Railroad anchors are typically made from one-piece spring steel, with 60Si2MnA being a common and stable grade used for its excellent elastic properties and performance in various weather conditions. Other spring steel grades like 55Si7, 60Si7, 65Si7, 55Si2Mn, 38Si7, and others are also used, depending on the specific requirements of the rail fastening system.

Rail anchors are applied to the rail base directly and lodge up against the tie. Rail anchors provide a large bearing surface against rail base and railroad tie, preventing cutting and wear, and eventually to prolong the working life of the railroad ties. Anchors are made for a specific rail weight and base width, which can be classified into two types: the Drive-on rail anchors and Spring type rail anchor.
Application Rules of Rail Anchors
- Rail anchors should be on the gage side of the rail base against the same tie face on opposite rails.
- Rail anchors have to hold the rail base tightly and firmly and have full bearing against rail tie face.
- A new rail anchor and a rail tie will be needed when the bearing of rail anchor against the tie has been disturbed.
- Anchors shall not be moved by driving them along the rail.
- The rail ties should be kept straightened when the anchors are applied.
GNEE RAIL's rail anchors are manufactured in strict compliance with international standards, with mass production capacity available to clients. GNEE rail anchors ensure full base plate contact, uniformly distribute creep loads, and eliminate sleeper rail biting and rail creeping phenomena.
