The Frövi Machine and Works Railway museum is located in Frövi, just north of Orebro in central Sweden. It has a large and eclectic collection of small industrial narrow gauge equipment covering 4 gauges and a operating line. There is an excellent website with almost daily updates (in Swedish, but well illustrated) following the restoration and maintainance of the collection here: http://frovi-maskin-bruksbanemuseum.blogspot.se
