Rail anchors or called rail anticreepers are spring steel clips that attach to the underside of rail tie plates and bear against the sides of rail sleepers. The function of rail anchors is to prevent longitudinal movement of the steel rails, either from changes in temperature or through vibration. Rail anchors are applied to the rail base directly and lodge up against the rail ties. Rail anchors can provide a large bearing surface against rail base and rail ties, preventing cutting and wearing, and eventually to prolong the service life of the rail ties. Rail 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 anchors.

How to use the rail anchors?
There are general rules on the application 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.
Rail anchors have been an essential component of railway tracks for many years, providing stability and safety to the tracks. However, with recent technological advancements, rail anchors have become even more effective and efficient at their job.
One of the recent technological advancements in rail anchor production is the use of computer-aided design (CAD) and computer numerical control (CNC) machines. These technologies allow for more precise and accurate production of rail anchors, resulting in better quality and consistency of the final product.
Another recent advancement is the use of high-strength materials such as composite materials or high-strength steel in the production of rail anchors. These materials offer increased durability and longevity compared to traditional materials like cast iron or steel.
