Fredriksberg had already since 1875 a railway connection with Hörken on Bergslagsbanan (the so-called Säfsbanan), but came from 1931 (when a line to Hällefors was opened) to 1940 (when the line to Hörken was discontinued) to be the centre of the narrow gauge 802 mm railway network between Hällefors, Hörken and Neva on Inlandsbanan.
