Rail transport in Norway

The Norwegian railway system comprises 4,087 km of standard gauge (1,435 mm) track of which 2,622 km is electrified and 219 km double track. There are 696 tunnels and 2760 bridges.

Jernbaneverket is a state owned agency which builds and maintains all railway tracks, while other companies operate them. These companies include Norges Statsbaner, NSB Anbud, CargoNet, Flytoget, Hector Rail, Tågåkeriet and Ofotbanen.

The first railway in Norway was Hovedbanen between Oslo and Eidsvoll and opened in 1854. The main purpose of the railway was to freight lumber from Mjøsa to the capital, but also passenger traffic was offered. In the period between the 1860s and the 1880s Norway saw a boom of smaller railways being built, including isolated railways in Central and Western Norway. The predominant gauge at the time was narrow gauge (1067 mm), but some lines were built in standard gauge (1435 mm). The height of the era came in 1877 when Rørosbanen connected Central Norway to the capital. In 1883 the entire main railway network was taken over by NSB, though a number of industrial railways and branch lines continued to be operated by private companies.

Three urban railways, in Oslo, Bergen and Trondheim, were started as horsecar systems between 1875 and 1893. They were all electrified around the turn of the century.
