In 1972 the Deutsche Reichsbahn equipped three locomotives, class 110, with a 1,200 hp Diesel motor, which later has proven successful in the express train service. Just as
with other components, the DR adjusted the hydrodynamic transmission accordingly. Between 1981 and 1990, further conversions (on approximately 500 locomotives) to 1,200
hp (883 kW) in the Raw Stendal were made using the motors 12 KVD 18/21 AL-4 and AL-5. These locomotives were designated as Class 112.
