Roslagsbanan

Roslagsbanan is a broad-gauge railway line in Roslagen, Sweden, north of Stockholm. It is part of the Stockholm public transport network, SL. The railway line is known for its distinctive red trains and its extensive network of branches. The first section of Roslagsbanan opened in 1884, connecting Stockholm to Rimbo. Over the years, the network expanded to serve many communities in the Roslagen region.

The current network consists of three main lines: Kårsta, Österskär, and Näsbypark. These lines diverge from the central station, Stockholm East Station. Roslagsbanan is a popular choice for commuters traveling into Stockholm and for tourists exploring the scenic Roslagen archipelago. The line is operated by Arriva Sverige AB on behalf of SL.

Plans for modernizing and extending Roslagsbanan have been in place for many years, aiming to improve capacity and service frequency. These include track upgrades, new rolling stock, and potential extensions to new areas. The railway plays a vital role in connecting the northern Stockholm suburbs and Roslagen to the capital city. Its historical significance combined with its ongoing development makes it a key piece of the region's transportation infrastructure.
