Anchor Rail Fastening System

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.

Description

Technical Parameters

↵Rail Anchor Fastening System

A Railway Anchor is a specially shaped steel device designed to be driven onto the base (foot) of a rail to prevent longitudinal movement, known as rail creep. It does not fasten the rail to the sleeper but instead grips the rail foot and bears against the sleeper's shoulder, transferring longitudinal forces from the rail into the sleeper and ballast bed. It is a critical component for maintaining track stability and alignment, especially on gradients, curves, and at braking/acceleration zones.

Functional & Engineering Perspective

Anti-Creep Function: Its primary role is to resist and counteract longitudinal rail movement caused by thermal expansion/contraction and tractive/braking forces from trains.

Frictional & Bearing Mechanism: Provides restraint through a combination of friction (tight grip on the rail foot) and direct bearing (contact between the anchor body and the sleeper face or shoulder).

Non-Fastening Role: Crucially distinct from fasteners like clips or spikes; an anchor works in parallel with the fastening system, which retains the rail vertically and laterally.

Maintenance & Operational Perspective

Strategic Installation: Applied at calculated intervals (e.g., every 2nd, 4th, or 8th sleeper) rather than on every sleeper. The pattern is based on expected longitudinal force levels.
Location-Specific Necessity: Deployed with higher density on steep grades, sharp curves, at rail joints (if present), near bridges/culverts, and in braking/acceleration zones.
Sleeper Type Compatibility: Designs vary for concrete sleepers (bearing against a molded shoulder), wooden sleepers (bearing against a tie plate or the tie itself), and steel sleepers.
