The original Frichs V8 diesel engines proved unreliable, and the locomotives were rebuilt with Maybach-Mercedes V12 engines during 1969–1971.[1]

The first class MT unit was retired in 1990 after a shunting accident, though the remaining locomotives were not retired from DSB service until 1997–2000. MT 166 remained in use as a service locomotive (tjenestelokomotiv) until 2006.[2]
