Railway electrification as a means of traction emerged at the end of the nineteenth century, although experiments in electric rail have been traced back to the mid-nineteenth century. [1] Thomas Davenport , in Brandon, Vermont , erected a circular model railroad on which ran battery-powered locomotives (or locomotives running on battery-powered ...
Railway electrification is the development of powering trains and locomotives using electricity instead of diesel or steam power.The history of railway electrification dates back to the late 19th century when the first electric tramways were introduced in cities like Berlin, London, and New York City.
In 1897, Kandó designed an electric system and engines for the Italian railways, the electric traction system had great advantages and importance on the very steep railway tracks in the mountainous regions of Italy. Under his leadership, the Ganz factory began work on three-phase haulage for railways.
Automatic dropping device (ADD) is a safety device that automatically lowers the pantograph on electric trains to prevent accidents in case of obstructions or emergencies. [20] [21] It is also known as pantograph dropping device. [22] The automatic dropping device is obligatory for trains with operational speeds of 160 km/h and higher.
Italian railways were the first in the world to introduce electric traction for the entire length of a main line rather than just a short stretch. The 106 km Ferrovia della Valtellina line was opened on 4 September 1902, designed by Kandó and a team from the Ganz works. [51] [52] The electrical system was three-phase at 3 kV 15 Hz.
The generic term used by the International Union of Railways for the technology is overhead line. [1] It is known variously as overhead catenary, overhead contact line (OCL), overhead contact system (OCS), overhead equipment (OHE), overhead line equipment (OLE or OHLE), overhead lines (OHL), overhead wiring (OHW), traction wire, and trolley wire.
A railway pioneer is someone who has made a significant contribution to the historical development of the railway (US: railroad). This definition includes locomotive engineers, railway construction engineers, operators of railway companies, major railway investors and politicians, of national and international importance for the development of rail transport.
A traction network or traction power network is an electricity grid for the supply of electrified rail networks. The installation of a separate traction network generally is done only if the railway in question uses alternating current (AC) with a frequency lower than that of the national grid, such as in Germany, Austria and Switzerland.
