The class MT was a class of diesel-electric locomotives of the Danish State Railways (DSB). Built by Danish manufacturer Frichs, the locomotives entered service in 1958–1960. They were primarily used for heavy shunting and branch line trains. A total of 17 units were built, numbered 151–167.

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]
