The railway turnout itself is a complex family. In the process of laying the turnout, according to the characteristics of the line, the appropriate railway turnout product can be selected. Of course, the quality of the railroad switch itself will affect its service life, and external conditions will also affect its service life. The application of rail gauge tie rod on railway switch has a good protective effect, which can prevent the longitudinal extension of steel rail and maintain the gauge.
In general, rail gauge tie rod is an intermediate insulation for ensuring the technical requirements of track insulation. The pulling force of the tow bar is used to prevent the rail from spreading out when the locomotive passes. The rails are fixed by tie rods so that the locomotive can pass smoothly and stably.
