The DB Class V 60 is a German diesel locomotive operated by the Deutsche Bundesbahn (DB) and later, the Deutsche Bahn AG (DB AG), which is used particularly for shunting duties, but also for hauling light goods trains. Seventeen locomotives were bought used by the Norwegian State Railways and designated NSB Di 5. Also the Yugoslav Railways bought used units, and designated them JŽ 734; they were subsequently designated Series 2133 by the Croatian Railways.
The DB had a shortage of small shunters. As a result, in 1951, a diesel shunter was designed, almost all the major locomotive firms being involved in its development and production. The new class was initially called the V 60. In 1955 the first prototype locomotives, V 60 001–004, were delivered by Krupp, Krauss-Maffei, Mak and Henschel, each having different engines. Later that same year orders for the first production locomotives were issued; they were to have GTO 6 or GTO 6A motors from Maybach. Several of the locomotives were given a stronger frame and had a higher adhesive weight of 53 tonnes (52 long tons; 58 short tons) instead of 48.3–49.5 tonnes (47.5–48.7 long tons; 53.2–54.6 short tons). In addition these engines could carry up to an extra 6 tonnes (5.9 long tons; 6.6 short tons) of ballast for heavy duties, however they continued to be classed as V 60s. A total of 942 locomotives of this class were built. In 1968 the V 60s, like all other DB locomotives were given computer readable numbers. At this point the class was divided into Classes 260 (light variant) and 261 (heavy variant).
In the 1980s, the Norwegian State Railways (NSB) saw a need for shunters to replace the aging Di 2 units and chose to buy seven used V 260 from DB in 1985 and given the designation NSB Di 5. Two years later NSB bought another ten units, but one of them was only used for spare parts. The locomotives were numbered 5.861–877. They were scrapped between 1996 and 1998—none have been preserved.
