Roslagsbanan is an 891 mm (2 ft 11 1⁄10 in) (three Swedish feet) narrow gauge urban railway system in Roslagen, Stockholm County, Sweden. Its combined route length is 65 kilometres (40 miles) and there are 38 stations.
The line starts in Stockholm at Stockholm East Station (Stockholms östra station, Stockholm Ö). It goes north and splits into three branch lines at the junction stations Djursholms Ösby and Roslags Näsby; the three branches terminate at Näsbypark, Österskär and Kårsta.
It is double track between Stockholm and Viggbyholm and between Åkers Runö and Åkersberga. The rest is single track, but the line to Vallentuna was being doubled in 2012.
