 at least one fastening stud capable of being fixed to the track formation;   at least one cradle capable of supporting the track panel; and   means for vertical movement of said cradle relative to said stud so that a height of the panel relative to said track formation can be adjusted and the superelevation of the track section can be defined;   wherein the cradle is mounted so as to be movable vertically in said stud along a vertical axis perpendicular to the longitudinal axis.   
     
     
         2 . The support according to  claim 1 , wherein the fastening stud comprises at least one lateral wall connected to a base and extending along the vertical axis, said lateral wall being configured to guide said cradle along the vertical axis. 
     
     
         3 . The support according to  claim 1 , wherein said means for vertical movement of a cradle comprises:
 a wedge mounted so as to be movable substantially along a transverse axis relative to said stud and that carries said cradle;   means for horizontal locking, along the transverse axis, of said cradle relative to said stud, so that a horizontal movement of said wedge causes a vertical movement of said cradle, said wedge and the cradle having complementary means configured so as to guide the movement of the wedge relative to the cradle; and,   means for horizontal movement of said wedge in said stud along the transverse axis.   
     
     
         4 . The support according to  claim 3 , wherein said means for horizontal locking of said cradle relative to the stud comprises a threaded insert in engagement in said stud and extending horizontally through the stud bearing against said cradle. 
     
     
         5 . The support according to  claim 3 , wherein said means for horizontal movement of said wedge comprises an adjustment screw bearing against said wedge and in engagement in said stud while extending horizontally through said stud. 
     
     
         6 . The support according to  claim 2 , wherein the base of the stud comprises at least one first upper inclined plane on which said wedge is mounted, the first upper inclined plane being complementary to a lower inclined plane of the wedge. 
     
     
         7 . The support according to  claim 1 , wherein the cradle comprises at least two lower inclined planes that are complementary to two upper inclined planes of the wedge, the two lower inclined planes being oriented in substantially opposite directions. 
     
     
         8 . A guided transport track section intended to be fixed to a ballastless track formation, the track section comprising a track panel having:
 two stringers extending along a longitudinal axis, each stringer also comprising an upper longitudinal groove for receiving a rolling and/or guiding element for a guided transport vehicle, such as a rail; and   at least one structure that is rigidly connected to said stringers and extends transversely between them;   wherein the track section comprises a plurality of supports for the panel comprising at least one fastening stud capable of being fixed to the track formation, at least one cradle capable of supporting the track panel, and means for vertical movement of said cradle relative to said stud so that a height of the panel relative to said track formation can be adjusted and the superelevation of the track section can be defined, wherein the cradle is mounted so as to be movable vertically in said stud along a vertical axis perpendicular to the longitudinal axis, and, suitable for being fixed to said track formation and configured to be capable of supporting said panel above said track formation so that the height of the panel relative to said track formation can be adjusted and the superelevation of the track section thus formed can be defined by means of coordinated adjustment of the various cradles.   
     
     
         9 . The guided transport track section according to  claim 8 , wherein the structure comprises at least two sleepers or a slab rigidly connected to the stringers. 
     
     
         10 . The guided transport track section according to  claim 9 , wherein the slab comprises a central rib arranged between the two stringers. 
     
     
         11 . The guided transport track section according to  claim 8 , wherein each stringer has a rounded lower face of a the same shape as the upper faces of said cradles of said supports. 
     
     
         12 . The guided transport track section according to  claim 8 , wherein the section comprises at least two supports per panel. 
     
     
         13 . The guided transport track section according to  claim 8 , wherein said stringers and said supports are made of concrete. 
     
     
         14 . The guided transport track section according to  claim 8 , wherein said fastening stud is mounted on a metal block comprising a metal plate and a plurality of placement elements welded beneath the metal plate and extending along an axis perpendicular to the plate, said metal block being intended to be inserted in said track formation by driving or sinking in order to fix a corresponding one of the supports. 
     
     
         15 . A ballastless track for a guided transport vehicle comprising a track formation and a plurality of track sections fixed successively to said track formation each of the track sections comprising a track panel having:
 two stringers extending along a longitudinal axis, each stringer also comprising an upper longitudinal groove for receiving a rolling and/or guiding element for a guided transport vehicle, such as a rail; and   at least one structure that is rigidly connected to said stringers and extends transversely between them;   wherein the track section comprises a plurality of supports for the panel comprising at least one fastening stud capable of being fixed to the track formation, at least one cradle capable of supporting the track panel, and means for vertical movement of said cradle relative to said stud so that a height of the panel relative to said track formation can be adjusted and the superelevation of the track section can be defined, wherein the cradle is mounted so as to be movable vertically in said stud along a vertical axis perpendicular to the longitudinal axis, and, suitable for being fixed to said track formation and configured to be capable of supporting said panel above said track formation so that the height of the panel relative to said track formation can be adjusted and the superelevation of the track section thus formed can be defined by means of coordinated adjustment of the various cradles.
