The NSB Type 11 were locomotives with the wheel arrangement 1'C (2–6–0), which were built between 1891 and 1896 by Dübs and Company in Glasgow and Nylands mekaniske verksted in Oslo in twelve examples in different versions for Norwegian state railway. Three locomotives were rebuilt into the Type 15d and Type 15h series. In the early days, its main use was on goods trains.
History[]
The Type 11 was one of three series of steam locomotives that NSB procured at the same time in 1891 for use on lighter laid standard-gauge line. The series was intended for goods trains, while the Type 12 were intended for local trains and the Type 13 for long-distance passenger trains. Overall, the three locomotives nos. 64 to 66 were ordered first.
The three types of locomotives had many things in common and were designed in close cooperation between the State Railways Engine Manager Oxaal and Dübs and Company. The type 12 was a tank engine version of the Type 11. They had identical boilers and tenders.
After the first delivery, another three locomotives were ordered from Dübs. They were built as compounded steam locomotives, which were standard steam locomotive technology at the time of construction in 1893. The change in design increased the locomotive weight compared to 11a.
Unlike some other railway lines in Norway which were narrow gauge the Solørbanen and Gudbrandsdalsbanen north of Hamar were constructed as standard gauge, as so-called “lett normalsporet bane”.
Four locomotives were built in Norway by Nylands mekaniske verksted in Christiania, which is known as a shipyard. The workshop briefly tried its hand at building locomotives in the 1890s.
Like many other Norwegian saturated steam locomotives, the type 11 was built between 1890 and 1910, but some locomotives were not modernized until after the First World War.
