The NSB Class 49, nicknamed Dovregubben ("the Dovre Giant"), locomotives were
The engines came in three series, the 49a, 49b and 49c. Between 1935 and 1941 five engines were produced by Hamar & Thune, two by Krupp AG.[1] In addition to the seven engines delivered, there were seven engines which were destroyed by a bombing raid during World War II while under construction in Germany, another four were under construction at Thune but were never completed. The engines were retired from service during 1957, stored and finally written off on December 16, 1958, due to dieselization of the Dovre Line.
The numbers of the Dovregubben locomotives were 463, 464, 465, 470, 471, 472 and 473. Engine no. 470 is on display at the Norwegian Railway Museum in Hamar.
