DIOC / NSB 0-6-0 Locomotives in Norway


Class Details by Steve Llanso of Sweat House Media

Class Class 53 (Locobase 6197)

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). Wheelbase from Locomotive Magazine (4 April 1903), p.241.

Jernbane doesn't say when the NSB took over these saddle-tankers from the Dunderland Iron Ore Company, but the later of the two engines retired on 7 November 1955.
