NSB Class 71

The NSB Class 71 is an electric multiple unit used by Flytoget for the Airport Express Trains on the Gardermoen Line in Norway, the country's only high-speed railway. Sixteen three-car sets were built by Adtranz Strømmen in 1997 and 1998, the first delivered on 19 September 1997, and each has a power output of 2,645 kilowatts and a top speed of 210 kilometres per hour so that Oslo Central Station and the airport are under 20 minutes apart. The design is based on the Swedish X2 that Kalmar Verkstad designed in the 1980s but differs in having motors spread through the train, pressure tight cars, no tilting and a different nose. The order was placed on 23 February 1995 after bids from ABB, which later merged with Daimler-Benz's train division to become Adtranz, and from AEG, Fiat Ferroviaria, Siemens and others. The sixteen units cost 1.4 billion kroner, and Bombardier Transportation, which had bought ADtranz, built a fourth car for each unit from 2008 to raise capacity by 40 percent to 244 seats.
