Rail Pad Function in Railway Fastening System
Sep 22, 2025
The raid pad prevents 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, their deformations under the springs toe loads is quite substantial. This special design keeps the rail pad remains in intimate contact with the rail despite any vertical movements of the latter.

When the wheel is over the pad, the latter's stiffness must prevent large movements, so as to prevent metal spring becoming loose. Such a load-deflection characteristic can be obtained by introducing grooves in the rubber rail pads. Rubber pad or grooved rubber rail pad are made up of rubber or plastic to dampen the shocks of vibrations of a passing train.
High Quality Grooved Rubber Rail Pad
Our range of grooved rubber rail pad is very effective to reduce the shocks of vibrations caused by the trains while passing through the tracks. These rail pads are highly demanded in railways due to their robustness, long service life and effective use. With good mechanical features and sustainability, these products can be customized and are available at a reasonable price.

Ray Pad for Crane Rails
The ray pad is an end product made from synthetic elastomer and is used in heavy crane roads and between rail and supporting structure. It is manufactured in various widths determined according to rail base dimensions and standard length of 12m. The rail pad may be manufactured in different lengths and sizes due to special demands.
Installed with resilient crane rail pad, railtrack ia able to keep safe when movement and rotation is at small amounts. Rails lie on a pad (called soft mounting), the stress is distributed between crane wheel and rail, and contact surfaces. GNEE RAIL offers two rail pad types, one for a continuously supported rail and one for discontinuous mounting.
