The Mt. Newman Mining Company's ore-hauling railway in Australia began investigating track and vehicle performance after rail corrugation became serious when 50 million gross tons of traffic had traversed its line. Over 2,000 100-ton gondolas are used to make up 138-car trains, up to 10 of which are operated daily at speeds of up to 72 km/h. Climate is hot and dry. Curve wear takes place at the gauge corner on the high rail with head crushing on the low rail and long-pitch corrugations on the high rail. Information is given on the variation in vertical wheel loads in a single ore train, distribution of lading variation in the cars, and on rail head wear on unit-train railways in Australia, Brazil, Canada and the U.S.
