Statens Jarnvagar 0-6-0 Locomotives in Sweden


Class Details by Steve Llanso of Sweat House Media

Class Avesta (Locobase 3299)

Scale drawing on [] includes a short description. O&K works numbers were 10548-10550. This engine had the same dimensions as the earlier 0-4-0s, but had one more driving axle.

The Avesta went from logging sites to a chalk mine (where it didn't go into service) to an asphalt plant at Hallsberg (Nya Asfalt AB) to heat sand to Avesta Ironworks where it ran until 1962.


Class U (Locobase 9515)

Data from "Richmond Locomotive for Swedish State Railways," Railway and Locomotive Engineering, Volume 12, No 10 (October 1899), page 436. See also Tommy Nilsson's Svenska-lok website entry on the U class at [], last accessed 17 June 2018. Works numbers were 2841-2850 in 1899.

This decade of side tanks was built as a batch together with ten compound Ten-wheelers for service north of the Arctic Circle. As a sidelight, Locobase reproduces the list of accessory manufacturers involved in producing a relatively small locomotive, as noted by the article: "Nathan lubricators, United States metallic packing, Latrobe tires, French springs, Monitor injectors, Coale safety valves. Star steam gage and magnesia sectional boiler covering."

Tommy Nilsson's svenska-lok site describes the class as "robust" examples of locomotives built to North American standards because the need was too urgent to allow conversion to Swedish standards. After twenty years of service, two were retired and other eight sent to the Ostkustbanan. The last five were scrapped in 1933.
