         23 . Group according to  claim 22 , wherein said at least two grooves are rectilinear. 
     
     
         24 . Group according to  claim 22 , wherein at least one of said at least two grooves is blind, in the sense that at least one of the ends of the groove does not open onto an end of said block. 
     
     
         25 . Group according to  claim 22 , wherein said grooves of a block are all parallel and spaced at a same spacing, preferably between 450 and 750 mm. 
     
     
         26 . Group according to  claim 22 , wherein at least one of the assemblies comprises a railway turnout, bifurcation, crossing, dilatation device or the like, wherein said support is a turnout support and said turnout comprises said rail. 
     
     
         27 . Group according to  claim 26 , in which at least one block comprises a recess configured to allow the installation of at least part of a maneuvering mechanism, such as a motorization, a locking system, a wedging system, a referral system, a rodding system, or a heating system. 
     
     
         28 . Group according to  claim 26 , in which said turnout comprises a switch zone, and said two identical blocks are configured to support at least part of said switch zone. 
     
     
         29 . Group according to  claim 26 , wherein said turnout comprises a frog, and said blocks are configured to support said frog. 
     
     
         30 . Group according to  claim 26 , in which said fastening devices comprise a baseplate. 
     
     
         31 . Group according to  claim 30 , wherein said baseplate is provided with two holes each having a long length, the holes being arranged on either side of said rail, said long length being in the longitudinal direction of said rail, and of sufficient length to allow intersection of the vertical projection of each of said holes with a same groove, on the upper face of a block. 
     
     
         32 . Group according to  claim 26 , wherein said turnout comprises a frog, said assembly comprising a frog support disposed between said frog and at least one block. 
     
     
         33 . Group according to  claim 26 , wherein said turnout comprises a direct track and the grooves are perpendicular to said direct track. 
     
     
         34 . Group according to  claim 26 , wherein said turnout comprises a switch zone, and at least one block located at the switch zone has a larger dimension in the direction of travel than its dimension in the direction perpendicular to the travel. 
     
     
         35 . Group according to  claim 26 , wherein said track unit comprises a crossing zone and at least one block of the crossing zone has a smaller dimension in the traffic direction than its dimension in the direction perpendicular to the traffic. 
     
     
         36 . Group according to  claim 22 , in which the two assemblies each comprise a plain track section. 
     
     
         37 . Group according to  claim 26 , wherein the two assemblies each comprise a railway turnout, bifurcation, crossing, dilatation device or the like, wherein said support is a turnout support and said turnout comprises said rail. 
     
     
         38 . Group according to  claim 37 , wherein each track unit comprises at least one switch rail and a maneuvering mechanism comprising at least one means of applying a maneuvering force to a point of application of said switch rail in order to move it between an open position and a closed position, wherein the distance between the point of application closest to the free end of said switch rail and at least one edge of the block above which said point of application is disposed, is the same for both sets, the turnouts of the first and second sets having different geometries.
