A wheel seat is adjacent the dust guard and is adapted to receive a railway wheel thereon. The axial center interior portion of the railway axle is generally hollow. The railway axle is comprised of a steel with specified alloy range, mechanical properties and is of specified internal and external dimensions to allow the axle to be formed in a forging operation and to be utilized in heavy haul railway freight car service.
