Abstract
The present invention relates to a method of manufacturing an all metal, single or dual, flanged composite railroad wheel for rollingly engaging a metal rail. A unitary metal railroad wheel having at least one radially extending wheel flange, for intermittently engaging the side surface of the rail, is provided with a metallic inlaid material having a coefficient of friction lower than the coefficient of friction of the wheel's main body. The inlaid low friction material forms an annular band circumscribing the inside surface of the wheel's radially extending flange.
