NHJ / NSB 0-6-0 Locomotives in Norway


Class Details by Steve Llanso of Sweat House Media

Class Class 42 (Locobase 6181)

Data from:

Svein Sando's Railway Site [link] (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).

Built originally for the NHJ (the Norwegian Trunk Line), later reclassed by the NSB and retired only on 4 July 1962.


Class Class 43 (Locobase 6182)

Data from:

Svein Sando's Railway Site [link] (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).

Built originally for the NHJ (the Norwegian Trunk Line) as immediate follow-ons to the 90. They were bigger in all respects, although still not more than modestly proportioned. This trio was reclassed by the NSB in 1926 and retired only on 17 July 1964.


Class E / Class 25e (Locobase 4076)

Originally built for the Swiss railways, these 5 engines came to the NSB in 1947. As the data show, they were very similar to the Class 25s already in Norwegian service. Norwegian Railway Club (Norsk Jerbaneklubb) website [link] . Data also from:
