Key Techniques for Rail Fastening System

Railway Fastening System consists of rail fastenings. Rail fastenings are utilized to connect railroad and railroad sleeper. The major purpose of rail fastening system would be repairing rail on the railroad sleeper.

The common rail fastenings contain Rail Spike with base plates over the tie, E-clip fixing, Pandrol Quick Clip fixing, pressure nozzle fastening, bolt fastening, tack joint and seats fastening steel spring-loaded rail in seat fastening.

For passenger railway line, comfort and reliability is major goal. Ballastless track laying not only refers to substructure, including bridge, tunnel and subgrade. The key techniques for rail fastening system are the necessary condition for railway operation.

The passenger railway generally adopt ballastless track requires better elasticity of rail fastening system compared to ballast track. Elasticity of rail fastening system can’t be increased without limit. Otherwise it will have influence on smoothness of rail. So Balance rigidity of Railway Fastener and rail safety is one of the key techniques for rail fastening system.

In accordance with requirement of course circuit, rail fastening system should have great insulation land at the dry-wet-cycle condition. So that vital methods for rail fastening system must boost water resistor.
