The MRT 3 or the Metro Rail Transit will be in a 24/7 schedule starting June 1, 2009 to experiment on making this as permanent operating hours. It's a welcome development for the riding public and it was considered for implementation mainly because of the growing demand for MRT 3 operations from BPO night shift workers.My only concern about this is the night time security outside of the premises of MRT 3 stations as most of the stations are not immediately adjacent to BPO hubs like in Ortigas and Makati. You may need to walk a few blocks more or ride an FX to be reach these offices. I particularly have a friend that always have to take the overpass...
