Interaction Between Railway Elastic Clips And Rail Pad

Sep 04, 2025 Leave a message

Elastic rail clip is one of the common railway fasteners in the railway system. In general, elastic rail clip is made of forged spring steel and has many applications. No matter as a part of rail fastening system or as a rail fastener, elastic rail clip is used with other railway track parts, such as railroad spike, rail pad, tie plate and plastic dowel.

Products Description

 

Rail pads are made of rubber and are primarily used to protect railway sleepers from wear and impact. They are placed between the railroad ties and rails and are securely held together by railway clips. This configuration allows the rail pads and railway clip to provide important stiffness and support to the railway track structure, helping to ensure the stability and reliability of the railway system.
