Stockholm Commuter Rail - Lines

Lines

Since December 2012, there are six lines in the Stockholm commuter rail system, twice that of the previous three. There are two long lines across the county which run through central Stockholm: line 35 runs from Nynäshamn in the southeast to Bålsta in the northwest, and line 36 connects Södertälje in the southwest with Märsta in the north. The shorter line 37 in the southwest connects Gnesta to Södertälje. Line 33 runs from Upplands Väsby in the northeast to Nynäshamn, while line 34 runs from Tumba to Kungsängen. Lines 33 and 34 were created to reduce the need for transfers if one intends to travel from southeast to northeast, southwest to northwest and vice versa. Line 38 runs from Uppsala C in the northeast to Älvsjö in the south via Stockholm Arlanda Airport and Stockholm C, with some trains continuing to Tumba. The branch to Uppsala C located after Upplands Väsby used by Line 38 utilises the existing infrastructure of the Arlanda Line and a part of the East Coast Line. The total track length of the system is 211 kilometers (131 mi).

Because of the short station platforms and the lack of passing loops on the single-track portion of the Nynäs railway south of Västerhaninge, a train change takes place in Västerhaninge, so that Västerhaninge-Nynäshamn is in reality its own line. Platform lengthening and the construction of passing loops are planned to be completed in the fall of 2008. However, the line will probably remain divided for some time, in order to sustain a higher level of punctuality in the more central parts of the network.

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 4½ minutes on the central parts. Line 37 and outer parts of line 35 are served less frequently, with up to two hours between trains on weekends.

Most trains stop at all intermediate stations, except a few trains during rush hours that skip some smaller stations. 269,000 passengers use Stockholm commuter trains on an ordinary weekday (counting connecting passengers double). This is almost half of the total number of train passengers in Sweden, the metro and trams not included.
