O is a series of electric locomotives used by Swedish State Railways (Swedish: Statens Järnvägar, SJ) for hauling heavy iron ore trains on the Iron Ore Line in Sweden. The type Oa locomotives were built by Siemens and type Ob were built by ASEA.
History
The O series was built for the first
Siemens of Germany and ASEA. The Siemens locomotives were designated Oa while the ASEA locomotives were designated Ob. The trains had 1200 kW motors.[1]
These stayed in service on the northern section until 1923 when the southern section to Luleå also was electrified, at which time they were moved to the southern section. A new series of Oe and Of locomotives were delivered. In the 1950s when larger trains were put into service, some of the Ofs were rebuilt to triple units, designated Of3. They were also supplemented with the new Dm-series that eventually replaced them.
