ABSTRACT OF THE DISCLOSURE A rail fastener comprising a U-shaped clip having a rectangular locating aperture in at least on of its legs which engages over a rectangular retraining block. The retaining block has a retaining pin extending through it to project from each side and bear downwardly on the upper leg of the clip and thereby apply a downward pressure at each end of the lower leg. One end of the lower leg ? downwardly on the rail support and the other end on the rail to impart a total pressure. The reduced cross-sectional area of the clip where it passes over the retaining block causes high stresses in the legs of the clip as well as at ? locality of the clip heel, and this results in a lower sering rate for the toe clip so that toe pressure is ? lo up ? rail settlement. - 1 -
