Claims
- 1. 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.
- 2. A method according to claim 1, comprising the further step of using an adhesively bonding material with a degree of resiliency to seal between the rail and the recess.
- 3. A method according to claim 1, comprising the further step of forming a second elongate rail with a recess in said roadway at the same time as the first mentioned elongate rail so that the rails and recesses are accurately located relative to each other.
- 4. A method according to claim 1, comprising the further step of welding the rail from lengths of rail track which have been pretensioned.
- 5. A method according to claim 1, wherein the bar portion is approximately 7 centimeters deep with 4 centimeters recessed into the roadway and said clearance is up to a 0.25 centimeter clearance between a bottom of the rail and a bottom of the recess, the bar portion being approximately 10 centimeters wide with the flanges each extending a further 4 centimeters.
- 6. A method according to claim 1, including the further steps of forming a further rail intersection, and forming grooves in the intersecting rails, the intersecting rails crossing at an angle with said grooves in the rails extending across the intersection.
- 7. 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 central 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 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.
- 8. A method according to claim 7, wherein the beam is wider than the rail inclusive of said flanges.
- 9. A method according to claim 7, including the further step of forming the concrete beam with recessed regions to each side of said recess, said flanges being supported on said recessed regions.
