How thick are rail elastic pads

Rail pads can prevent rail sleeper abrasion and the crushing of the sleeper under the rail foot. Rubber rail pads are normally designed to a specified load-deflection characteristic. The initial stiffness of the rail pad is designed to be low so that that their deformations under the springs toe loads is quite substantial.

Rail pad is a kind of rail fasteners used between the rails and the tie plate, and it is usually made of elastic polyurethane mat. It is usually used under the rails and above the tie plate. Rubber rail pad can buffer the shake that the vehicles pushed on the tie plate and protect the tie plate and the sleeper from abrasion and impaction and prolong the service life of other fasteners.

Our standard rail pads are made of rubber and are 4.5 mm to 10 mm thick. In addition to the basic rail pad properties, the standard rubber rail pad is usually designed for specific load deflection characteristics, which are certified in specifications such as SNCF IG04045 and DB 918 235.

Rail pad functions

A rail rubber pad is essential in reducing shock and vibration in a rail system. The pad laid under the rail to ensure:

• Load distribution over a larger surface

• Elimination of load concentration and the resultant fatigue stresses

• Centering of loads on the supporting element

• Absorption of uneven contact surfaces between rail and support

• Reduction of noise and vibration

• Sealing between the bottom of the rail and the top of the support

• Reduction of wear of the rail and its support
