The LRTA 13000 class is a class of fourth-generation high-floor light rail vehicles (LRV) of the Light Rail Transit Authority servicing the LRT Line 1, manufactured by CAF. Purchased in 2017 with Japanese funding as part of the Cavite extension of the line, the trains entered service in July 2023 to replace the aging first-generation 1000 class trains.

It is the first LRV in the system with 5 digits in the body number due to the class fleet exceeding 99 units, in comparison to the older fleet.

Operational history

=Purchase=

In 2013, feasibility studies were conducted by the Japan International Cooperation Agency (JICA) for a southward extension of the LRT Line 1 to Cavite. It determined that once the extension was completed, sixty-one trains would be required for operation, but thirty-one of those are existing ones. Therefore, JICA proposed the purchase of thirty new trains to meet growing demand.{{Sfn|JICA|2013|p=5-3}}

On October 16, 2015, the Department of Transportation and Communications (DOTC) invited train manufacturers to tender for the purchase of 120 light rail vehicles; Japanese companies were only allowed to bid.{{Cite news|title=Only Japanese firms may bid for LRT-1 train supply deal – DOTC|first=Keith Richard D.|last=Mariano|work=GMA News|date=October 16, 2015|access-date=December 30, 2021|url=https://www.gmanetwork.com/news/money/companies/540907/only-japanese-firms-may-bid-for-lrt-1-train-supply-deal-dotc/story/}} It subsequently identified Marubeni and Sumitomo Corporation as prospective bidders.{{Cite news|first=Darwin G.|last=Amojelar|title=Marubeni, Sumitomo bidding for 120 new cars of LRT 1|url=https://manilastandard.net/business/199311/marubeni-sumitomo-bidding-for-120-new-cars-of-lrt-1.html|work=Manila Standard|date=February 14, 2016|access-date=October 26, 2021}} However, in April 2016, the DOTC announced a failed bidding as none of them submitted proposals.{{Cite news|title=Bidding for new LRT 1 trains fails |first=Darwin G. |last=Amojelar |date=April 3, 2016 |work=Manila Standard |url=https://manilastandard.net/business/202806/bidding-for-new-lrt-1-trains-fails.html |access-date=June 13, 2024}}

On July 19, 2023, the trains were inaugurated by President Bongbong Marcos. The first train set entered revenue service the next day. More trainsets from the 13000 class are expected to be incrementally entered into service, with one additional train set every week until every trainset enters service. All trains are expected to enter service by the fourth quarter of 2024, once the Cavite Phase 1 extension is opened.{{Cite news|title=New, state-of-the-art train sets await LRT-1 riders starting July 20 |first=Aaron |last=Recuenco |date=July 19, 2023 |url=https://mb.com.ph/2023/7/19/new-state-of-the-art-train-sets-await-lrt-1-riders-starting-july-20 |work=Manila Bulletin |access-date=July 19, 2023}} As of December 23, 2024, 23 trainsets have been deployed for revenue service.{{Cite AV media |title=Good news, mga ka-riles 📣 More 4th Generation trains are now ready to serve #LRT1 passengers in time for the holiday season! 23 (out of 30) are already running along the main line for commercial service.

=Water leaks=

A few months before the trains entered service, Transportation Undersecretary for Railways Cesar Chavez disclosed on February 16, 2023, that water leaks were found in eighty LRVs that were delivered to the Philippines. He further disclosed that as a result, these could not be used in mainline operations, and the government suspended payments to Mitsubishi and CAF in July 2022.{{Cite news |title=Nearly all train cars delivered for LRT-1 Cavite Extension defective, says DOTr official |first=Xianne |last=Arcangel |work=CNN Philippines |date=February 17, 2023 |url=https://www.cnnphilippines.com/news/2023/2/17/lrt-1-cavite-extension-trains-defective.html |access-date=February 17, 2023 |archive-date=February 18, 2023 |archive-url=https://web.archive.org/web/20230218032613/https://www.cnnphilippines.com/news/2023/2/17/lrt-1-cavite-extension-trains-defective.html |url-status=dead }}

Chavez admitted that as a result of travel restrictions caused by the pandemic, the DOTr was unable to send inspection teams to inspect the trains for any defects, while these were still undergoing factory acceptance tests. These defects were later fixed through a comprehensive roof rectification plan.{{Cite AV media|title=Mga depektibong bagon ng LRT-1, isasailalim sa roof rectification process – DOTr |lang=fil |url=https://www.youtube.com/watch?v=faepDmkj-lQ |trans-title=Defective train cars of LRT-1 to undergo roof rectification process – DOTr}}

==Front cab variations==

The fourth-generation trains vary in two frame colors. The first two sets (Trainsets 1 & 2), built in Spain, have a red-painted "forehead" above the windshield and LED sign, while sets 3 to 30, built in Mexico, received a black "forehead".

Some train sets has varying signage data as well; train sets that arrived and/or were certified prior to the renaming of Roosevelt station to Fernando Poe Jr. station retained its destination signage. Later train sets feature the correct destination name which is noted to scroll instead of being static. All train sets had its signage data been updated in preparation for opening of the Cavite Extension Phase 1.

As opposed to the older rolling stock, the 13000 class includes hand straps aside from safety handrails installed above the train floor.

The trains are also the first in the Philippines to feature a specially-made wheelchair-compatible space or passenger with restricted mobility (PRM) areas, located closer to the driver's cab as compared to the 1100 class and 1200 class where it is located near the articulation.{{Cite web|author=officialLRT1|title=LRMC welcomes new LRT-1 Generation-4 trains

Longitudinal seating is present in the 13000 class, as per other train classes in the system.

Like the 1100 class and 1200 class, there are four pocket-type doors per side per car.{{Sfn|DOTC|LRTA|2015|p=99}} For the driving cars, one door is installed on the side of the driving cab.

Each LRV has three inside-frame bogies consisting of two motorized bogies at the ends and a Jacobs trailer bogie under the articulation. Semi-permanent couplers are installed at the ends of every light rail vehicle, except for the driving cab section of the head car.{{Sfn|DOTC|LRTA|2015|p=126}}

These trains are easily recognizable by their distinctive braking sounds, which produce a screeching noise when stopping. This trait was not present in earlier train class sets, even when they were first introduced.

Like the 1100 class and 1200 class, each LRV consists of four {{convert|105|kW|hp|adj=on}} 3-phase AC induction motors, driven by variable-voltage/variable-frequency drive (VVVF) inverters with insulated-gate bipolar transistors (IGBT).{{Sfn|DOTC|LRTA|2015|p=149}} Auxiliary power is sourced from a static inverter, a low-power DC voltage supply, and batteries.{{Sfn|DOTC|LRTA|2015|p=152-153}}
