Transportation in Stockholm is convenient on the one hand and very expensive on the other hand. The public transportation system consists of a metro, suburban trains, buses, trams and ferries. Especially the latter are a specialty of Stockholm as the city is connected with dozens of islands in the vicinity. You should be aware that especially taxis are very expensive in Stockholm.
Sweden has a very decent system of regional and long distance trains. At Stockholm Central Station you may board trains to other cities in Sweden or even Copenhagen. Moreover, there are several regional trains available if you want to explore cities around Stockholm.
Last but not least, at Stockholm Central Station, passengers may interconnect between regional trains, commuter rail (called Stockholms pendeltåg) as well as buses and the metro.
The Stockholm Metro is the most important means of transport in Stockholm. It’s used by more than hundred thousand people each day and consists of three lines. 52 of the 100 stations are located underground, while especially the stations further away from the city center are at ground level.
Even though officially only having three lines (Blue, Red and Green), there are actually seven lines in total. The blue and the red line are divided into two lines each, while the green line is divided into three lines. The most important station of the Stockholm Metro is T-Centralen (Central Station Stockholm) which is the only station that serves as an interchange for all lines.
Metro lines in Stockholm:
In addition to the metro, there is also a system of tram lines in Stockholm. It consists of five lines which operate in different areas of the city. In contrast to other cities, Stockholm decided to open new tram lines in the past years. Tram line 22 was initially opened in 2000, but got extended recently. Tram line 7 was built up from the scratch, too.
There’s a slight difference between the tram lines as line 7N is only operating as a heritage tramline while line 21 is operated by light rail and though different to the normal trams operating on lines 7, 12 and 22. However, this doesn’t make any difference for passengers which can board either of the trams with the same tickets that may be used for buses or the metro!
Tram lines in Stockholm:
Even though the extensive network of the metro, tram lines as well as commuter trains already covers large parts of Stockholm quite well, there are several bus lines as well. Buses are very modern and easily accessible and especially operate in areas where no connection to neither metro nor trams is available. The ticket system for buses, trams and metro trains is the same in Stockholm. You may either buy paper tickets or travel cards or a so-called SL Access Card.
With the latter, you are granted discount on your ticket purchases. However, the initial investment is 100 SEK (~ 10.70 Euro / 11.80 US-Dollar). Be aware that Stockholm uses a zone system, making longer rides more expensive than shorter ones. Day tickets for all means of transport are available for 115 SEK (~ 12.30 Euro / 13.60 US-Dollar). Be aware that you may not be able to purchase tickets onboard a bus!
As taxi prices are not regulated in Sweden, you have to expect quite high costs for taking a taxi in Stockholm. All taxis in the city are equipped with taxi meters and are mostly very modern and convenient. The base fare usually is around 45 SEK (~ 4.80 Euro / 5.30 US-Dollar) and 12 SEK (~ 1.30 Euro / 1.40 US-Dollar) for every kilometer.
Out of rush hour taxis usually are a little cheaper, while taking a cab at night is more expensive. Moreover, most taxi companies charge surcharges for special locations like the airport, Skavsta or the Arlanda Express Station. A ride to Stockholm Arlanda Airport usually costs around 500 SEK (~ 53.50 Euro / 59 US-Dollar) one way.
Last but not least, transportation in Stockholm has a very special feature. Due to its special location, the city needs ferries to make connections available for those living on the islands nearby. Be aware that only Djurgårdsfärjan accepts SL Access Cards and other day passes you may have purchased for using other means of public transportation.
All ferries are operated by Waxholmsbolaget on a daily basis in summer, making it easy and convenient to visit several islands a day when spending time in Stockholm. Other special means of transport include city bikes and carriages for tourists.
