Турнеэльвен
At the border with Sweden where the Torne river separates the cities of Tornio, Finland and Haparanda, Sweden, a two-kilometre section of dual gauge track uses a gauntlet configuration because the gauge used in Finland and used in Sweden are too close for a common rail to be shared. The link, which opened in 1919 with the completion of the Torne River Railway Bridge, is complemented by a marshalling yard at each end, an arrangement that allows trains from either country to stop in the other for freight to be transferred to trains of the local gauge.
