Traction power network

A traction power network is a electricity grid for the supply of electric trains. The installation of separate traction power network is generally only meaningful if the railway in question uses alternating current with a frequency lower than that of the national grid, like in Germany, Austria and Switzerland.

Alternatively, the three-phase alternating current of the power grid can converted in the substations of the railway by rotary transformers or static inverters into the voltage and type of current required by the trains. For railways which run on direct current, this method is always used, as well as for railways which run on single phase AC current of decreased frequency, as in Mecklenburg-Western Pomerania, Saxony-Anhalt, Norway and Sweden. In these areas there are no traction current lines.
