serviceable for both the passengers as well as for carrying goods. With such a major contribution of railways to the Indian economy, all the components and fittings required for the construction of the complete body, have their own significance. Many a manufacturing units of these components and fittings are continuously engaged in coming up with innovative products as per latest technology. One of the most important parts of a train is the overhead fittings which constitute the most important aspect of railways.
Overhead Fittings are also known as overhead lines or overhead wires. Before going into further details, it is important to know what is an overhead fitting or an overhead line. According to Wikipedia, Overhead lines are wires used to transmit electrical energy to trolley buses, trains and trams at a distance from the energy supply point. Overhead lines are used on the basis of one or two overhead wires situated above the railway tracks and raised to a high electrical potential by connection to feeder stations at regular intervals. These feeder stations derive electricity from high-voltage electrical grid. Electric trains receive electric current from overhead line system using several specialized devices such as Pantograph, Bow Collector or a Trolley Pole. These current collection devices are pressed against the underside of the lowest wire of an overhead line system known as acontact wire. The current collectors are electrically conductive, and allow current to flow through to the transformer of the train or tram, and back to the feeder station via the steel wheels and one or both running rails of the track.
It is a form of train that uses electric rail cars sometimes used in streets. The term Light Rail was coined in 1972 by the U.S. Urban Mass Transit Association (UMTA) to welcome the appearance of new streetcar transformations which were taking place in Europe and the United States. The history of light rail can be delineated from the horse drawn street railways or a horse car which was drawn using animals like horse. Here the term 'light' is used to describe the light load and fast movement rather than its physical weight. The American Public Authority defines light rail as: "An electric railway with a 'light volume' traffic capacity compared to heavy rail". Also light rails are much more affordable than heavy rails.
