1·Curve superelevation, critical transversal track resistance and gauge keeping strength are the principal parameters governing the passing speed of trains over the curve.
曲线超高、轨道临界横向抗力、轨距保持强度是控制列车曲线通过速度的主要参数。
2·The performance-to-price ratio superelevation, with the platoon "s price is alone to enjoy."
