Abstract: A rail support block assembly includes a resilient member and a molded block having a top, a bottom and peripheral wall. The block is adapted for fastening one or more rails on the top. The prefabricated resilient member has an outer tray and inner tray arranged within the outer tray, and includes a resilient intermediate structure between the trays. The block is molded. The block is fixed in the inner tray to extend under the bottom of the block and along a lower region of the peripheral wall. The resilient member may form a part of the block mold, so that a mold member combined with the resilient member delimit the mold for the block. The moldable material is introduced and adheres directly to the inner tray of the prefabricated resilient member.
Abstract: A miter rail system for spanning a railroad track joint includes a fixed rail and a lift rail formed from thick web rail stock. The joining ends of the fixed and lift rails are notched to interfit with each other along a predetermined longitudinal extent along the notches so that at least gage sides of the associated fixed and lift rails are in alignment with each other to provide a generally smooth and uninterrupted surface for rolling stock wheels. Preferentially, the inward facing edge of the notch is substantially entirely coextensive with a side of the thick web as a result of milling out, once the ends of the rails adapted to face each other have been bent.
Abstract: A support device which can be applied to rails (R) of railway or tram tracks includes a bracket (1) having two attachment parts (6) for attachment to the rail (R) on opposite sides of a sleeper (T), a resting part (4) which rests on the sleeper (T), and is set at a distance from the attachment parts (6), and clamp members (7) for connection of the attachment parts (6) to the flange (S) of the rail (R). The bracket is arranged for supporting a service device such as a transit platform, sound barriers or other devices.
Abstract: A modular rail system for positioning a six axis robot about an auxiliary axis includes a plurality of rail sections which are selectively interconnected in order to provide a reconfigurable length about the auxiliary axis, and the six axis robot for movement with respect to the rail sections about the auxiliary axis. The rail sections may include a first end section positioned toward a first end of the auxiliary axis, a second end section positioned toward a second end of the auxiliary axis, and one or more intermediate sections positioned between the first and second end sections. The first end section, the intermediate sections and the second end section are interconnected along the auxiliary axis.
Abstract: A support system for a rail section which bridges the gap between foundations which are relatively movable auxiliary rails running parallel to the rail across the sleepers which are supported by the foundation, and underpinning supports providing a stiff connection between rail and auxiliary rails. The underpinning supports move in response to relative movement of the foundation so that undesirable rail bending is avoided.

Abstract: A double-gauge rail system for the rolling stock of railroad trains including pairs of rails of differing gauges, with the rail track sections of each gauge being in axial alignment but separate and not welded together at the section ends. The inner and outer rail sections of the two gauges at least partially overlap so that the inner rail sections extend across the gaps of the outer rail sections and, likewise, the outer rail sections extend across the gaps of the inner rail sections. To provide continuous contact between the wheels and rails sections, each axle of a vehicle car or engine has pairs of wheels on each end of the axle; the outer pair of wheels corresponding to the outer gauge and the inner pair of wheels corresponding to the inner gauge, so that the wheels of at least one rail gauge are in contact with the corresponding pair of rail sections.
Abstract: The railway crossover includes two main tracks and a third track running between the main tracks and having an axis inclined to respective parallel axes of the main tracks, a plurality of ties each having a relatively long tie and a relatively short tie forming a respective pair of ties and having respective inner ends neighboring one another, inner ends of long ties of subsequent pairs of ties are arrayed alternately on both sides of an axis of the third track at least three subsequent long ties being connected rigidly to one another by connecting joint bars.
Abstract: A system for the laying of panel track that includes a plurality of panel tracks, a railroad car containing the panel tracks, and a panel track lifter positioned in the railroad car for lifting the panel tracks from the railroad car and for placing the panel tracks exterior of the railroad car. Each of the panel tracks includes a first rail, a second rail, a plurality of ties extending between and beneath each of the rails, and a plurality of gage rods affixed at various locations along the rails. A tension bar extends angularly between the first and second rails so as to create a curvature in the rails. The railroad car includes a material container having a generally flat floor extending between a pair of side walls. The material container has trucks suitable for rolling along a panel track. The material container is made up of a plurality of railroad cars having a flat floor extending throughout the plurality of railroad cars.
