The axle loadings of contemporary unit trains and the disparity between the speeds of such freights and high-speed passenger trains produce problems of wear, crushing, metal flow and corrugation of curve rail, along with gauge widening and overturning under extreme lateral forces. These effects are being countered with rail lubricators, surface grinding, hardened and fully heat-treated rail, larger tie plates and use of additional spikes on curves. The approaches of several individual railroads are described and an extended description of the Santa Fe's study of improved rail fasteners is included.
