Design and installation of dual gauge switches
			Three rails track junctions: improving the prototypes		
				Development of the work
The implementation plan of the Mediterranean Corridor in international gauge has meant an enormous technological challenge to implement the Iberian and international gauges in the same track, from the compatibility of the route to the railway signalling, to allow a safe operation and a reliable operational functionality. It implies an important increase in complexity, with the appearance of pathologies in the operational phase, due to the scarce experience accumulated in its use, which requires continuous viable, solvent and reliable improvements.
