What is List of British Rail departmental multiple unit classes?
The 900 series classes were reserved for multiple units in departmental stock, most of which were converted from old passenger units. In broad terms, classes 930-935 were allocated to Southern Region multiple units (ex-200 and 400 series), 936 & 937 to other EMUs (ex-300 and 500 series) and 960 to other DMUs (ex-100 series). In recent years, this has been less rigidly adhered to. ==Diesel multiple units== *[[British Rail Class 901|Class 901]] (Test units, ex-[[British Rail Class 101|Class 101]]) *[[British Rail Class 930#Diesel Units|Class 930]] (Departmental SR DEMUs) *[[British Rail Class 950|Class 950]] (Purpose-built test unit, similar to [[British Rail Class 150|Class 150]]) *[[British Rail Class 951|Class 951]] (Sandite/De-icer units, ex-Classes [[British Rail Class 201|201]], [[British Rail Class 203|203]], [[British Rail Class 205|205]], and [[British Rail Class 207|207]]) *[[British Rail Class 960#Diesel Units|Class 960]] (Departmental DMUs) *[[British Rail MPV|Multi-Purpose Vehicle]] (Purpose-built departmental vehicles) ==Gas turbine multiple unit== * [[British Rail APT-E|APT-E]] (Experimental [[Advanced Passenger Train]] unit) ==Electric multiple units== The original use for the Southern Region (SR) classes are included in brackets; these designations have been less rigidly applied in recent years. *[[British Rail Class 910|Class 910]] (Test units, ex-[[British Rail Class 488|Class 488]]) *[[British Rail Class 445|Class 920]] (3-Pep prototype unit) *[[British Rail Class 930#Electric Units|Class 930]] (SR Sandite and de-icing units) *[[British Rail Class 931|Class 931]] (SR route learning and stores units) *[[British Rail Class 932|Class 932]] (SR research and tractor units) *[[British Rail Class 933|Class 933]] (SR mobile instruction units) *[[British Rail Class 445|Class 935]] (4Pep Research units) *[[British Rail Class 936|Class 936]] (Sandite units, ex-classes [[British Rail Class 311|311]] and [[British Rail Class 501|501]]) *[[British Rail Class 937|Class 937]] (Sandite units, ex-classes [[Br
