Gällivare is the northern terminus of the Inlandsbanan — the 1,288 km "Inland Railway" that runs from Mora in Dalarna up through the Swedish wilderness to here. It is one of the great train journeys in Europe: lakes, forest, reindeer crossings, and the crossing of the Arctic Circle at Jokkmokk where the train stops so passengers can step off and have a ceremonial drink. The trip takes two days each way in summer with an overnight stop in Östersund.
The station also sits on the standard SJ network — the night train to Stockholm leaves from here, taking about 17 hours — and on the Malmbanan line east to Luleå and west to Narvik, the route by which the Lapland iron ore goes to the sea.
