NSB El 18 is a class of 22 electric locomotives built by Adtranz and Swiss Locomotive and Machine Works (SLM) for the Norwegian State Railways (NSB). The class is a modification of the Swiss Federal Railways Re 460 locomotive and built at Adtranz Strømmen in 1996 and 1997. The class remains the only mainline electric locomotive used by NSB, and is predominantly used on some intercity services and all night trains on the Bergen Line, Dovre Line and Sørland Line, as well as some regional trains.
The locomotives are 18.5 metres (61 ft) long and weigh 83 tonnes (82 long tons; 91 short tons). They have three-phase asynchronous motors with a maximum power output of 5,880 kilowatts (7,890 hp), giving a tractive effort of 275 kilonewtons (62,000 lbf) and a maximum speed of 200 km/h (120 mph). They have a Bo'Bo' wheel arrangement and regenerative brakes. The exterior was designed by Pininfarina and the cabs have pressurization. The units are numbered 2241 through 2262.
During the early 1990s, NSB was in need of new electric haulage for their passenger trains, as both classes El 11 and El 13 were in need of replacement.El 17, the latest purchase, had proved unreliable, and NSB wanted to remove them from mainline service. In 1993, Re 460 and EuroSprinter locomotives were tested in Norway, with the Re 460 being tested from 28 August through 8 October. NSB was satisfied with both units, and stated that it would be possible to increase the train weight on the intercity services from 700 to 800 t (690 to 790 long tons; 770 to 880 short tons). During the first half of 1994, NSB leased two Re 460s to have sufficient locomotives for operation during the 1994 Winter Olympics.
