Railway turn out

Abstract

A railway turnout includes conventional rail components ( 10 ) which are mounted to cross ties ( 12 ) having a top plate ( 20 ). Stirrups ( 22 ) depend downwardly from the top plate ( 20 ). Continuous tubular elements pass through the stirrups ( 22 ) and these elements are pumped with concrete to form continuous longitudinal beams which support the components ( 10 ).

1 . A railway turnout including rail components mounted to cross ties and supported by concrete beams, characterised in that the components are adapted to be supported longitudinally on tubular concrete beams.  
     
     
         2 . The railway turn out according to  claim 1  characterised in that the longitudinal concrete beams are case in situ by forming a continuous tubular element and filling it with concrete to abut the rail components or a structure associated with the components.  
     
     
         3 . The railway turnout according to  claim 2  characterised in that the rails are supported on stirrup formations comprising open bottom channels and the continuous tubular elements pass through the stirrups.  
     
     
         4 . The railway turnout according to  claim 3  characterised in that the stirrups depend downwardly from a transverse plate which serves to support a rail connection.  
     
     
         5 . The railway turnout according to  claim 3  or  claim 4  characterised in that the stirrups are separated by an I beam.  
     
     
         6 . The railway turnout according to any of the above claims characterised in that a series of resilient pads, or a continuous pad is provided beneath the rails.
