The DB Class 218 (before 1968 the DB Class V 164) are a class of 4 axle, diesel hydraulic locomotives acquired by the Deutsche Bundesbahn for use on main and secondary lines for both passenger and freight trains.
The class represents the final major revision of the DB V 160 family of locomotives; having the preferred features of the antecedent locomotives, including a hydrodynamic brake, and a single engine providing electrical train heating via a generator as well as tractive power. The class were also the most numerous of the family, providing the backbone of the Deutsche Bundesbahn's main-line diesel locomotive traction from the 1970s up to the reunification of Germany.
Despite being displaced from many workings by DMUs, electrification, and inherited DR Class 130s, as of 2009 a significant number of the class still remain active throughout Germany.
The locomotives of series 218 were the last of the V 160 family to be developed; the main new feature was the use of a single engine to provide tractive power as well as electrical train heating when required (via an attached generator), the simplification over the two engined DB Class 217 was preferred, and was made possible by the availability of a higher powered (~1840 kW) engine compared to the original DB Class V 160 (~1400 kW).
In 1966 an initial twelve prototype locomotives were ordered from Krupp by the DB, for which the V 164 numbering was given, the main order came after the change to a 'computer compatible' UIC numbering scheme (See DB locomotive classification) which gave the number 218 as the reporting code for this class of locomotives.
The main series of 398 machines was produced between 1971 and 1979, by Krupp, Henschel, Krauss-Maffei and MaK. Additionally the engine DB 215 112, after being badly damaged in 1975 was repaired to Class 218 specification, and renumbered 218 399.
