DSB Class MZ

Series MZ hot diesel locomotives with diesel-electric power transfer from the Danish State Railways. In four model series Electro-Motive Division (EMD ) were prepared a total of 61 specimens in the years 1967 to 1978 by the Swedish company NOHAB under license from General Motors.


General Motors took in 1964 with the powerful motor type 645, the highly successful previous version 567 from the market. NOHAB as a licensee was then forced to make changes with respect to the types MX and MY. The locomotive body was changed and stored the cabs floating. Also, the boiler was replaced with a generator for electric train heating.

The first two production groups were equipped with engines of 2426 kW ( 3300 hp) and had a maximum speed of 143 km / h In some publications, these two series are also grouped together due to the small differences in a. From the third production series engines came with 2867 kW ( 3900 hp) and the speed limit was raised to 165 km / h. The service weight of the locomotives is around 120 tonnes. This results in an axle load from 19.4 to 20.5 t.

The fourth type series has a different geometry of the car body. The side walls were made perpendicular to the top of the cab doors while the car body has already been drawn inwards with the older model series below. The cabs were a total square. The fourth type series can be easily recognized by the significantly lower level of their windshields.
