Sweden is a country with a lot of trains - and very different trains. In addition to the onetime state monopoly Statens Järnvägar SJ, there are nowadays ca. 30 private railroad operators in the country, many of these owned or partly owned by local authorities of the regions (Länstrafiken companies). SJ is however still strong in long distance and regional passenger services. Track maintenance is no more part of SJ itself and is often handled by foreign companies and also the former SJ Cargo has been renamed Green Cargo and operates now as a company of its own.

Värmlandstrafiken is an example of the many regional operators partly or wholly owned by the local regional municipalities, the so called Lä:nstrafiken companies.
