* scanditrain.de[6]DSB class MZ was a series of 61 diesel-electric locomotives operated by Danske Statsbaner. They were built by NOHAB between 1967 and 1978 on licence from General Motors EMD with subcontractors Thrige-Titan (traction motors) and Frichs (chassis, bodywork) .
There were four series of the locomotive built, designated I - IV.
Twenty units became the property of Railion Denmark in 2001, sixteen units of the III series were exported to Australia in the late 2000s, as of 2010 owned by Independent Rail of Australia. As of 2010 most of the remainder of the class are divided between various Danish, Swedish and Norwegian companies.
In sweden the locomotives have received the designation TMZ.

Sub-series
MZ I
Ten units of the first series were built between 1967 and 1969, each costing DKK ~2.4 million.[2] One is kept by DSB Museum (MZ 1401),[7] while the rest were sold to various Swedish operators between 2002 and 2006 including three to Motala Verkstad, two to Svensk Tågteknik AB (STT), and single units to TÅGAB, Inlandsgods, BK Tåg and Three T AB.[2]
MZ II
Sixteen units of the second series were built in 1970. They have a similar appearance and many of the same characteristics as the I-series.[3]
Seven units became the property of Railion Denmark in 2001. Most locomotives were sold to various Swedish and Norwegian operators between 2003 and 2006 including two units each to BK Tåg, TÅGAB and the Norwegian National Rail Administration (Jernbaneverket), and single units to Motala Verkstad and Svensk Tågteknik AB.[3] Locomotive number MZ 1425 has been rented to Railiom between 2001 and 2003 and in 2004 was equipped with automatic coupling for the transportation of IC4 multiple unit trains.[8]
MZ III
Twenty units of the third series were built between 1972–1974 at a cost of DKK ~3.75million each. They have a slightly different appearance and were equipped with more powerful engines (20 cylinder version) and higher top speed.[4] The maximum hauled train weight is increased by 200 tonnes over the second series.[3][4]
Two units were sold to Comsa of Spain in 2004.[4] Sixteen units were exported to Australia between 2006 and 2008 for Lachlan Valley Rail Freight (LVRF),[4][9] and two units were sold to BLDX of Denmark in 2008.[4]
MZ IV
Fifteen units of the fourth series were built between 1977 and 1978. It has the same performance as III,[5] but a slightly different appearance (narrower front window[6]).
Two units were to TÅGAB of Sweden in 2006, the remainder have been in service with Railion Denmark since 2001.[5]
Preservation
MZ 1401 is part of the collection of the Danish Railway Museum (Danmarks Jernbanemuseum).[7]
