Abstract：The rail standard for highspeed railway and the rail production technology of four steel mills in China after the technological transformation were briefly introduced. Combined with the sampling observation results of the rail quality, the quality status of rail was analyzed by mathematical statistics in China. Furthermore, it was compared with rail imported from other countries with advanced technology in highspeed railway. The results show that the rail standards for highspeed railway between China and Europe are equivalent; the production technology and equipment of 4 steel mills in China have come up to the advanced world levels through the technological transformation; the inner and apparent quality of rails produced by our country are equal to imported rails. Aiming at the problems which come from the period of rail producing and using, the effective measures was suggested for improving the quality of rail to a higher level, such as reducing the fluctuation and range of chemical composition, optimizing the process of rolling and straightening, using coating which can prevent decarburization to reduce the depth of decarburization.
