How to Choose Between Rail Iron Plate and Railway Rubber Pad?
Rail Tie Plate
Rail iron tie plate (also called sole plate, base plate) and elastic cushion are installed between the rails and the sleepers to disperse the longitudinal forces to the sleepers pushed by the rail and freight. Rail plates with shoulders can also bear the lateral force.
Rail tie plate helps to fix the rail and fastening system, protect the ties against being cut and keep the rail gauge in the right place. It is usually installed with rail bolts or spikes. There are single shoulder rail tie plate, double shoulder rail tie plate and hook twin tie plate according to different rail weights.
Specification of Rail Tie Plate
| Rail tie plate | Applicable condition | Processing way | Material |
| Singer shoulder tie plate | Rail weight 56lb~100lb |
casting, forging, rolling |
QT500-7 or QT450-10 (low carbon steel or high carbon steel by forging, and low carbon steel S275JR, Q235,etc. by rolling.) |
| Double shoulder tie plate | Rail weight ≥100lb |
||
| Hook twin tie plate | turnout |
Rail Rubber Pad
Railway rubber pad, also called elastic cushion, is used on concrete sleepers rather than on timber. It is used to reduce the fatigue cracking of the concrete ties. It can buffer the impact loads and insulate the rails from sleepers. Rail rubber pad, plastic sleeper bearing plate, cork rubber pad and wooden plate are common cushions, while rail rubber pad is superior in general performance. GNEE RAILWAY RAILWAY can supply rubber pads made from natural rubber, SBR, chloroprene rubber, HDPE and EVA.
Characteristics of rail rubber pad
