The unit (1) has pre-fabricated rail track molded parts (2, 3) arranged parallely at a distance to each other and comprising beam-shaped concrete bodies extending in a longitudinal direction. A spacer is arranged between the concrete bodies, and fixes the concrete bodies in a preset distance to each other. The spacer is formed as a rigid spatial frame (78) or a rolling profile, and is arranged below a concrete filling level. The spatial frame has a reinforcement steel mesh (7) connecting the molded parts. |
