In the region of the track (2) the roadway is formed by inner (3) and outer (A) roadway plates whereby the inner plates (3) are self-supporting and bridge the distance between the rails (5) of the tra ck (2) and have at their edges bordering the track pro- jecting bearing ribs (7) by which the inner plates (3) are supported on the rail bases (10), laterally against the rail web (11) and at the top against the rail heads (12) with the insertion of elastic, shaped supports (8, 9) of rubber or plastic whereby lower support- ing components (8) with an angular cross-section are provided to locate the bearing ribs (7) of the inner plates (7) on the rails (2) which bear on the rail base via one shank (18) while the other shank (20) is beside the rail web (11). The top (28) of the shank (18) of the angular cross-section lower support (8) lying on the rail base (10) a nd the base (23) of the bearing ribs (7) supported there- on run approximately parallel to the top (29) of the rail base. A plurality of adjacent grooves (31) is provided at least on the bot- tom (30) of the shank (18) of the lower support (8) lying on the rail base (10) and preferably also on the other surfaces facing the rails (2).
