Аннотация к книге "List of rail transport systems using third rail"

High Quality Content by WIKIPEDIA articles! Third rail railways predominantly operate in urban contexts. Notable exceptions are (or were) mainline electrics of the former Southern Region of British Railways and a few interurban railways in the US. In Europe top contact third rail tends to be limited to early electrified urban railways (the current conductor is normally left naked on top), contrary to North America where it usually has a protecting cover. Obviously considered safe enough, the covered top contact conductor also appeared at most North American systems built relatively recently. Modern European systems predominantly make use of bottom or side contact power rails.
