It is the first Filipino-made train designed locally with parts imported from abroad. It was officially turned over to the Philippine National Railways on June 20, 2019.

Background

The development of the Hybrid Electric Train (HET) is the project of the Metals Industry Research and Development Center (MIDRC) of the Department of Science and Technology of the Philippine government in partnership with the Philippine National Railways (PNR).[1]

The Hybrid Electric Train project began in 2012, with the designing of the train commencing the following year.[2] The bidding out process for the manufacture of the first train took place in 2013, with the manufacturing of the train taking place from 2014 to 2015.[3] The project was introduced to the public and the media in June 2016.[4]

The train was developed by ten Filipino engineers and technicians from MIDRC led by head engineer Pablo Acuin.[5]

Specifications

The Hybrid Electric Train is a hybrid electric vehicle partly run by electricity and partly run by diesel.[6] The train has 260 lead acid batteries which is used to run the train and operate the train's automatic doors, air-conditioning and CCTV systems.[2] It is convertible to be able to make use of lithium battery.[6] The train makes use of regenerative braking technology converting and storing kinetic energy as electricity that would otherwise be lost every time the train slows down and also hosts a diesel-powered generator.[2]

Each train set has five non-articulated train cars measuring 12 m (39 ft) long, 2.85 m (9.4 ft) wide, and 4.432 m (14.54 ft) high with one double-sliding doors on each side of each car[7], which can carry 220 passengers each at 50 kilometers per hour (31 mph).[8][9]Four of the train cars in the train will carry passengers while the frontmost car serves as a locomotive that contains the driver's cab and a generator. The train does not require catenary lines to operate due to it being powered with its own generator and batteries.[3]

The train also has an automatic stop safety features that would activate in an event of a strong earthquake.[5]

The MIDRC contracted local bus and truck manufacturer Fil-Asia Automotive and Industries Corp. to build the trains. Fil-Asia in turn outsourced the motor, chassis, engine, motor, axle, and wheels from outside of the Philippines to be able to manufacture the Hybrid Electric Train.[2]

Operational history

The first commercial operations of the Hybrid Electric Train began on May 6, 2019. It is currently being used in the Alabang-Calamba Line once a day with its horn and headlights changed and modified by PNR themselves.[10][11] The train was officially turned over to the Philippine National Railways on June 20, 2019.[12]

Future

According to DOST Secretary Fortunato Dela Pena, the DOST will find private sectors that will manufacture the rolling stock of the HET before Rodrigo Duterte ends his term as President in 2022.[13]
