The Stockholm Underground is a rapid transit system in Stockholm, Sweden. The first line opened in 1950, and today the system has 100 stations in use, of which 47 are underground and 53 above ground. There are three coloured main lines on the tube maps. These do however form seven actual routes with different termini. Routes numbered 17, 18 and 19 belonging to the green main line, 13 and 14 red main line and 10 and 11 blue main line all go through Stockholm City Centre in a very centralized metro system. All seven actual lines use The T-Centralen hub station. Apart from this central station for the metro, there exists just one other junction, the Fridhemsplan station, although both the green and red lines are mutually accessible at the Slussen and Gamla Stan stations.
