The Metro Manila Subway Sustina EMUs are electric multiple unit trains being ordered by the Department of Transportation for the Metro Manila Subway project. A total of 240 railcars belonging to the sustina (ja) family were ordered from the Japan Transport Engineering Company (J-TREC) in 2020. These trains are yet to be constructed as of September 2022 as another derivative of the sustina, Philippine National Railways' EM10000 class, is being built at the J-TREC plant in Yokohama.

Background[edit]

Main article: Metro Manila Subway

Plans for an underground subway have been in discussion with the Overseas Technical Cooperation Agency since 1973. The main argument for using an underground rail line in Metro Manila during that time was to allow a lower footprint which would mean, especially in the densest areas of the city such as San Nicolas and Binondo. The original trainsets for the so-called Manila Rapid Transit Railway (RTR) Line 1 as published in 1976 would use standard gauge track and 750 V direct current third rail power which would be collected by a contact shoe, that is if the Marcos government opted to use the so-called "two-rail" system which is the contextual term for conventional rail in contrast to a monorail which was also proposed for the line. Its specifications would be 2.88 by 4 meters (9.4 by 13.1 feet) width and height, respectively, as well as a length of 20 meters (66 ft). This project however never materialized for another 40 years until the approval of the.

Specifications for the new Metro Manila Subway project were released to the public in December 2019. The conceptual design was based on the Tokyo Metro 10000 series, adopted to standard gauge. The external measurements are based on the STRASYA standard conceptualized in 2004 in which it is 2.95 meters (9 ft 8 in) in width excluding certain accessories, 4.15 meters (13 ft 7 in) in height with pantograph lowered, and 20 meters (65 ft 7 in) in length.[3]

Production[edit]

Orders were finalized on December 21, 2020 with Japanese manufacturer J-TREC chosen as its supplier. Production has yet to commence.

Service[edit]

The trainsets are expected to enter service by 2025.

Features[edit]

Both the Subway trainsets and its sister class the EM10000 are part of the larger sustina family, named after the patented manufacturing process used in the construction of the trainsets. Its cab design follows that of the E233 series while minor aspects of its exterior also follow the newer E235 series. It is distinguished from the EM10000s by having a black and blue livery.

Signalling[edit]

The trains shall use both communications-based train control (CBTC) and European Train Control System (ETCS) systems. Throughout the Subway main line from East Valenzuela to Senate–DepEd, the trainsets will use SPARCS CBTC by Nippon Signal, which was contracted by bidder Colas Rail. These trainsets are also effectively ETCS Level 0 compliant within this segment. At Senate station, signalling equipment will be switched from CBTC to ETCS Level 2 in order to become interoperable with the NSCR between FTI and Bicutan stations, especially with its planned extension to the NSCR terminus at Calamba.

10-car trainset[edit]

A 10-car variant has been announced in the bid documents for contract package CP107 which specifies the rolling stock requirements. These trainsets have a tare weight of 325 metric tons (320 LT; 358 short tons; 717,000 lb). The platform design of the stations has already been aligned asymmetrically in order for easier construction of the platforms that would allow 10-car trains.

  2. ^ An additional order for 304 cars (38 sets) for Phase 2 and 3 was awarded to the same manufacturer, but due to differences in the traction control system in which the 38 sets uses the Hybrid SiC–VVVF system while the first 13 sets uses the IGBT–VVVF system based on bidding documents, the type is yet to be determined.
