The VT 12⁵ is a former diesel multiple unit commissioned by the Deutsche Bundesbahn from 1953 onwards. It was commonly used with either two or three car configurations, using the VM 12 middle car and VS 12 driving van trailer. Three-car trains were usually made up of two motor units and one unpowered middle car. The trainsets were routinely made up from twelve driving cars, four control cars and 13 middle cars and used in city express services. The VT 12⁵ was used in regional traffic, with first and second class saloon seating. From 1968 the VT 12⁵ bore the EDV class number 612, the VT 12⁶ was redesignated as the Class 613. After initially operating from Cologne and Dortmund the DMUs were based for many years at the Hamburg-Altona railway depot and, from 1982, stationed at the Brunswick depot.
