The rail anchors are used where the fastenings system requires an extra creep resisting arrangement. There are various shapes of the anchor which is made of rolled bars of various sections. When wheel runs on the rail, the railway anchor grips the rail firmly and when set against sleepers, resists longitudinal movement of the rails caused by passing trains.

For heavy rail tracks such as 50kg, 70lb, 80lb, 90/91lb, best option for steel material is 60Si2MnA, based on our former production experience and customer feed back, this material shows more stable mechanical property than most common material for rail anchor production is 60Si2MnA.
The track anchor is mounted directly on the track base and rests against the sleepers. It is used to fix the track to the base plate and sleepers. It adopts an integrated structural design to prevent longitudinal movement of the track, that is, track "creep" caused by temperature changes, slope, traffic patterns and train braking action. It provides a large bearing surface for the track base and sleepers, preventing cutting and wear, thereby extending the service life of the sleepers. Track anchors are manufactured according to specific track weights and base widths and can be divided into two types: driven track anchors and spring-loaded track anchors.
The rail anchors should be located on the gauge side of the rail base, against the same sleeper face on the opposite track.
The rail anchors must be tightly fixed to the rail base and fully supported on the sleeper face.
When the support of the rail anchor on the sleeper is disturbed, a new rail anchor and sleeper will be required.
The anchors must not be moved by driving along the track.
The sleepers should be kept straight when the anchors are used.
