NMT has its operating base at Hønefoss Station in Ringerike, Norway.
[1] The society was founded on 22 May 1969, and is based at Bryn Station in Oslo, but with local groups all over the country.
All the members of NMT are volunteers and their classic train activities are under government supervision.
NMT is doing restoration, preservation and operation of classic trains at the 1,435 mm (4 ft 8+1⁄2 in) standard gauge part of the Norwegian railway network.
All income of the activity is solely used for the preservation of Norwegian railway history so that the coming generations will be allowed to experience and learn transport by train of the 19th and 20th centuries.
