Transportation
The Swedish rail system is called SJ; it has slower-speed trains throughout the country and faster X2000 trains connecting the major cities. Connection by rail is possible to Norway and Denmark; connections to Finland are by bus, due to rail gauge differences. It's possible to take Silja and Viking Line boats from Stockholm to Helsinki (Finland), Rostock (Germany) or Mariehamn island. The Scandinavian Airlines System and other airlines provides access by air for longer trips.
