Alstom Axonis of Antipolo Transport Consortium Blue Line Metro:
The Antipolo Transport Consortium (ATC) Blue Line is a rapid transit line that services Antipolo City proper, the suburbs at Bagong Nayon and Marikina City. The line runs mostly on a viaduct though the section from Circumferential Road Station to Antipolo Cathedral Station runs underground and the section from Antipolo Central Terminal Station to Assumption Antipolo Station runs at-grade. The line uses the Axonis turnkey metro system developed by Alstom. The trains, which run in a 4-car configuration, are driverless and use Alstom's Urbalis CBTC signaling system, allowing a minimum headway of 60 seconds. Platform screen doors, in a full height configuration for the underground stations and a half height configuration for elevated and at-grade stations, are used in all of the stations for passenger safety. The line is operated by Corpus Christi Rail (CCRail), the national rail operator of Corpus Christi, which is a member of ATC.
