The decision to build was finally taken in 1898. The railway came to Kiruna 15 October 1899 and the Swedish and Norwegian sections were joined 15 November 1902. For LKAB, the great expense almost led to bankruptcy in 1901, just after the ore mining at Kiirunavaara had started. King Oscar II only opened the railway line 14 July 1903, preferring summer over winter to travel north.
