Swedish State Railways
This is part of the line is the heart of Ö.Sl.J. The line was originally the SJ standard gauge spur line from Läggesta to Mariefred, which the Swedish State Railways (SJ) operated until 1964 when the line was closed. Ö.Sl.J. took over the track and station in Mariefred after a few years and relaid the track to narrow gauge.
