Siret is a town in Romania, Suceava County, 2 km close to the border with Ukraine, one of the main border passing points in the North of the country, having both a road border post and a rail connection.
The rail is on a standard gauge on the Romanian side and continues as a Russian-style broad gauge into Ukraine. Siret (actually a nearby village called Vadul Siret) is one of the few places in Romania which provides a gauge change equipment, allowing transportation without transfer.
