[0049] Examples:
[0050] The production specifications of a factory (bottom width×rail height×abdominal cavity width×waist thickness, size unit) are GB60 (150×176×97×16.5, mm),
[0051] UIC60 (150×172×89.5×16.5, mm),
[0052] 136RE(152.4×185.74×106.36×17.46, mm),
[0053] 115RE(139.7×168.3×96.84×15.88, mm),
[0054] GB75(150×192×104.4×20, mm)
[0055] The five kinds of rails are designed using the rail rolling method of the present invention, that is, the rolling process in the BD zone is designed according to GB60 as the standard, and the remaining four kinds of rails apply the same rolling process as the GB60 rail in the BD zone. Fully meet the requirements of the standard, the abdominal cavity is well filled, and at the same time, there are no folding defects in the leg-to-waist connection and head-to-waist connection.
