Zusammenfassung:The utility model relates to a novel structure of a high manganese steel frog point rail, which not only can reliably bear a huge alternating shock load of wheels, but also can ensure that the top surface of the rail is difficult to strip and chip. The novel structure comprises the high manganese steel frog point rail; the high manganese steel frog point rail is uniformly and gradually widened to 6mm from a place from 80 mm to an actual tip; and the obliquity of a working edge is gradually transited from 1:5 to 3:8. The utility model has the advantages that 1, the high manganese steel frog point rail structure is optimized, the contact form of the top surface of the point rail is improved, and the service life of a frog is prolonged; 2, the actual tip of the frog point rail is widened by 40 percent, so that effective contact area of the point rail is obviously enlarged, the strength of a small cross section of the point rail is enhanced, the wear resistance of the point rail is improved, and the whole service
