Rail fastening system is composed of main parts of the rail structure for connecting steel rails with sleepers, also known as rail fastening parts. Rail fastening system functions by fixing the rail on the sleeper, maintain the gauge and prevent the rail from moving longitudinally and laterally relative to sleeper. And it provides enough elastics to make up for deficency of conceret sleeper.
GNEE RAILWAY RAILWAYL manufacture kinds of Railway Screw Spike, Clip and Clamp, High Tensile Bolt with Nut and Washer, Rail Base(Tie) Plate, Rail Fish Plate, Rail Shoulder, Rail anchor,Rail Screw and Spike, Fish Bolt with Nut and Washer, Rail Dowel, Rubber and EVA Pad, Crane Rail and Light Rail, and Other rail fasteners parts.
The selection of rail fastenings must take into account the following factors:
- track geometry
- permissible and enhanced permissible speeds
- track category
- loads arising from braking and acceleration of trains
- vehicle axle loads
- electrical insulation requirements
- underlying formation and structures supporting the track
- the form of track construction
