The subway system, known as T-banan (Tunnelbanan, with stations marked by a blue-on-white "T"), is the easiest and fastest way to get around. Servicing more than 100 stations and covering more than 96 km (60 miles) of track, trains run frequently between 5 am and 3 am. In 2000 the subway system was bought from SL by Connex, the same company that runs the subways in Paris and London. Tickets for Stockholm subways and buses are interchangeable. Maps and timetables for all city transportation networks are available from the SL information desks at Sergels Torg, the central station, Slussen, and online.
