T-Centralen - Stockholm Metro system
The very heart of the Stockholm Metro system is the T-Centralen. The name is Swedish for “The T-Centre,” and “T” is an abbreviation for “tunnelbana,” the Swedish word for “subway” or “underground.” It used to be named “Centralen” (“The Centre”), but it was often mistaken for the train station, and so on January 27, 1958 it underwent a name change.
It is the only station that connects all three lines. It is also located downtown and is the most busy subway station. On a normal day, over 200,000 passengers go to or from the station.
The station is a good connection for those who also need the Stockholm Central Station for the trains and the Cityterminalen bus terminal.
There are two stations which are connected by a long moving walkway that connects them on the mezzanine level.
The first station opened on November 24, 1957. Running through it are the green line (lines 17-19) which comes from Gamla Stan (the Old Town) and Höterget, and the red line (lines 13 and 14) which goes between Gamla Stan and Östermalmstorg. This station has two platforms which are at different ground levels. The upper level is 8.5 metres below ground level and is used by the northbound green and the southbound red lines. The lower level platform is at 14 metres below ground level and is used by the southbound green line and northbound red line.
The second station was opened on August 31, 1975. Running through it is the blue line (lines 10 and 11) which goes from the metro station in Kungsträdgården to Rådhuset. This station is 26–32 meters below ground and has just one platform.
