NSB Class 71
high-speed train type operating in Norway
NSB Class 71 (Norwegian: type 71) is an electric multiple unit used by Flytoget for the Airport Express Trains on the Gardermoen Line of Norway. Sixteen three-car train sets were built by Adtranz Strømmen between 1997 and 1998. The units are capable of 210 km/h (130 mph), connecting Oslo Central Station and other stations in Metropolitan Oslo to the Oslo Airport, Gardermoen, along Norway's only high-speed railway.
In a three-car configuration, the units weigh 158 tonnes (156 long tons; 174 short tons) and are 82.3 metres (270 ft 0 in) long, with a power output of 2,645 kW (3,547 hp). The units are similar to the NSB Class 73, and are related to the Swedish X2 units. By 2009, all units were expanded with a fourth car.
Specifications
The unit is based on the Swedish X2 designed by Kalmar Verkstad in the 1980s, and delivered from 1990 to the Swedish State Railways for use in their X 2000 high-speed intercity trains. Although the technology involved is similar, like spot-welded stainless steel car bodies, the Class 71 differs in several ways. First, the unit does not have a separate locomotive unit, but has the motors spread throughout the train, with one powered and one unpowered bogie in each car. The car bodies are totally different in layout, including the doors between bogies instead of at the end of the cars.

Why this record matters
The phrase “high-speed train type operating in Norway” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 4, 2025. The linked authority identifier is Q172791. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1997, 1998, 2009 and 1990.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
