The system is devised for adapting the bogies of a train to different railway track gauges, including a plurality of bogies made by two half-bogies (1 or 1') which are displaceable by means of lateral sleepers (2 or 2') and a central sleeper (3 or 3'), said displacement being locked by means of locking mechanisms (4 or 4') provided on the lateral sleepers (2') and central sleeper (3'), where the half-axles (5') of the respective half-bogies (1 or 1') are independent. The system further includes a gauge changing platform having lateral displacement bedplates (14 or 14') provided with bogie gauge opening means (9 or 9') and closing means (16 or 16') actuated by means of reversible screws. The system further includes bogie-carrying carriages (10 or 10') which are displaceable along a ditch (13 or 13'), each of said bogie-carrying carriages (10 or 10') being provided with a counterpivot (12) for elevating the transported load during the adaptation maneuvers, such that the gauge opening and closing means do not have to carry out great efforts, and providing also traction to said bogie until the next bogie arrives at the gauge changing platform.
