The 49 class four-cylinder compound 2-8-4s of the Norwegian State Railways are the countrys most impressive and famous steam locomotives. Three were delivered by Thune and Hamar in 1935-36 for service on the Dovre line (the central section of the OsloTrondheim line) with its long 18 grades, two more from Krupp followed in 1940 and two from Thune in 1941. All were withdrawn in 1958, and one remains preserved will it run again? The locomotives were much celebrated at the time, but was it really a successful design? This matter is discussed in this new, expanded edition of a book first published in 1991. New material and photographs have come forward. 120 pages 23x21 cm, Norwegian text with a five-page summary in English, many photographs (some in colour), hb.
