==DMU Group vehicles==
The [[The DMU Group (West Midlands) | DMU group]] operates five cars. These can be used as separate three car and two car units, but are usually combined to form a five car unit for purposes such as the summer Scenic Cruises. From time to time maintenance requirements may result in operation as a four car unit.
The first 2 cars, DMBS M51941 and DMCL M52064 arrived on the SVR from Doncaster via Tyseley on 30 March 1990, initially on a two year loan. 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 DMU Group.<ref>SVR News 102</ref>
Unpowered centre car TSL M59250 arrived on 7 June 1992 and entered service in November of that year to form a 3-car unit. The centre car includes the Group’s main bar facility, called 'The Travelling Tavern'.
A fourth car, DMBS M51935, was purchased in June 1992 as a source of spares, but by 1993 had been restored and entered service.
In autumn 1996 the Group acquired a fifth car, unpowered DTCL 56208 which arrived on 21 December, giving an additional 65 seats capacity.
M51935 was extensively damaged by fire in May 2008 in what was believed to be an arson attack. Subsequently it left the SVR to be broken for spares elsewhere. The Group acquired DMBS M50933 as a replacement. In 2010 alterations were made for the conveyance of wheelchair passengers.
==Workings in preservation==
*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>http://preserved.railcar.co.uk/</ref>.
*For much of 2018 and 2019 the DMU was unavailable for service for attention to various mechanical and electrical issues. It 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.
*By June 2019 all five vehicles were out of service due to considerable repairs needed on some of the bogies and brakegear, and the SVR mandating the units could not run. The repairs required the units to go to either the [[Carriage Repair Works|carriage repair works]] or [[Diesel Depot|diesel depot]] as the group lacked the resources and manpower to lift the vehicles.<ref>[https://dmuwmbsb.wordpress.com/2019/06/05/2019-maintenance-statement/ DMU Blue Square blog, 5 June 2019] (Retrieved 9 November 2020)</ref><ref>SVR News207</ref> In the event repairs fell to the carriage repair team, where it was held up by other work and [[2020 coronavirus disease (COVID-19) pandemic|COVID-19 restrictions]].
