SJ is a limited liability company owned by the Swedish state and is tasked with operating profitable passenger rail services, both independently and on behalf of national and regional traffic authorities.

SJ’s own rail services are primarily long-distance, comprising high-speed and night-train services as well as regional rail services between major cities in Sweden and the Scandinavian capitals. Tendered services mainly comprise shorter rail journeys for commuting to work or school within one county or region. One such example is SJ’s subsidiary, SJ Götalandståg, which is tasked with operating commuter and regional trains in Western Sweden.
