ABSTRACT:
A steel tie for incorporation in rail track has a horizontal rectangular plate for connection transversely of the rail to restrain vertical rail movement. The longer sides of the horizontal plate terminate in downwardly and outwardly inclined margin portions for capturing ballast. A web member extends vertically on the underside of the plate member and parallel to and centrally of the longer sides of the plate and serves to restrain longitudinal rail movement. Curved ballast engaging plate members are connected on the underside of the tie to provide lateral stability. The plate members are detachable and replaceable with smaller or larger members to provide a smaller or greater ballast engaging area. The lower edge of the vertical web has a thickened portion to carry stresses. Rail fastening devices consist of a pair of opposing longitudinally extending shoulders adapted to accommodate the rail flange between them. Each shoulder has a downwardly facing abutment surface, and a resilient rail clip has an intermediate portion that bears upwardly on the abutment surface, an end portion that extends inwardly from the abutment surface and bears resiliently on the upper side of the rail flange.
