E-clip Rail Fastening System,
Rail Anchors  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.
