In Sweden, since 1930-1940:s, 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. (comfortable when they are moved to the workshop for servicing, or at war, easily moved to secret location) The facility was built in 1960.
The plant on the images was decommissioned in 1995 when the railroad was moved further away, the future status/plan is unknown. Have tried to visit the plant for years, always closed, but recently it was open when I passed by
