Abstract: The invention relates to a ballastless track section for a rail vehicle, said section being fastened to a platform (10) and comprising: a prefabricated concrete track slab (20, 120) comprising two stringers (21, 22); a rounded bearing surface (21c, 22c) borne by an underside of each stringer at each longitudinal end and having a curvature, the center of curvature of which is the top of a rail (21b, 22b) borne by the stringer; a prefabricated support pad (30, 130) for supporting each longitudinal end of the slab (20, 120) and comprising at least two support bases (33, 34) for the two stringers of this longitudinal end of the slab, each base (33, 34) comprising at least one shim (33a, 34a) of predetermined thickness supporting said rounded bearing surface (21c, 22c) of the stringer of said slab facing this base.

Abstract: The invention relates in particular to a guided transport track section intended to be fixed to a ballastless track formation (15), characterised in that said section comprises: a track panel (20) comprising two stringers (21, 22) and at least one structure transverse to the stringers (23, 24), each stringer (21, 22) comprising an upper longitudinal groove (25) for receiving a rail; a plurality of panel supports (31, 32, 33, 34), each support comprising at least one stud (35) for fastening to the track formation, a cradle (37) for supporting a stringer (22) that is mounted so as to be movable vertically in said stud (35), and means for vertical movement of said cradle (37) relative to said stud (35) so that the height of the panel (20) relative to said track formation (15) can be adjusted, and the superelevation of the track section thus formed can be defined by means of coordinated adjustment of the various cradles (37).
