Since construction of the original track in 1966, track components have undergone continuous refinement. The original design did not anticipate today's high tonnage and involved theories and materials available at that time. All components from rail through fasteners and ties to the ballast have since been subjected to continuous heavy-axle-load unit train operation. Deficiencies in the original design have required many alterations and upgrading programs to cope with the problems encountered. The paper traces the history of Hamersley's track and indicates how it has been modified to handle an annual density of over 50 million gross tons.
