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 ...
Trevor the Traction Engine is one of the non-railway characters featured in The Railway Series of children's books by the Rev. W. Awdry. Appearing in several of the books, the traction engine was originally 'saved from scrap' by The Vicar of Wellsworth with the help of Edward the Blue Engine .
While a pantograph is mainly used to power a railway traction unit, there are certain cases where it has a function other than traction: Mechanical measurements and tests of new catenary (with or without voltage), on a catenary and contact line inspection car; General power supply of a measuring car;
Parts of a rail system might use different voltages, with higher voltages in long runs between stations and lower voltages near stations where only slower operation is needed. A variant of the DC system is the AC series motor, also known as the universal motor, which is essentially the same device but operates on alternating current.
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.
By placing the opposed pairs of horizontal wheels at the ends of the locomotive, rather than close together, Hanscotte ensured that they were less likely to drop contact at small gaps in the central rail and so fail to maintain traction—on the Chemin de Fer du Puy-de-Dôme line narrow gaps in the centre rail were permitted at level crossings.

Iranian railway history goes back to 1887 when an approximately 20-km long railway between Tehran and Ray was established. After this time many short railways were constructed but the main railway, Trans-Iranian Railway , was started in 1927 and operated in 1938 by connecting the Persian Gulf to the Caspian Sea.
A traction substation, traction current converter plant, rectifier station or traction power substation (TPSS) is an electrical substation that converts electric power from the form provided by the electrical power industry for public utility service to an appropriate voltage, current type and frequency to supply railways, trams (streetcars) or ...
