    摘要： A bonded, direct fixation fastener as supportive structure for a rail on a railroad bed comprising: a substantially rectangular rail plate, wherein the rail plate has a generally horizontal center portion having a lower face and an upper face and wherein the rail plate defines an outer perimeter having a face defining a first angle to the railroad bed, the rail plate having attachment means to attach to the rail; a substantially rectangular bottom member defines an inner perimeter having a face defining a second angle to the railroad bed; and a substantially rectangular elastomeric portion disposed between, and bonded to each of, the outer perimeter and face of the rail plate and the inner perimeter and face of the bottom member.

    摘要： A boltless brace assembly for a rail includes a base block interlocked with a brace, and further includes a wedge to be inserted between an upper surface of the base block and a lower surface of the brace, thereby applying an upward force to the brace and a resultant downward force to secure the rail base. The brace assembly may be modified to provide a universal brace assembly, a resilient brace assembly, or a frog base clamp.

    摘要： A track-mounting assembly secures a longitudinally extending rail direction to a substrate and has a frame fixed to the substrate and a track plate fitted in the frame. A vertically throughgoing aperture of the frame has an inner edge formed by a longitudinally extending gauge surface directed transversely toward a field side of the assembly and a transversely oppositely directed and longitudinally extending field surface. The track plate carries the rail and has an outer edge is itself formed by a longitudinally extending field surface spacedly transversely confronting the gauge surface of the aperture and a longitudinally extending gauge surface spacedly transversely confronting the field surface of the aperture. The field surface of the track plate is of substantially greater area than the gauge surface of the aperture. An elastomeric mass fills between the frame and the track plate.
