Trains in Sweden are operated by the government run company SJ and its subsidiaries. However, they do not have a monopoly; in some regions private companies run the railway system. The counties are in charge of ticketing and day to day operations and also own a small amount of the track. There is a large network which connects Sweden to its European neighbours. Stockholm has a metro system and Gothenburg a tram network.
Since 1967 Sweden has had right hand drive roads, which are among the safest in the world. Their motorway network is extensive and connects Sweden with Denmark.
Ports and harbours are important for Swedish commercial shipping and tourism with the main ports being Gothenburg, Malmo and Stockholm.
The main airports are also at Gothenburg, Malmo and Stockholm, linking Sweden with the rest of Europe and the world, but there are a total of 152 airports in Sweden.
