The Deutsche Reichsbahn designated four-axle mainline diesel locomotives for medium service as the class V 100 (from 1970: class 110). Compared to the original class 110, class 108 had a flow reverse gear and an optimised motor with reduced power. Following the new purpose as a shunting locomotive, the boiler could also be omitted; instead, cooler groups and a preheater were installed.
The 751 class is a diesel-electric general-purpose locomotive. A total of 230 series locomotives were built for the CSD in the CKD works in Prague in the years spanning 1966 to 1971. The locomotive achieves a top speed of 100 km/h. The 6-cylinder engine with turbocharger produces 1,500 hp.
Their applications ranged from international express trains to passenger trains and from heavy freight trains to “collectors” (shunting freight trains). They were also found in the border stations of the surrounding states. The protruding structures under the front windows quickly earned it the nickname “Bardotka”, loosely named after Brigitte Bardot, the French actress.
