There is a 3-kilometer (1.9 mi) long section from Haparanda to Torneå, which is on the Finnish side of the Finland–Sweden border.
The line is the only Swedish railway to the Finnish border.The single track line was used exclusively by freight trains between 1992 and 2021, during which time it was necessary to use buses from Luleå to the Haparanda bus station, with onward connections to Kemi in Finland.
During World War II, the traffic was dense again since the Baltic Sea was not safe.
In 1986 a more direct route was built between Övermorjärv and Östra Flakaträsk, bypassing the Räktjärv station.

Passenger services restarted on the 1st of April 2021, including one weekday round trip to/from Umeå.
