Sweden once had some fairly extensive narrow-gauge networks, but most narrow-gauge railways are now closed. Some were physically converted to (the latest one the line between Berga and Kalmar in the 1970s) and some remain as heritage railways. The most common narrow gauge, (3 Swedish feet), exists only in Sweden. A smaller gauge network existed, and gauge was used mostly by smaller, industrial railways. Still other but lesser used gauges in the country were , , , and , all converted or removed.

This unique gauge was created by a measure mistake. It was planned to be 3 ft 6 in (3 ft 7 in with Swedish units) but became 3 ft 7 in English units.
Southern Sweden had a small network, reaching for example Halmstad, Växjö, TorsÃÂ¥s, Karlskrona, Ronneby, Karlshamn, and Kristianstad. As most of the railways in the province of Blekinge had this gauge, it was nicknamed "Blekinge gauge" in Sweden. All track is either demolished or rebuilt to .
A few smaller lines also had this gauge:
891 mm is equal to three Swedish feet.
Two large networks existed, separated by lake Vättern. The western one covered much of the province of Västergötland, from Gothenburg in the southwest to Hjo in the east and GullspÃÂ¥ng in the north. The eastern network covered much of the provinces of SmÃÂ¥land and ÃÂstergötland, stretching from Växjö and TorsÃÂ¥s in the south to ÃÂrebro in the north. There were also smaller networks on Gotland and in Uppland, as well as separate lines in other regions, among them ÃÂland. Plans for connecting the two main networks were made but never fulfilled.
Some lines were converted to , while most lines have been dismantled. In the 21st century, only the Roslagsbanan commuter rail still functions as a commercial railway. There is also tourist or heritage traffic on some lines.
is equal to 2.7 Swedish feet.
Numerous gauge agricultural and industrial railways were built. Nowadays a few are in use as tourist railways with steam trains.
