 This time could in many ways be described as Fredriksberg's industrial golden age.The town's population culminated during the epoch with about 2,000 inhabitants, and the economy was good.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 railway network between Hällefors, Hörken and Neva on Inlandsbanan.
