Rail Anchors Specifications Study in Railway Construction

Rail and Anchor

Rail anchors or anticreepers are used where the fastenings system requires an extra creep resisting arrangement, which are made in one-piece construction from spring steel clips that attach to the underside of the rail baseplate and bear against the sides of the sleepers to prevent longitudinal movement of the rail, either from changes in temperature or through vibration, avoiding undo cutting and wear, thus prolonging the life of rail ties. When driven in the rail, the railway anchor grips the rail firmly.

Rail Anchor Types

• T or V-shaped rail anchors used in 50Kg, 85Kg, 90/91LB, 115RE /136RE, UIC54 and UIC60 rail.
• Rail anchors made of 60Si2MnA and used for rails such as 50kg, 70lb, 80lb, 90/91lb and so on.
• Rail anchors for Russia market: high grade ductile iron castings.
• Customers special reservation

Rail Anchor Function

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. 

Design of Rail Anchor

• To function during their service life without damage to the rail base due to longitudinal forces, application forces, or vibratory action.
• To be able to resist longitudinal and torsional forces exerted by skewed ties without damage to the base of rail.
• To be capable of being applied tightly against the tie either manually or by machine.
• For easy application, removal and successive reapplication without appreciable loss of holding power as required by the following slip test.

Rail Anchor Bearing Area

Rail anchors shall have sufficient bearing area and depth to minimize the possibility of the anchor damaging or becoming embedded in the tie under pressure and to prevent the anchor from overriding the tie.
