The Hybrid Electric Train (HET) is a hybrid diesel multiple unit of the Philippine National Railways (PNR) in the Philippines. It was developed by the Metals Industry Research and Development Center (MIRDC), an attached agency of the Department of Science and Technology of the Philippines, and the car body was made by Fil-Asia Automotive and Industries Corp. BackgroundThe hybrid electric train was conceived in 2012. Back then, the DOST was helping PNR retrofit its fleet of locomotives. But DOST decided later to develop a new train instead of retrofitting the trains. To do this, the DOST assembled a team of engineers from various fields. In 2013, the team came up with a design for a hybrid electrical train. After coming up with the design, the team started looking for a local fabricator who can make the train coaches. Fil-Asia Automotive and Industries Corp, which makes bus bodies and special trucks won the bidding to fabricate the train coaches. It took 2 years to integrate the train's different components and by the end of 2015, the trains were ready for testing. It took another 2 years and 5,000 kilometers of performance tests to determine the HET’s reliability, availability, maintainability and safety before the DOST was ready to turn over the train to the PNR in 2018. OverviewThe train is five-car formation, one of them is a space to install equipment such as a diesel generator set and the battery racks, and it cannot be used by passengers. CarbodyThe carbody structure utilizes mild steel hollow rectangular tubes, having the capability to withstand the loading without any permanent deformation. The window is fitted with a wire mesh to protect it from stones. InteriorThe interior of the train is based on white. The color of the seat is sky blue and made of fibre-reinforced plastic. The floor is high and steps are provided at the door. Hybrid systemThe diesel engine generates electricity, and the generator outputs a three-phase AC 460V. The generator is used as the main power source.
