Class Details by Steve Llanso of Sweat House Media
Class Class 8 (Locobase 6141)
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).
Unusual proportions for the cylinder bore and stroke on these little tanks. 118 held on the longest, running until 20 October 1933.
