钢轨在动荷载作用下的波浪形挠曲、列车制动、列车运行阻力、钢轨温度变化、轨道几何状态不良都会产生线路爬行。防止线路爬行的措施是加强轨道中间扣件的扣压力和接头夹板的夹紧力，同时采用以防爬器和防爬支撑组成的防爬设备来共同抵抗钢轨爬行，还可以安装轨距杆或轨撑。

Rail's wave flexure under dynamic load, train braking, train running resistance, rail temperature change and bad track geometry condition line crawling cause line crawling. The measures to prevent line crawling are that strengthening crimping force of rail middle fastener and clamping force of rail joint plate, and adopting anti-creeping equipment that comprised of anti-creeper and anti-creeping support resist rail creep together, installing rail distance rod or rail brace can do it as well.
