Some were physically converted to 1,435 mm (4 ft 8+1⁄2 in) standard gauge (the latest one the line between Berga and Kalmar in the 1970s) and some remain as heritage railways.
Southern Sweden had a small 1,067 mm (3 ft 6 in) network, reaching for example Halmstad, Växjö, Torsås, Karlskrona, Ronneby, Karlshamn, and Kristianstad.
The western one covered much of the province of Västergötland, from Gothenburg in the southwest to Hjo in the east and Gullspång in the north.
The eastern network covered much of the provinces of Småland and Östergötland, stretching from Växjö and Torsås in the south to Örebro in the north.
There were also smaller 891 mm (2 ft 11+3⁄32 in) networks on Gotland and in Uppland, as well as separate lines in other regions, among them Öland.
