Product description

A third rail (also called "contact rail" or "conductor rail") is used in the third-rail system as the means of providing DC electrical power to a railway locomotive or train, through a semi-continuous rigid conductor placed alongside or between the rails of a railway track. It is typically used in mass transit or rapid transit systems.
Our third rail is manufactured from a highly conductive aluminum alloy and fitted with a stainless-steel wearing face for current collector shoes to run on. The stainless steel is welded securely to the aluminum and not fixed purely by mechanical means. It is available for top, under or side running applications. The system includes rails and auxiliary components such as insulated supports, bolted joints, ramps, cable terminals, expansion joints, mid-point anchors and protective covers.
Some advantages include the reduction of the clearance height of the tunnel, a longer service life, a high degree of reliability, simplified maintenance, a minimal effect on the urban landscape and an effective reduction on the overall metro investment.
