The Association of American Railroads, through the Electrical Section of the Engineering Division have had a committee investigating the relative corrosion of ferrous and non-ferrous alloys in smoky atmospheres ever since 1930. That committee made installations of various kinds of alloys in a freight terminal yard at Lamberts Point, Norfolk, and in a tunnel in Welch, West Virginia, both located on the N&W Railroad. These installations were subjected to steam locomotive exhaust and gasses, and in the case of the Lambert Point installation, to dampness and fog from the seacoast. A third installation of identical materials was made in one of the smoke stacks of a steam locomotive round house on the New Haven Railroad at Cedar Hill, Connecticut. All of these materials were exposed for more than five years, and were examined periodically throughout the exposure period, and reported to the Electrical Section, AAR. This article summarizes the work done by this committee, which was an attempt to find the most economical alloys to be used in rail- road overhead contact systems.
