NSB El 17
locomotive class
The NSB El 17 is a class of twelve electric locomotives built by Thyssen-Henschel and Norsk Elektrisk & Brown Boveri (NEBB) for the Norwegian State Railways (NSB). The class was built in two batches, the first delivered in 1982 and numbered 2221–2226, and the second delivered in 1987 and numbered 2227–2232. The traction system of the El 17 was based on the DB Class 120 of Germany (BBC, AEG and Siemens) and were among the first in the world to feature three-phase asynchronous motors. The units were ordered to be used on the intercity Bergen, Dovre and Sørland Lines, but were plagued with technical faults (overheating traction equipment, transient voltages, etc.). The unreliability and lack of sufficient power forced NSB to instead use them in the regional Vestfold and Gjøvik Lines. With the delivery of the El 18, the first series was retired or used as shunters. The second series has been used on the Flåm Line since 1998.
The locomotives have a maximum 3,000 kilowatts (4,000 hp) power output and a 240 kN (54,000 lbf) tractive effort, allowing the locomotive to haul a six-car train. They run on a 15 kV 16.7 Hz AC power supply and are capable of operating at 150 km/h (93 mph). The units have a Bo'Bo' wheel arrangement, have regenerative brakes and weigh 64 tonnes (63 long tons; 71 short tons).
This brief starts where responsible research should: with the source description of “NSB El 17” as locomotive class. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as locomotive class. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 21, 2025. The linked authority identifier is Q264669. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1982, 1987 and 1998.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
