The PNR Hyundai Rotem DMU is a class of diesel multiple units (DMUs) operated by the Philippine National Railways since 2009.

Purchase[]

During the administration of then-President Gloria Macapagal Arroyo, a project to rehabilitate the PNR Metro Commuter Line was pursued. The first phase of the Northrail-Southrail Linkage Project, includes the purchase of diesel multiple units. 21 DMU cars that can be configured into seven three-car sets were planned to be procured. However, due to budget constraints, the order was downgraded to 18 DMU cars or six three-car sets, as the budget was not enough to cover the seven sets.^[7]

In 2007, the South Korean consortium of Daewoo, Hanjin Heavy Industries and Construction, and Rotem was awarded the contract for the first phase of the Northrail-Southrail Linkage project.^[7] The consortium was appointed by PNR by way of negotiated procurement, wherein the government directly negotiates with contractors in case of an emergency. This happened after two failed biddings in early 2007.^[7]

The US$49.096-million project was funded by a US$50.42-million loan from the Export–Import Bank of Korea.^[7]

Design[]

Car body[]

The train was introduced as the first lightweight, stainless steel made trainsets of the PNR in 2009.^[4] The trains have 2 double-leaf, electro-pneumatically operated sliding doors per side.^[3]

When the trains first entered service, there were two livery variants. There were DMUs that sported a silver-colored body and orange lining with white-colored front cabs and the old PNR logo used in the 1960s. Another was a variant with the same silver-colored body and orange lining but with the cabs sporting colors of white and blue, and stylized PNR FilTrack logos on the side windows of the front cabs and in the middle of the ITR car.

By 2015, all remaining active DMU units sported a navy blue livery, while still maintaining the orange lining in its sides.

The current livery used since 2019 has orange at the front and the body is mostly covered white with blue stripes at the side. The PNR logo is placed at the front of the Rotem DMUs.

Interior[]

The seats of the trains are longitudinal-type and are made up of fibre-reinforced plastic.^[5]

Bogies and electrical components[]

The front and rear bogies of the DMR cars are engine-propelled driven, while the bogies under the ITR cars are trailer bogies. Each diesel multiple unit has two sets of auxiliary power supply units under the ITR cars which generates three-phase 380V AC and additional 220V AC.^[3]

Formation[]

Operations[]

The PNR Hyundai Rotem DMU fleet was first unveiled on June 15, 2009, and was labeled "PNR FilTrack."^{[citation needed]} It entered service on July 14, 2009, coinciding with the launch of the new Philippine National Railways system and logo.^[1] It was used for Commuter Express services running from Tutuban to Bicutan. The line eventually was extended to Sucat and up until Alabang on April 19, 2010. Plans were made for the possible upgrade of the trains in 2011, however, due to the procurement of the 203 series as the new main vehicles, the plan was scrapped.^[5]

The trains are currently being used in Metro North Commuter services running from Governor Pascual station to Bicutan.

As of December 2021, two sets are currently active and are serving the Metro North Commuter (Gov. Pascual-Bicutan) Line.

Refurbishments[]

In July 2015, the then-Department of Transportation and Communications (later the Department of Transportation) conducted a bidding for the refurbishment of nine vehicles, equivalent to three sets.^[3][8] However, after the bidding period ended in September 2015, no new reports have surfaced in this refurbishment.

In line with the delivery of the new trainsets from PT INKA, in November 2019, Rotem DMU Set 06 and Set 05 received their new livery. The mesh wires (window grills) were removed after the replacement of the windows from glass to polycarbonate sheets.^[9][10]

Incidents and accidents[]

• On April 29, 2011, DMR-11 of the original DMU Set 06 collided with a Coca-Cola truck at Manalac Crossing located in Tanyag, Taguig.^[11]
• On May 19, 2014, a DMU train collided with a jeepney in the Balic-Balic railroad crossing while operating a southbound train. A person was dead and more than 6 are injured. The accident caused delays in the train operations.^[12]
• On April 29, 2015, DMU Set 03 derailed between EDSA railway station and Nichols railway station. There were 50 reported injuries, mostly minor cases.^[13] The incident was caused by missing parts of the railtracks that were stolen.^[14] This however, prompted PNR operations to be suspended on May 5, 2015, to conduct safety tests by PNR and TÜV Rheinland.^[15] The operations of the PNR resumed on July 23, 2015.^[16]
• On January 1, 2020, DMU Set 05's windshield was shattered due to a stoning incident while performing an MNC Trip at Caloocan.^[17] The glass window was replaced with polycarbonate the day after the incident. It was also found that a group of minors were the ones who did the crime.^[18]
• On June 3, 2020, DMU Set 06 rammed a car at Abad Santos Railroad Crossing in Tondo, Manila. The crossing barrier was not down when the accident happened. The train dragged the car for about 10 meters.^[19]
• On September 2, 2021, a DMU train rammed a blue car at the Piy Margal Railroad Crossing in Manila despite early warning by the crossing keepers. No injuries were reported. The PNR management is yet to release a statement about the absence of barriers at the railroad crossing,^[20] particularly at the southbound lane.
