DIOC / NSB 2-6-2 Locomotives in Norway
Class Details by Steve Llanso of Sweat House Media
Class Class 54 (Locobase 6198)
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 [] (June 2004).
Delivered to the Dunderland Iron Ore Company in the same year as the saddle-tanks, the little Prairie tanks survived long enough to be taken into the NSB. The last one retired on 5 November 1957
