Abstract: 1. A rigid track bed of concrete, in particular, of precast concrete components, with a slab (1) and with a continuous or a multiplicity of fastenings (4) for rails (3) to accommodate track guided vehicles, therein characterized, in that on the slab (1), parallel to least one rail (3) on at least one side of a rail (3) a curb (5) is placed as a precast concrete component for the protection of and for guidance during a derailment of the said vehicle, curb (5) is furnished with at least one slot (10) extending transverse to the longitudinal axis of the slab (1). 2. A rigid track bed in accord with claim 1, therein characterized, in that the curb (5) acts as a uniform guide element for a derailed wheel (13'). 3. A rigid track bed in accord with claim 1, therein characterized, in that the plate (1) and/or the curb (5) is a ready made concrete element. 4. A rigid track bed in accord with one of the foregoing claims, therein characterized, in that the rail fastening (4) is installed at support points (2), especially at raised protuberances of the slab (1). 5. A rigid track bed in accord with one of the foregoing claims, therein characterized, in that the curb (5) is integrated in the slab (1). 6. A rigid track bed in accord with one of the foregoing claims, therein characterized, in that the curb (5) is located on that side of the rail (3) which is proximal to the centerline of the tracks. 7. A rigid track bed in accord with one of the foregoing claims, therein characterized, in that the slot (10) is placed proximal to a fissure-blocking position (11) of the slab (1). 8. A rigid track bed in accord with one of the foregoing claims, therein characterized, in that the upper edge (6) of the curb (5) is above the upper edge (7) of the rail (3) by a distance of approximately 20 mm. 9. A rigid track bed in accord with one of the foregoing claims, therein characterized, in that the longitudinal side of the curb (5) proximal to the rail (3) has a separating distance from the top of said rail, which said distance corresponds to an appropriate space to accept a derailed wheel (13') of a vehicle, wherein the said separating distance is about 180 mm. 10. A rigid track bed in accord with one of the foregoing claims, therein characterized, in that the curb (5) is made of high strength concrete. 11. A rigid track bed in accord with one of the foregoing claims, therein characterized, in that in the curb (5) metallic reinforcement is installed. 12. A rigid track bed in accord with one of the foregoing claims, therein characterized, in that the curb (5) is made of fiber reinforced concrete. 13. A rigid track bed in accord with one of the foregoing claims, therein characterized, in that the longitudinal side of the curb (5) proximal to the rail (3) possesses a structural metal member (15), especially an angle iron. 14. A rigid track bed in accord with one of the foregoing claims, therein characterized, in that the structural metal member (15) in the area of the slots (10) is interrupted. 15. A rigid track bed in accord with one of the foregoing claims, therein characterized, in that a structural metal member (15) can be fastened to effect a longitudinal prestress on the curb (5). 16. A rigid track bed in accord with one of the foregoing claims, therein characterized, in that rail fastening (4) is protected from damage by the curb (5).
