The SVR's DMU is owned and operated by [[The DMU Group (West Midlands) | DMU group]] . The DMU Group operates five cars. These which can be used as separate three 3-car and two 2-car units, but are usually although historically they have regularly been combined to form a five 5-car unit for purposes such as the summer Scenic Cruises. From time to time maintenance requirements may result have also resulted in operation as a four 4-car unitas pictured above.

The first 2 powered driving cars, '''DMBS M51941 51941''' and '''DMCL M52064 52064''' were both withdrawn from BR service in November 1990.<ref name=OurUnits>[https://www.svr-dmu.org.uk/1_3_our-units.html DMU Group 'Our Units']</ref> They were acquired by the embryonic DMU Group and both arrived on the SVR by rail from Doncaster via Tyseley on 30 March 1990, initially on a two -year loan. The Having been re-liveried into original green livery, the 2-car set was formally commissioned on 13 October 1991. After a return trip from Kidderminster to Bridgnorth, the MD of Regional Railways presented the key to officers of the [[The DMU Group (West Midlands)|DMU Group]].<ref>SVR News 102</ref>

It arrived on the SVR on the 7 June 1992 and after being repainted into green livery, it entered service in November of that year to form a 3-car unit. <ref name=OurUnits/> The centre car includes the Group’s Group's main bar facility, called 'The Travelling Tavern', which was fitted in 2009. <gallery mode=packed heights=150px style="text-align:left">File: 59250_20150718.jpg | TSL NE59250</gallery>

A fourth car, '''DMBS M5193551935''', was purchased in June 1992 as a source of spares, but by 1993 winter of 1996 had been restored and entered service.<ref name=OurUnits/>

In autumn 1996 the The Group then acquired a fifth car, unpowered '''DTCL 56208 which arrived on 21 December''', giving an additional 65 seats capacity. 56208 was withdrawn from BR service in March 1993 and was first preserved at the Caerphilly Railway Centre. Following the closure of the centre it was transferred to DMU, arriving on 21 December1996. The vehicle was repainted into BR green and entered service in July 1997. 56208 was normally operated as trailer car for 51935 in a 2-car set, although it can run with either of the group's (DMBS) power cars.<ref name=OurUnits/> <gallery mode=packed heights=150px style="text-align:left">File: 56208_20150718.jpg | DTCL E56208</gallery>

In 2004, all five cars took part in the [[Railcar50]] event, participating in a 12 -car special which was the longest DMU formation ever to operate in preservation<ref name="prc"/>.

M51935 was extensively damaged by fire in May April 2008 in what was believed to be an arson attack. Subsequently The Group acquired '''DMBS 50933''' as a replacement. 50933 had been preserved by a private individual in 1993 at Peak Rail and purchased by the Dean Forest DMU Group in 2008 when the Peak Rail fleet was disbanded. However it was effectively surplus to their requirements and arrived on the SVR, initially on loan. After 51935 was confirmed as beyond economic repair, 50933 was sold to the DMU Group, becoming a permanent resident. Following an extensive mechanical overhaul, 50933 entered regular service in July 2009. 51935 subsequently left the SVR to be broken for spares elsewhere. The Group acquired <ref name=OurUnits/> <gallery mode=packed heights=150px style="text-align:left">File:50933_20150614.jpg | DMBS M50933 as a replacement. </gallery> In 2010 alterations were made for the [[:Category: Wheelchair-accessible adapted carriages|conveyance of wheelchair passengers]].

The DMU group has used Peak Rail and the SVR's Bewdley and Kidderminster workshops for contract overhauls, while undertaking maintenance itself at Bewdley. For much of 2018 and 2019 the DMU was unavailable for service for attention to various mechanical and electrical issues. It then being the only diesel -powered train capable of providing a heated train on the SVR, a mixture of steam and [[Diesel Locomotives hired by the SVR|hired-in diesel]] locomotives deputised for the winter services and the summer Scenic Cruises.

In 2022 the owning group commissioned a third-party engineer to produce a report detailing repairs and maintenance work required in order to return the DMU to traffic on the SVR. Chief among the work necessary was overhaul of the bogies. The group determined that an external contractor would carry out further bogie overhauls, with the intention of initially returning 52064 and 51941 to traffic as a twin power car set.<ref>[https://www.svrlive.com/bloct22 Branch Lines October 2022]</ref> As a result, 51941 was placed on accommodation bogies and its own sent for contract overhaul at the North Yorkshire Moors Railway workshops, while the car had repairs to the roof and remedial works to the rather tired paintwork at Kidderminster Carriage Shed.<ref>[https://www.svr-dmu.org.uk/ The DMU Group (West Midlands) website] (Retrieved 23 June 2023)</ref> The two-car set returned to traffic in December 2023, with TSL M59250 joining in . In February 2024 centre car E59250 was also returned to traffic to make a three car DMU.This was stationed at [[Bridgnorth]], rather than its normal base at [[Bewdley]], to provide a daily service starting at the north end of the line during half term operations while work was in progress on the second phase of the [[Bridgnorth MPD|Bridgnorth yard relay]].
