers overnight accommodation to volunteers.
- Kidderminster TMD appeal November 2016 - In November 2016 the SVR's Diesel Groups and the Severn Valley Railway Charitable Trust Ltd launched a fundraising campaign to improve facilities, ring fenced for diesel projects only. These include a purpose-built workshop for restoring and maintaining component parts, and an amenity block for overnight accommodation, toilet and washing facilities. As of 2020[update] this appeal refers intead to "funding of a raft of new equipment for the Diesel Depot [..] mostly aimed at making the work there safer and more efficient".
- New lifting jacks - In 2017 SVR(H) purchased four new 35t Mechan lifting jacks with a total cost of £122,426, £58,300 of which was funded by the Diesel Groups, a shareholder and other donations. These jacks can lift all diesels currently based on the Railway and offer the opportunity for further contract work.
- In September 2017 trackwork remodelling allowed access and stabling outside all shed roads in the South yard.
- AWS ramps - In April 2018 the railway obtained from Network Rail and Siemens two AWS ramps recovered from Birmingham New Street Resignalling (Phase 4/5), which were installed in Kidderminster Yard to test home fleet and visiting locomotive AWS systems before they leave for the main line.
