Abstract: The invention relates to a rail support point for a rail-guided vehicle for anchoring in a wooden tie, including a plate as a support for the rail, which plate is anchored on both sides of the rail by means of fastening bolts that pass through the plate, the plate having on its bottom side collars that surround the fastening bolts and that engage in correspondingly shaped depressions in the wooden tie, the plate being configured as a ribbed plate having raised ribs that are arranged lateral to the rail foot and that guide the latter and being made of plastic, and the collar being embodied as a slitted ring. Also disclosed is a rail fastening using the rail support.
Abstract: A support plate, particularly a ribbed plate for fastening rails of railroad tracks and track switches on wooden sleepers. The support plate is connected in the vicinity of its ends, in each instance, with the wooden sleeper by means of screws or the like which engage in the through-holes, whereas the rail flange is supported in each instance in the area of the plate between the fastening points on the sleeper side. On the underside of the plate, shoulders are provided or constructed only in the area of the through-holes for the fastening screws, which shoulders project out of the plane of the plate and have a thickness of approximately 1 mm to 2 mm. As a result of the cooperation between the shoulders and the fastening screws, the support plate has a convex curvature, so that its underside comes in supporting contact with the upper surface of the wooden sleeper.

Abstract: A rail fastener is described comprising a rail plate, a rail seat defined in an upper surface of the rail, rigid rail clips for engaging the flanges of the rail, bolts for securing the rail clips to the plate, a resilient pad mounted underneath the rail seat and extending the full width of the rail plate, and apparatus for securing the plate and pad against lateral movement with respect to the support structure while permitting the plate to move vertically. The plate securing apparatus preferably comprises a plurality of holes in the rail plate and pad, a tube within each hole, and a support plate on which the tube rests. Each tube has a hollow center and each support plate has a hole aligned therewith. A fastening element is driven through each tube and hole to secure the tube to the underlying support structure without contacting the rail plate.
