VR (Finnish state railways)
The company operated a train ferry for railway freight wagons between Turku, Finland, and Stockholm, Sweden. Because the 1,524 mm (5 ft) track gauge of the Finnish railways (VR) is 89 mm (3.5 in) wider than the standard gauge of much of the rest of Europe (including Sweden), a special fleet of freight wagons with interchangeable bogies is used. 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. These operated twice-daily from Turku and Stockholm. Rail car traffic onboard ferries Turku-Stockholm have been closed down on 30 April 2012.
