The delivery of the Di 2 stretched between 1954 and 1973 in two series. Series 1 consisted of six units built by MaK in Kiel, Germany in 1954 and 1957 and two units by Thune in Oslo. All the eight first locomotives had a six-cylinder MaK engine producing 423 kilowatts (567 horsepower).
NSB wanted more diesel-powered shunters so Bergen Diesel/Bergen Mekaniske Verksted developed a slightly more powerful diesel engine for the purpose, the type LT 6 producing 441 kilowatts (591 horsepower). Thune started delivery of the Series 2 with BMV engines in 1961 and started delivering a further batch in 1973, in total 46 engines in the second series.
At first the Di 2 engines were painted green, but later when NSB chose to paint its entire fleet red, the Di 2 engines were also converted to red. In the 1980s the Di 2 units were painted the distinct red and yellow shunter colors of NSB. Di 2 854 was in 1997 rebuilt in the Netherlands to Skd 225 with a new Caterpillar engine and driver's cab.
Two engines are today in use for the emergency train for Romeriksporten.
