Different Materials for Railway Gauge RodsRailway gauge rods are widely used on railway switch section. The function of railway gauge rod is to prevent the longitudinal stretching of steel rail and keep the track distance. Railway gauge rod is used to link two steel rails together with one rod, which is used to improve the lateral stability of the rail and improve the track's ability to maintain rail track distance. In the railway system, lacking of railway gauge rod will lead to rail track gauge deviation, even worse cause serious railway accident, such as train derailment, train overturning and other unthinkable consequence.
Different Materials for Railway Gauge RodAccording to the material, railway gauge rods can be divided into common railway gauge rod and insulated railway gauge rod. The common railway gauge rod are generally set on the railway switch area at the turning point. The tensile force of railway gauge rod can prevent the steel rails from outward expanding. The middle insulation of insulated railway gauge rod ensures the technical requirements of insulated railway track. Some railway lines have track circuits, and insulated railway gauge rods can protect these circuits well. Compared with common railway gauge rod, insulated railway gauge rods are widely used in railway track circuit section, for its structure features, like rational design, simple structure and reliable performance. The connection of the insulated track rod is covered with an insulating coat. In addition, the ends of two railway gauge rods and the inner holes are all have devices for connecting with each other.
