These DB Class V 100 diesel locomotives were produced in the late 1950s by the Deutsche Bundesbahn for non-electrified branch lines as a replacement for steam locomotives. The V 100 class was built in three different variants. Decommissioned locomotives were also used in Austria by the Austrian Federal Railways during the 1990s and early 2000s, where they were registered as ÖBB Class 2048 Class V 100.10 / Class 211 The Class V 100.10 was a diesel locomotive for light passenger and goods traffic on branch lines. It was developed in 1956 by the Bundesbahn Central Office in Munich together with the engineering works, Maschinenbau Kiel (MaK), for the Deutsche Bundesbahn. In the late autumn of 1958 the first six trials engines were delivered. Numbers V 100 001 to 005 were fitted with an 809 kW (1,100 HP) motor, but number V 100 006 was given a 993 kW (1,350 HP) motor. The latter formed the basis for the V 100.20, later DB Class 212. Number V 100 007 was built by MaK as the seventh trial engine and tested in Sweden; it was sold in 1959 to the Deutsche Bundesbahn. In 1960, the prototype series, numbers 001 to 005 and 007 were renumbered to V 100 1001 to 1005 and 1007 in order to better distinguish them from the more powerful V 100 006. In 1961 the production series was started, the run lasting until 1963. As well as MaK, the firms of Deutz, Maschinenfabrik Esslingen, Henschel, Jung, Krauss-Maffei and Krupp were involved in building the locomotives. As part of the renumbering of locomotives by the Deutsche Bundesbahn in 1968, the V 100.10 was redesignated as DB Class 211. The Deutsche Bahn AG inherited the locomotives in 1994. After almost 40 years service the last engine was withdrawn in 2001. Class V 100.20 / Classes 212 and 213 The DB Class V 100.20 (later Class 212) is a more powerful variant of the V 100. It was based on the prototype V 100 006, which from 1960 was renumbered to V 100 2001. It went into series production in 1962 and, unlike the V 100.10 which was employed on branch line service, it was also intended for main line duties and ramps. Up to 1966 a total of 381 examples entered service. The Class 212 is 12.1 metres long (from no. 022: 12.3 m) and weighs 63 tonnes. Its top
