• No advance booking: tickets are sold only at the ticket offices in Mariefred, Läggesta Nedre and Taxinge-Näsby (card or Swish), and the queue gets long, so arrive early
• Toilets at stations only, in Mariefred, Läggesta Nedre and Taxinge-Näsby; there are none on board
• Strollers in the freight wagon at the front or back of the train, folded or with the brake on, and out of reach during the trip

A volunteer-run museum railway that runs steam trains on 600 mm track, the narrowest gauge Sweden used for passenger traffic. Trains leave Mariefred for Läggesta Nedre, and on some days continue to Taxinge-Näsby. Kids can ride out on the open carriage platforms.

On Castles & Steam days, the train links Gripsholm Castle and Taxinge Castle, with the S/S Mariefred steamboat for the other leg.
