Halmstad-NSssjö 4-8-0 Locomotives in Sweden
Class Details by Steve Llanso of Sweat House Media
Class G12/E9 (Locobase 20217)
Data from Litt-E9, one of a series of SJ locomotive diagrams archived by Anders Lundbing on [
], last accessed 10 June 2017. See also the Bergslagen Railway Society's page at , last accessed 2 June 2015. Works numbers were 1880-1882 in 1931, 2025-2027 in 1936.
These mixed-traffic locomotives were the first Swedish eight-coupleds to lead with a bogie. The 1936 trio trailed tenders carrying 6 tonnes (6.6 short tons) of coal and 17.5 cu m (4,308 US gallons) of water; they weighed 41,800 kg loaded. Taken onto the Statens Jarnvagar (SJ) roster in 1945, they continued operating on the HNJ until retired in 1957.
