DIOC / NSB 0-4-0 Locomotives in Norway
Class Details by Steve Llanso of Sweat House Media
Class Class 56 (Locobase 6200)
Data from:
Svein Sando's Railway Site [
] (9 June 2004)--(Later link: The Semaphore, accessed for link update 10 July 2022.)-- and the Jernbane (Iron Road) site http://jernbane.net (June 2004).
The Dunderland Iron Ore Company took delivery of these 4 saddle-tankers from Thune (B1 & B2) and Hamar (B3 & B4). In the world of Norwegian 2-axle tanks, these were the largest.
At the other end of their career line, the last was retired from the NSB on 11 May 1955
