German Federal Railway class 210

As locomotives with pure turbine propulsion consumed too much, eight locomotives of the class 210 were built after the prototype V 169 001 from 1970. In principle, this was a class 218, whose 2,500 hp diesel was supplemented by a 1,150 hp turbine. This turbine needed little space, could burn the same diesel fuel and was switched on when heavy express trains had to be accelerated. The locomotives were used successfully between Munich and the Allgäu until 1978, when the first signs of fatigue appeared due to the frequent switching on and off. The turbines were then removed and the locomotives were redesignated as class 218⁹.
