Download coordinates as: Electric railways in Sweden are powered from a single-phase AC supply of 15 kV at 16+2⁄3 Hz, as used in Germany, Austria and Switzerland.
This grid is fed by frequency converters and has no generation nor transmission lines from Norway, which uses the same traction current system.
The other pole to ground is also 16 kV, but with opposite polarity and runs along the track on the overhead wires until separation section.
Converter Stations, which also feed power into 132 kV single phase AC grid.
The railway on the Öresund bridge is fed with Danish standard voltage, 25 kV 50 Hz AC, along around 6 km within Swedish borders.
