If you are going to Tutuban from Alabang or vise versa, you may ride the 8100 Series of Diesel Multiple Unit (DMU) trains for free.
The Philippine National Railways (PNR) has began deploying its newly acquired Inka trains on February 18, 2020, opening its Tutuban-Alabang route.
According to PNR General Manager Junn Magno, the trains will have to go through a 150-hour validation and static test before being deployed for commercial use. But the PNR will open the trains to the public free of charge during their first 450 hours.
Meanwhile, we can expect the arrival of the Diesel Hydraulic trains that can run through floods in April.
