This article presents the results of examining pilot bainite steel railroad rails and their tests. It is shown that the set of properties typical of these rails is unreachable in standard perlite steel rails and includes a combination of high strength, hardness, ductility, and impact toughness. Bainite steel rails exhibit a better resistance to fatigue defect formation and a greater fracture toughness and, at the same time, increased contact-fatigue strength and reliability at low temperatures. Considering the demand for rails designed for use at high loads, complex track plan, and low temperatures on the railroads of the Eastern Testing Area and Northern Latitudinal Railway, bainite steel seems an expedient alloy for application.
