无缝线路虽然减少了线路经常维修的费用,但对短的线路或专用线并不都如此。美国《Camcar/Textpon》公司为解决这个问题研究了《Camrail》型钢轨螺栓连接接头。它和焊接接头类似,轨端不产生错动。螺栓直径限于标准轨轨端孔眼的尺寸为25.4mm,抗拉强度极限为116.6百万巴 Although the seamless line to reduce the cost of regular maintenance lines, but not for short lines or special lines. The United States “Camcar / Textpon” company to solve this problem studied “Camrail” rail bolt joints. It is similar to the welded joints, rail ends do not produce dislocation. The diameter of the bolt is limited to 25.4 mm for the standard rail end hole and the tensile strength limit is 116.6 million bar
