Abstract
A track rail having a groove for flanges of rail vehicle track wheels in an upper surface of the rail and having a central bar portion and flanges extending integrally sideways from the top of the bar portion is inserted in a recess preformed in the roadway with clearance so the rail is supported from the roadway's surface by the flanges. The rail is shallow so the recess is only shollowly preformed in the roadway. If the roadway has insufficient load-bearing capacity it is possible to reinforce the roadway by a concrete beam around 30 centimeters wide and 10 centimeters deep grouted with concrete in the road surface; this again is shallow for rail tracks. This beam would be recessed to receive the rail as above and also to receive the flanges.
Claims9
A method of installing rail tracks for rail vehicles, in a roadway for road vehicles, the method comprising the steps of:
- forming an elongate rail with a transverse cross-section comprising a central bar portion and a pair of oppositely directed laterally extending flanges which extend integrally from a top region of the bar portion, the central bar portion having an upper surface which is formed with a groove for receiving flanges of rail vehicle wheels when the wheels are supported on said upper surface;
- forming a recess in the roadway to receive the central bar portion of the rail with a clearance so that the laterally extending flanges rest on a surface of the roadway to each side of the recess and thereby support the rail;
- and
- laying the central bar portion of the rail in the recess with the laterally extending flanges resting on the roadway surface to each side of the recess.

- forming a concrete beam with a recess in which the central bar portion can be located with a clearance;
- laying the beam in the roadway;
- grouting the beam in the roadway with a rigid grout;
- and
- laying the central bar portion of the rail in said recess with the laterally extending flanges resting on the beam to either side of the recess, the rail being thus supported by said laterally projecting flanges.
