Purchase

As part of the Philippine National Railways' modernization program, PNR received a budget through the 2018 General Appropriations Act for the purchase of trains.[6] On May 28, 2018, four sets of four-car trains were ordered together with three INKA CC300 locomotives and fifteen passenger coaches worth ₱2.5 billion (US$47.4 million).[7][8][9]

Design and features
The interior of the 8100 class trainset in February 2020.

The trains were manufactured by the Indonesian firm PT Industri Kereta Api (Persero), also known as INKA. The design of the 8100 class is identical to the 8000 class DMUs deployed earlier with three double-leaf sliding doors per side and longitudinal seats, with the exception of additional intermediate coaches; the 8100 classes comprises 4 units unlike the earlier 8000 units with just 3. The 8000 and 8100 class DMUs as well as the 8300 class coaches are given the designation K3 while in Indonesia.

The DMU train sets has an obstacle door detector that keeps passengers from being caught in between doors with Emergency door release that opens the door manually in case of emergency.[2]

The trains are equipped with polycarbonate glass windows that can withstand damages from stoning, four roof-mounted air-conditioning units (each train car has one unit) suitable for the local tropical climate, and an emergency intercom equipped with two way communication.[2]

The trains also feature an LED passenger information system display in each train car.

Operations

The trains were delivered in two batches: the first batch of trains arrived in February 2020, while the second batch arrived in March 2020. The first batch of the 8100 class DMUs were unveiled on February 14, 2020 and inaugurated on February 20, 2020 at the Tutuban station.[2] These underwent 150-hour RAMS validation before it entered revenue service.[4] The tests for the trains have continued and were successful amidst the effects of the COVID-19 pandemic. Meanwhile, on March 28, 2020, the second batch of two train sets consisting 8 vehicles have been shipped and arrived in the country.[10] The two train sets also underwent RAMS validation tests from May 21 to 31, 2020 before it entered revenue service.[11] It entered revenue service when PNR resumed operations on June 1, 2020 upon the lifting of the metropolis' Modified Enhanced Community Quarantine.[12]

The four train sets entered revenue service in June 2020.[2]

From February 2020 to March 2020, the trains serviced the Metro South Commuter line from Tutuban to FTI stations and vice versa, and since June 2020 the trains now service until Alabang stations and vice versa.
