Railway electrification using alternating current at 15 kilovolts and 16.7 hertz are used on transport railways in Germany, Austria, Switzerland, Sweden, and Norway. The high voltage enables high powe
A pylon of a single-phase AC 110 kV power line near Bartholomä in Germany. Lines of this type are used in Germany to supply electric railways with single-phase AC at 16.7 hertz. In the substations of the railway, transformers are used to step it down to 15 kV.

Railway electrification systems using alternating current at 25 kilovolts are used worldwide, especially for high-speed rail. It is usually supplied at the standard utility frequency, which simplifies
15 kV AC railway electrification
…of the traction motors that were available at the beginning of the 20th century. Globally, railway electrification in late 20th century tends to use 25 kV, 50 Hz AC systems which has become the preferred standard for new railway electrifications. Nevertheless, local extensions of the existing 15 kV network is commonplace…
