The present work contains a survey of the transition of railway rails from 1901, when the first rail was produced in Japan, to the present and it also provides a description of the present-day status of rails for railways. At present, a total of more than 500,000 tons of rails per year are produced in Japan at the Yahata Iron Works of Nippon Steel Corporation and the Fukuyama Iron Works of Nippon Kokan Kabushiki Kaisha. These iron works produce such varieties of rails as 60-kg/m-50 m rails, hyper-hardened-head rails having improved resistance to wear and improved resistance to contact pressure, and rails with head flanges strengthened by heat treatment, representing a strengthening of the rail edge, which has a structural weakness. This study points out that it will be necessary for the future production of rails to employ such techniques as vacuum degassing and continuous casting of blooms as well as introducing alloy steels.
