In addition to tests in Sweden, the X2 was tried out on the Randsfjord Line on 12 March 1993. The order for the units was placed on 23 February 1995, after NSB had received bids from ABB (that later merged with Daimler-Benz's train division to become Adtranz), AEG, Fiat Ferroviaria, Talbot, Linke-Hofmann-Busch, Siemens and Görlitz. During 1996, an X2 train was hired to test out performance on the Norwegian railway system, and for a short period put into service on the Sørland Line. The first Class 71 unit was delivered on 19 September 1997, and the last on 30 January 1998. The last unit, no. 71.16, was delivered with tilting mechanism to be used to test performance on the Norwegian railways, due to the similarities between Class 71 and Class 73. It could be seen during the winter on the challenging Bergen Line and Dovre Line. After a few years the tilting mechanism was removed.
