The Class 210 of the Deutsche Bundesbahn (DB) consisted, briefly, of a series of eight diesel locomotives, with a top speed of 160 km/h intended for operations on express trains. The locomotives were peculiar in that an additional gas turbine engine was able to provide extra power when needed. The additional turbine made it, at the time, the strongest four-axle German diesel locomotive. Another set of locomotives the Class 210.4 also had the '210' number, being rebuilt from DB Class 218s in the late 1990s for faster (160 km/h) express passenger operations.
