Tramway and electrical power supply without overhead wires

The tramway (electrical) system is a cost- efficient, safe and fast way of passenger transport with the smallest environment pollution (in relation to other types of passenger land transport). As an integral part of the public transport, it is often used in city centres, and it is adjusted to transport needs by prolongation and extension of tracks. However, some city areas need tramway line without overhead wires and their accompanying infrastructure. Motivated by those requirements, producers of tramway vehicles have design new or introduce existing ways of power transmission to vehicle, but without overhead lines and posts to support them. The paper will present systems of wireless electricity transmission which have been applied or are currently in the phase of testing for application in tramway vehicles. With a short description of the working principles and technology, a comparison of particular “wireless” systems will be given, and their advantages and shortcomings will be pointed out. Also, a short review will be given on the possibility of introduction of that type of passenger transport in cities which do not have, and plan to introduce tramways in the public transport system.
