For test purposes, a few class 110 locomotives were provided with a more powerful, 1,200 PS diesel engine in 1972. This was required so that the locomotives could also be used in express train traffic. Further components were also modified on the test locomotives. Due to the good test results, a total of almost 500 locomotives were converted to the more powerful class 112 in the Reichsbahnausbesserungswerk (State Railway Repair Works) Stendal.
