THE almost daily glitches that disrupt the operations of the EDSA-MRT have impacted 500,000 to 600,000 commuters daily. With lesser number of trains, the number of riders appears to have gone down to about half. There is no peak or non-peak period to speak of since the MRT operates at almost maximum level throughout its operating hours—commuters waiting for trains quickly fill up the station platforms in both directions and fill up the trains even faster upon arrival.
