The principal role of a railroad anchor is to prevent the railroad track from "creeping", which means the gradual longitudinal displacement resulting from stress imbalance, temperature change, etc. The rail anchors not only clamp on the rails but also against the sleeper so that it can provide sufficient friction and resistance to keep the track from sliding forward when trains pass by. It also helps in eliminating cuts and wear of wooden ties.
Friction Force
Rail anchors are typically manufactured from metallic materials such as steel and feature specialized shape designs. They often adopt wedge or convex structures. GNEE RAIL's rail anchors generate significant friction between the rail and sleeper, effectively preventing rail movement. We offer various rail anchors, including Drive-on rail anchors, Spring type rail anchors, Improved fair anchors, Unit channel anchors, and others.

Elasticity and Compression Force
Rail anchor designs incorporate certain elasticity or compression capabilities. When installed at the rail base, they provide additional compressive force to securely anchor the rail to the sleeper, further increasing friction and reducing the likelihood of rail slippage.
Adaptation to Temperature Changes
During operation, rails expand and contract due to temperature variations (such as thermal expansion and contraction). Our manufactured rail anchors can structurally accommodate these changes, maintaining rail stability and preventing irregular movement caused by temperature differentials.
GNEE RAIL provides rail anchors for a variety of rail sizes to meet a variety of issues and demands. Our rail anchor manufacturing processes assures that our rail anchors will remain the dominant performance in track. Our professional staff provides expertise and timely quotes for whatever is needed, whenever it is needed.
