Stockholm Metro dates from 1950 and has built up to have three lines and 100 stations. It is known as Tunnelbana - literally ‘Tunnel Rail’. The three lines are coloured green, blue and red - the first two originally after the colour of the rolling stock normally employed on the line. The three lines all connect at T-Centralen, located at the Central (Mainline) Station.
The majority of the stations are decorated with artwork and many retain their natural granite bedrock finish. Many stations have inclined lifts - mini funicular railways - that parallel the escalators in their slope shafts which provide disabled access without the expense of separate vertical lifts.
Trains run left hand (as did road traffic until 1967). Some of the route was originally operated by trams until conversion to the Metro; the track is all standard gauge. The total length of the network is 105 km and around 7 million passengers are carried per week. There are plans for further extensions to the network, including a short new line, in the early 2020s.
