Drive-on (knock-on) rail anchors and Spring type (wrench-on) rail anchor
Rail anchors made in one-piece construction from spring steel are designed to fasten the rail tight on the base of the rail to prevent the rail from longitudinal movements, i.e. the “ creeping” of the rail, caused by changing temperature, grades, traffic patterns, and braking action of trains.
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 rail tie, preventing cutting and wear, and eventually to prolong the working life of the rail 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
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.
Locations of Rail Anchors:
Usually, rail anchors are used in the following locations of rail ways.
When anchors are used, taking a 39 foot rail for example, 8 rail anchors is usually commended to be used, as shown in the following diagram. While the steep grades increased, the number of the anchors may be increased.

Recommended Minimun Anchoring Pattern for 39-foot Rails.
At open beck bridges. Anchors are used on track approaching open deck bridges, every third tie should be box-anchored for at least two rail lengths off each end of the bridge.
At rail crossings. As rail crossings where anchors are used, every third tie should be box anchored for at least two rail lengths in all directions from the crossing.
Rail turnouts. Anchors is optional used in turnouts. When anchors are used in the turnouts, it is helpful to correct the geometry problems.
Types of rail anchors:
1. Rail anchors are always used in rails such as 50kg, 85kg, UIC54, UIC60, 90/91lb, 115RE, 136RE, just to name a few. We can produce T or V-shaped rail anchors as well as other types according to clients’ requirements, by forging or casting.
