Pa is an
electric locomotive used by
Swedish State Railways (
Swedish: Statens Järnvägar, SJ) for hauling passenger trains on
Malmbanan. It was delivered by
ASEA in 1914-1915 and was in service until the 1950s. Malmbanan was the first electrified railway owned by the state (several private lines was already electrified) in Sweden, and SJ needed a fast locomotive to haul the passenger trains on the line. One of the units is preserved.
