The SJ Class Ma is an electric locomotive used by Swedish State Railways (Swedish: Statens Järnvägar, SJ) and later other railways. 41 units were built by ASEA between 1953 and 1960. It is derived from the older Mg-series, but unlike its predecessor it is used for freight and passenger trains. It is also the longest used loco in Sweden.
