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.
