The Saint Petersburg–Hiitola railway is a 170-kilometer (110 mi) long railway with 1,520 mm (4 ft 11+27⁄32 in) broad gauge located in St. Petersburg, Leningrad Oblast (Karelian Isthmus) and Republic of Karelia, which links Finlyandsky Rail Terminal to Khiytola (Finnish: Hiitola) through Devyatkino, Vaskelovo, Sosnovo, Priozersk and Kuznechnoye.

In spring 1918, troops under Georg Elfvengren blew up the track to prevent supplies reaching Red Guard units operating near Rautu.

[3][4] The railway was cut between Nuijala (67th km) and Lembolovo and 1.7 kilometres (1.1 mi) of track was removed on the Finnish side.

In June 1944 during the final stages of the Continuation War, a train of Karelian evacuees was bombed by the Soviet Air Force in Petäjärvi.

By 1930 in Finland a railroad linking Viipuri (Vyborg), Heinjoki (Veshchevo), Ristseppälä (Zhitkovo) and Valkjärvi (Michurinskoye) had been built, which was expected to be continued to Rautu (Sosnovo).

The Finns considered also to build this missing link but they found the difference in turns of highest maximum up grade too big (Valkjärvi station was 111.89 metres (367.1 ft) above sea level).

At Käkisalmi was a short industrial 1,524 mm (5 ft) broad gauge railway to the German-owned Waldhof Cellulose Factory.

As of 2007, projects are being discussed to construct a cargo railway along the northern shore of the Vuoksi River from Losevo to Kamennogorsk to ship crude oil to the sea port of Primorsk bypassing the Saint Petersburg – Vyborg line.

The railway is used to ship petroleum to the ports of the Gulf of Finland through Hiitola, lumber and iron ore pellets from Karelia, as well as granite rubble from Kuznechnoye.
