SJ F

The SJ Class F is an electric locomotive used by Swedish State Railways (Swedish: Statens Järnvägar, SJ) for hauling passenger trains. It was built in 24 copies by ASEA in 1942–49 and was in service to 1983.

History

In 1930 the Västra Stambanan line between Stockholm and Göteborg was improved so the top speed was increased to 120 kilometres per hour (75 mph). At the time SJ did not have locomotives that could reach that speed, so an intensive work was initiated to construct a fast locomotive in cooperation with ASEA. The alternatives were traditional wheel construction or the newer bogie technology. SJ chose the latter with wheel arrangement 1′Do1′, with four powered axles. Exterior wise the F series was very similar to the D-series.

The three test engines delivered in 1942 had different configurations of power transmission. After testing an additional 21 locomotives were delivered during the 1940s. They differed by only having two instead of three front windows, though the first three were later rebuilt.

SJ F (steam locomotive)

The F class was a type of steam locomotive used by Swedish State Railways (Swedish: Statens Järnvägar, SJ) and based on the Württemberg C. Eleven locos were built by Nydquist & Holm (NOHAB) between 1914 and 1916. It was primarily used on the main lines between Stockholm-Gothenburg and Stockholm-Malmö. It is one of the largest steam locomotives ever used in Sweden.

The superheated compound locomotive could produce 1,140 kilowatts (1,529 hp).

Denmark

During the 1930s the locomotives became obsolete due to electrification of the main lines, and in 1937 were sold to DSB of Denmark, where they served as DSB Class E DSB was so impressed with the performance of the E class that starting 1942, a further 25 locos were built by Frichs of Aarhus. The E class remained in service into the early 1970s. On the death of king Frederik IX the funeral train from Copenhagen to Roskilde on 14 January 1972 was double-headed by two class Es.

Preservation

Two of the Swedish-built locomotives are preserved and F 1200 is in running condition. Both are owned by the Swedish Railway Museum. Several Frichs-built locomotives are preserved in Denmark, and E 996 at Railworld in Peterborough. F 1200 was involved in a serious accident outside Getå in October 1918.
