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.
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 [] . Data also from:
