Railway elastic pad from GNEE RAIL
The rail pad, also known as bottom plate, is an elastic polyurethane pad assembled between the rails and sleeper to protect the top of the sleeper from wear and impact. The initial stiffness of the rail pad is not so high that the deformation of the rails under the load of the spring is very large. This mechanism ensures that the rail pad moves as close as possible to realize close contact with the track.
GNEE RAIL provides exceptional elastic rail pads of various types for high-speed railways, normal-speed railways, and cranes. Especially the rail pads made of rubber, EVA, TPEE, and HDPE are very popular with customers. Our railway rubber pads fit the rails such as UIC54, UIC60, BS80lbs, BS100lbs, etc. We have more than 130set of machines in our production lines which can reach an annual production capacity of up to 2000, 000 pieces of rail pads. We offer a wide range of rail pads and other track materials at competitive prices.

Rail pads Functions
Rail pads plays 2 main parts in railway system. It can diminish shock and impact on steel rail, as well as reduce resonant vibration aroused from the concrete sleepers (lowest resonant frequency about 200Hz), and absorb the vibration deviation (about 0.12mm amplitude, 1000Hz) of the track part between sleepers. What's more, rail pads can prevent abrasion and crushing of the sleeper under the foot of the track.
The rubber rail pads are usually designed to have a specific load-deflection characteristic. The initial stiffness of the pads is designed to be very low, making their deformation under the spring toe load quite large. This ensures that despite any vertical movement of the rail, the pad is still in close contact with it. When the wheel is above the pad, the stiffness of the track must be high to prevent large movement, resulting in loose metal spring washers. This load deflection characteristic can be obtained by introducing grooves in the rubber pad.
Packaging of Railroad Pad from GNEE RAIL
- Rubber pads: Typically vacuum-sealed in polyethylene film, then packed in woven bags or wooden crates to prevent moisture and mold.
- Polyurethane pads: Due to higher impact resistance, palletized packaging is suitable. Stack height should not exceed 1.2 meters per pallet, with moisture-proof cardboard between layers to prevent deformation.
- Wooden packaging: Must comply with ISPM 15 standards, including heat treatment and IPPC marking to avoid customs delays.
The advantages of excellent safety performance, reliable high technology, advanced testing equipments of rail pad make itself be widely adopted and manufactured throughout the world together with raw materials with good quality. GNEE RAIL can manufacture various rail rubber pads in different widths according to different railway base dimensions and standard steel rail length to meet customer's special demands.
