(PNA photo) MANILA - The Metro Rail Transit Line 3 (MRT-3) on Monday started the operation of four-car trains as it also kicked off a month-long free ride program following the completion of the line's massive rehabilitation under the Duterte administration. Two four-car trains were so far operational and run simultaneously with the three-car trains in the MRT-3's revenue line. In a statement, MRT-3 Officer-in-Charge General Manager Michael Capati said the four-car trains are scheduled to run during peak hours-beginning at 7 a.m. and 5 p.m. respectively-and are meant to add to the MRT-3's passenger capacity. He noted that each Czech-made CKD train car of the MRT-3 is capable of carrying up to 394 passengers-1,182 passengers per three-car train or 1,576 per four-car train. To date, he said an average of 18 to 22 trains-including four-car trains-are running at the MRT-3's revenue line at any given time. "Malayong-malayo po yung ngayon sa napapatakbo natin noon na 10
