In Sweden, since 1930-1940s, large parts of the railroad system is powered by electricity, but it is not enough with 220/230 volts. The voltage on the incoming high-voltage wire is typically 220, 130, 70 or 50kV 3 phase.
This voltage is transformed down to 6.3 kV which is the supply voltage substations are intended. Transformation takes place either outside the substation, the power supplier in a transformer adjacent to, or in the sub-station, the usual procedure at the mountain stations this.
The plant on the images here has two tube for the arrangement of converters on railroad trailer, which was moved along the rail. The facility was built in two stages, one of which is reportedly built 1944-1945 and the second built in 1961-1962.
The plant on the images was decommissioned in 2000. After that the decay has been fast, probably due to copper thieves, the future status/plan is unknown.
Have tried to visit the plant for years, heard that "it is now open", but when I arrived there, it has been "closed", but recently it was open when I passed by
Some good pictures of a similar plant, when it was in operation, you can find in John Eklund Electric museum: John Eklunds Elektriska Museum
