Electric Railways
In Europe, electricity is normally generated as three-phase AC at 50 hertz. Five European countries, Germany, Austria, Switzerland, Norway and Sweden have standardised on single-phase AC at 15 kV 16⅔ Hz for railway electrification. Phase converters are, therefore, used to change both the phase and the frequency.

Famous quotes containing the words electric and/or railways:
“Wisdom is like electricity. There is no permanently wise man, but men capable of wisdom, who, being put into certain company, or other favorable conditions, become wise for a short time, as glasses rubbed acquire electric power for a while.”
—Ralph Waldo Emerson (1803–1882)
“There is nothing in machinery, there is nothing in embankments and railways and iron bridges and engineering devices to oblige them to be ugly. Ugliness is the measure of imperfection.”
—H.G. (Herbert George)
