Rail anchors made in one-piece construction from spring steel are designed to fasten the steel 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. GNEE RAIL's Rail anchors provide a large bearing surface against rail base and railroad tie, preventing cutting and wear, and eventually to prolong the working life of the railroad 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.
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. While the steep grades increased, the number of the anchors may be increased.
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.
