[origin: EP1045069A2] The ballastless superstructure is for a railway track and employs prefabricated concrete plates (1a), which in thee superstructure longitudinal direction have a greater extent than that crossways. The plates have at least two, particularly symmetrically arranged recesses extending from top to bottom, which are particularly rectangular and are downwardly open. Differ length sides are provided, the longer sides extending in the longitudinal direction of the superstructure. At least two adjacent concrete support plates (1a) at least on their face sides beneath the rail foot have different thicknesses and the mortar (6,6a) beneath the support plate with the lesser thickness is at least formed in two layers. The upper layer exte to the area of the seam and a lower layer directly next to the ground extends beneath the support plates of different thicknesse
