摘要：
It has been common practice to use heavy rails on heavy haul railways to reduce rail defects and track deterioration. The clear advantages of using heavy rails on high-speed railways are discussed in the paper. Since future rails should guarantee the dynamic stability of rolling stock and be free of rail defects, it is appropriate to consider modifying the wheel running band formed by rail grinding. The author therefore proposes the use of a new 75 kg rail profile with full use of grinding (designated ''75G rail'') which is developed based on experience in rail profile design in Japan. Mathematical equations have been applied to model the profile in place of drawing.
