Claim:
A platform screen door system ( 11 ) for railway stations, comprising: a plurality of sliding doors ( 15 ), said sliding doors being arranged on substantially parallel planes and being capable of overlapping at least partly when sliding relative to each other in order to define corresponding access passageways, wherein adjacent ones of said sliding doors define respective access gates and wherein said adjacent said sliding doors ( 15 ) have a first, closed configuration, in which said gates are closed by the sliding doors ( 15 ) and access to a track where trains run is prevented, and a second, open configuration in which one of said access passageways (P) for allowing access to a train is defined in at least one of said gates, wherein said adjacent sliding doors lay mutually staggered on corresponding parallel non coinciding first and second planes in both of said closed and open configurations and while sliding from said closed to said open configuration, said sliding doors comprising a locking device in order to lock the doors in said closed configuration each of said sliding doors being provided with an independent motorised driving assembly thereby permitting to compensate for stopping errors of a train, by controlling the opening strokes of each of said doors in the platform screen door system depending on the positions of train doors, further comprising a set of uprights ( 13 ) defining said gates therebetween, respectively; a horizontal beam ( 17 ) extending between a top of said uprights ( 13 ); wherein said sliding doors ( 15 ) arc arranged between said uprights ( 13 ) so as to close said gates, said sliding doors being arranged to horizontally slide relative to said uprights so as to define said corresponding passageways (P) in said gates, wherein the uprights ( 13 ) are formed by a pair of rectilinear members ( 13 a , 13 b ) vertically arranged parallel to and spaced apart from each other so as to define a gap ( 13 c ) through which said sliding doors ( 15 ) pass.
