Stockholm Central Station is the largest railway station in Sweden and it is where you will arrive if you travel to Stockholm by train. The station was opened in 1871. Today the station is the largest travel centre in the Nordic region with over 250,000 visitors daily. It is also the busiest station on the Stockholm commuter rail system. The city bus terminal is connected to the station by underground walkway as is T-Centralen, the adjoining metro station.
Central station is divided into several sections. The northern part, with tracks 1 to 7, constitutes a terminus station for various railways. Tracks 1 to 2 are reserved for the Arlanda Express, while tracks 4 to 7 are used for long-distance and regional traffic and overnight traffic to the north. Tracks 10 to 19 in the western part of the station constitute a passing station for local commuter trains. Tracks 10 to 12 are mostly used for long-distance and regional trains to the south while tracks 17 to 19 are mostly used for long-distance and regional trains to the north. The commuter rail uses two platforms and tracks 13 to 16.
Stockholm Commuter Rail is an important part of the rail system. There are three lines; two long lines across Stockholm County which run through central Stockholm and a shorter route in the southwest. The total track length of the system is 200 kilometers. Trains operate every 30 minutes from 5 am to 1 am every day, with 15-minute intervals during the daytime. Additional trains during rush hours give an average of 7½ minutes intervals for many stations, and trains every 4 minutes in the central parts. There are 50 stations in the network.
Apart from the Metro and the commuter rail there are other urban and suburban railways. Two which the visitor may use are Pendeltåg a commuter rail line crossing the city north/south and with two branches on either side, and Saltsjöbanan a suburban railway, opened in 1893 and electrified in 1913, leaving from Slussen and serving the eastern suburbs.
At Central Station there is a locker service on the upper floor (on the way to platforms 1 to 10). They cost 40 SEK for a small locker and 50 SEK for a big one but they will not fit a large size suitcase. Payment is with coins only (5 and 10 SEK denominations) and next to the ones on the hallway, there's a change machine called "VÄXLARE".
There are two money exchange services on the upper floor of the station, by the main entrance/exit. There is also a toilet/shower service on the upper floor, on a hallway next to a flight of stairs. You can buy tickets in machines or in the office. Machines accept most credit cards.
