Figure 1 shows a side elevation view of an embodiment of an elevated railroad generally indicated by the numeral 10. Figure 2 shows a section view of the elevated railroad of figure 1 at a cutting plane indicated as A-A in figure 1. The elevated railway has two rails 12,14 for rolling stock. In the context of this document, the meaning of rolling stock generally encompasses all vehicles that may move on the railroad, including powered and unpowered vehicles,
locomotives, railroad cars, coaches and wagons. In this but not all embodiments, the two rails 12, 14 have a Vignoles profile. Generally any suitable type of rail may be used, including monorail, flanged T rail, double-headed rail, bullhead rail, and grooved rail. The rails in the embodiment of figure 1 are continuously wielded rails. In another embodiments, however, the lengths of rail may be connected with fishplate or a bar of metal bolted through the web of the rail. The embodiment of figure 1 and 2 has two sets of rails. One of the sets of rails may be used for rolling stock travelling in one direction, and the other of the sets of rails may be used for rolling stock travelling in the other direction. Another embodiment, however, only has one set of rails. Other embodiments may have more than 2 sets of rails. An embodiment having two or more sets of rails may have the same footprint as an embodiment having one set of rails. Consequently, more traffic may use the elevated railroad without necessarily increasing the footprint, which is desirable to in view of environmental and land use considerations.
The elevated railroad 10 has a plurality of towers 16-24 supporting the rails 12,14. In this but not in all embodiments, each tower is supported by a foundation 40, 42, 44, 46, 48 in the form of a foundation block. The foundation block is engaged with the ground. The foundation blocks may be prefabricated concrete foundation blocks made in a factory and subsequently delivered to the tower locations. The ground at each tower location may be prepared for installation thereat of a foundation block. In the case of earthen ground, for example, the earth may be levelled and compacted. The foundation blocks may then be placed on the prepared location. Alternatively, the foundations may be poured at the tower locations. The plurality of towers may be erected on the plurality of foundation blocks. In another embodiment, pile foundations may be used.

In other embodiments, the couplings 26,28 may take any suitable form, for example a socket formed in the elevated railway, a rod that is hook engagable, or steel plates with holes formed therethrough for receiving the ends of the tensioned lateral support members.
To each coupling 26,28 is coupled a tensioned lateral support member 30,32 in the form of a high tensile strength cable such as a high tensile strength steel rope or cable, although any suitable material or composite material of sufficient tensile strength may be used, for example a composite of a fibre and steel, a composite of aluminium and steel, and a length of material having carbon nanotube therein, The steel rope or cable may be spiral steel rope or cable. In alternative embodiments a rod or bar, for example a tensile steel rod, may be used alternatively or additionally to the high tensile steel cable. The profile of the rod or bar may be generally any suitable profile, including but not limited to round, square, channel bar, double tee, and polygon. The tensioned lateral suppo rt member 30,32 may comprise of bundles of high strength wires. At least one end of each of the tensioned lateral support members i
