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.
