What is rail anchor

Oct 29, 2025 Leave a message

Rail anchors,also called anticreepers, like Tr37, Tr45 and Tr57 anchors, are used in the fastenings system for creep resistance function.They are made of spring steel with elasticity that attach to the underside of the rail base plate and bear against the sides of the sleepers to prevent longitudinal movement of the rail, either from changes in temperature or through vibration, prolonging the life of rail ties.Rail anchors grisps the steel rail during the train running through the steel rail.

 

rail fastening

 

Rail anchors transmit static and dynamic longitudinal forces in the rail to the cross tie. A sufficient number of anchors are required to hold the rail in a fixed position.

 

The raw material of the rail anchors are 60Si2MnA, 45# Carbon Steel, QT500-7 cast iron, etc.

 

The costings:Shot Blasting, Black, HDG, or as per requirement.

 

Application Rules of 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.
