Abstract

A conductor provides electrical connection passing through a rubber cushioned rail vehicle wheel having rubber elements in between a central metal wheel portion and an outer flanged metal wheel tire. Thus, a length of wire has a central conductor connection tag attached to the central wheel portion with U-shaped spring clips at each end straddling over and electrically connecting with an internal mating ridge on the tire extending between two spaced rubber elements separating the central portion and tire.
