The company operated a train ferry for railway freight wagons between Turku, Finland, and Stockholm, Sweden.

The break-of-gauge point is several hundred meters inside Finland at Turku and the bogies are exchanged in a specially-equipped depot; this procedure can be achieved in 10 minutes and involves jacking up each wagon.

The short section of 1,435 mm (4 ft 8+1⁄2 in) standard gauge track at Turku is sometimes known as "Little Sweden".

The Tallink train ferry Sea Wind conveys the SeaRail wagons between Finland and Sweden.

Rail car traffic onboard ferries from Turku to Stockholm were closed down on 30 April 2012.
