rdf:langString NSB Class 88 was a class of six three-car diesel-hydraulic multiple units built by Strømmens Værksted for the Norwegian State Railways. Derived from the German DRG Class SVT 877, the trains were the diesel counterpart of Class 66. The trains were built as express trains on the Bergen Line and the Dovre Line, serving the routes from Oslo to Bergen and Trondheim. The first four units were delivered in 1945 and 1946, but mechanical failures caused them to highly unreliable until 1950. Two more units were delivered in 1958. Retirement started in 1963 and from 1965 the trains were moved to the Røros Line. They left regular service from 1970 and were chopped three years later. Each motor car had one powered bogie which was powered by a Maybach V12 prime mover rated at 900 kilowatts (1,200 hp), allowing the trains to each 120 km/h (75 mph) via a Voith hydraulic transmission. The trains were 67.57 meters (221.7 ft) long overall, weighing 113 tonnes (111 long tons; 125 short tons). They had space for 145 passengers, and included a saloon, kitchen and cargo room.
