Abstract: 1. Guideway supports, in particular for a magnetic levitation train (100), to form a guideway by several supports (2) following each other in the direction of travel, with a first upper support segment (12), in particular an upper flange (12), and at least one supporting segment below the upper support segment (12), in particular a ridge (13,14), whereby the support (2) has a cross-section of hollow configuration, whereby the hollow space (16) is delimited on top by the upper support segment (12), laterally by a ridge (13, 14) on either side, and below by a second support segment (15), characterized in that the surfaces and masses of the support (2) irradiated by the sun are similar on the first support segment (12) and the second support segment (15), in that the heating of the support (2) in the area of the first support segment (12) and in the area of the second support segment (15) is even in order to achieve a low temperature gradient and an even temperature expansion, and in that means are provided on the support to assist in the even temperature expansion. 2. Guideway as in claim 1, characterized in that the means are solar cells (7, 8) and/or solar collectors installed in the area of the area of the upper support segment (12) and/or of the (at least one) support segment (13, 14). 3. Guideway as in claim 1 or 2, characterized by the erection on one or several pillars (5) imbedded in the soil. 4. Guideway as in one of the preceding claims, characterized in that the faces of the support segments (13, 14) across from each other of two supports (2) following each other in travel direction essentially connect to each other. 5. Guideway as in one of the preceding claims, characterized in that the solar cells (7, 8) and/or the solar collectors are installed on at least one of the surfaces pointing to the outside of the (at least one) support segment (13, 14) and/or of the upper support segment (12). 6. Guideway as in one of the preceding claims, characterized in that several fields of solar cells (7, 8) and/or solar collectors are placed adjoining each other in the sense of the guideway. 7. Guideway as in one of the preceding claims, characterized in that means installed on the support are a heat absorbing and/or reflecting surface on the outside of the support (2). 8. Guideway as in the preceding claim, characterized in that the heat absorbing and/or reflecting surface is a coat of paint on at least part of the outside of the support (2). 9. Guideway as in one of the preceding claims, characterized in that the means installed on the support are shading elements assigned to at least parts of the outside of the support (2). 10. Guideway as in one of the preceding claims, characterized in that the means provided on the support are means for heat interchange, in particular for heat exchange, installed between the first flange (12) and the second flange (15). 11. Guideway as in one of the preceding claims, characterized in that the means for heat interchange are channels (21) with heat-conveying liquid, in particular oil. 12. Guideway as in one of the preceding claims, characterized in that the means for heat interchange are cooling and/or heating elements. 13. Guideway as in one of the preceding claims, characterized in that a prestressing steel (19) without adhesion to the concrete is provided in the outer areas of the flanges (12, 15). 14. Guideway as in one of the preceding claims, characterized in that centered prestressing steel elements (19) are installed between the support segments (13, 14). 15. Guideway as in one of the preceding claims, characterized in that the centered prestressing elements are thermally insulated. 16. Guideway as in one of the preceding claims, characterized in that the means installed on the support are presses controlled in function of temperature by means of which the support (2) can be deformed in particular through unilateral heating of the relevant prestressing elements (19). 17. Guideway as in one of the preceding claims, characterized in that the presses are connected to corresponding solar cells and/or solar collectors.
