North–South Commuter Railway

The North–South Commuter Railway (Daambakal Pangkomyuter na Hilaga–Timog; NSCR), also known as the Clark–Calamba Railway, is a 147 km commuter rail system under construction on the island of Luzon in the Philippines. Running from New Clark City in Capas, Tarlac, to Calamba, Laguna, with 36 stations and four services, the railway is designed to improve connectivity within the Greater Manila Area and will be integrated with the railway network in the region.

Originally planned in the 1990s, the railway project has had a tumultuous history, being repeatedly halted and restarted for various reasons. The first proposals were the 32 km "Manila–Clark rapid railway" with Spain in the 1990s, alongside the "Manila–Calabarzon Express". During the 2000s, the Northrail project with China was initiated but discontinued in 2011 due to allegations of overpricing. The railway's current incarnation began development in 2013. The project's initial phase was approved in 2015, and construction began in 2019.

Expected to cost ₱873.62 billion, the line is the most expensive railway transportation project in the country. The entire system is expected to be completed by 2031.

Background
During the Spanish and American colonial periods, the Manila Railway Company, later the Manila Railroad Company (MRR), operated various local trains between Manila and its neighboring provinces. By the 1920s, trains had run from Tutuban to Naic in Cavite, Pagsanjan in Laguna, Montalban in Rizal, and Bulacan. The network was heavily damaged in the Battle of Manila during World War II, but was mostly reestablished after the war. MRR was succeeded by the Philippine National Railways (PNR) on June 20, 1964.

On April 6, 1970, PNR inaugurated the Metro Manila Commuter Service, which started at Manila North Harbor and ended in Biñan station in Laguna. After numerous expansions, the commuter service served thousands of daily riders in its system and had an expansive network in and out of Metro Manila. In 1978, at the request of the Philippine government, the Japan International Cooperation Agency (JICA) conducted a study on the electrification of the commuter service. The plan was made to keep up with the increasing demand for transportation in the region. It called for the replacement of the diesel-run trains and the electrification of the PNR commuter line. Two experts from the Japanese National Railways were sent to conduct the study.

Services north of Manila started to decline in the 1980s. However, commuter services were briefly extended to Malolos starting in 1990 under the Metrotren project but later ceased in 1997. Since then, railway services have been mostly confined to the south, with the contemporary Metro Commuter Line being predominantly aligned to the South Main Line.

Proposals in the 1990s
On April 28, 1994, President Fidel Ramos signed an executive order designating Clark Air Base, a former American airbase, as the premier international airport, with the support of the Bases Conversion and Development Authority (BCDA), while the other agencies also supported the development, and in September of the same year, President Ramos signed a memorandum of agreement with Juan Carlos I of Spain for the construction of a railway line from Manila to Clark. This would be known as the Manila–Clark rapid railway system (MCRRS). A joint venture agreement was entered into on June 10, 1995, between BCDA, PNR, Philippine companies DMCI Holdings and Fort Bonifacio Development Corporation, and Spanish firms with Construcciones y Auxiliar de Ferrocarriles, Entrecanales y Tavora, Cubiertas y MZOV, (both companies later merged to form Acciona) and Cobra Instalaciones y Servicios, S.A., as well as other investors. The agreement also established the North Luzon Railways Corporation (NLRC) for the purpose of constructing, operating, and managing the railroad system on August 24. The NLRC then entered into an engineering, procurement and construction contract with the Spanish Railways Corporation on February 7, 1996. Meanwhile, in 1997, Ayala Land proposed the construction of a railway known as the Manila–Calabarzon Express (MCX). Its initial phase involved the rehabilitation of the railway from Caloocan to Calamba and eventually the construction of spur lines to Carmona and Canlubang under a build–own–operate scheme.

Studies indicated that the MCRRS project was planned to unfold in four phases. Phase 1, spanning 100 km, was set to connect Fort Bonifacio, including a proposed intermodal station in Bonifacio Global City, to the Clark Freeport and Special Economic Zone. Phase 2 aimed to extend the line 50 km to Subic Bay. Phase 3 planned for a 170 km extension to San Fernando, La Union. Phase 4 proposed an additional 200 km extension from San Fernando to Laoag and an additional 55 km spur line to San Jose, Nueva Ecija. Both proposals were subsequently included in the Metro Manila Urban Transportation Integration Study (MMUTIS).

The contract between the NLRC and the Spanish Railways Corporation was terminated on August 14, 1998, after the parties disagreed on the source of funding for the project. Despite the contract termination, in September 1999, the National Economic and Development Authority (NEDA) approved the MCRRS, with the initial phase covering a segment from Caloocan to Calumpit. The source of funding was to be the Obuchi Fund from the Japan Bank for International Cooperation (JBIC). The consortium was also now joined by Japanese companies including Fil Estate Management, Nishimatsu Construction, and Mitsui & Co. Pre-construction activities such as right-of-way clearing and relocation of affected informal settlers began, but a presidential directive later halted the clearing activities and the JBIC loan was not granted. Ayala Land was subsequently excluded from the MCX as the government opted to fund the railway construction also through the Obuchi Fund, opening the project for bidding to private developers. By 2001, the Japanese government was considering funding the project.

Another study about the integration of Metro Manila's railway network by JICA in 2001 proposed the through-operation of both railways in two options, such as an elevated section running 10 kilometers on the existing PNR old right-of-way or an underground section running 7 kilometers from Tayuman to Vito Cruz. According to SIRNMM, the proposed indicative length, which would have run from Tayuman to Marilao, was 17.0 kilometers, while both options for MCX were to be 46.2 (elevated) or 43.2 (underground) kilometers from Tayuman to Cabuyao. However, the plans would never materialize.

Northrail
Under the presidency of Gloria Macapagal Arroyo, the MCRRS was succeeded by the Northrail project, a 320 km railway system from Caloocan to San Fernando, La Union. The Northrail project's 80 km phase 1 involved the upgrading of the existing single track to an elevated dual-track system, converting the rail gauge from narrow gauge to standard gauge, and linking Manila to Malolos in Bulacan and further on to the Clark Freeport and Special Economic Zone and the Clark International Airport. The first segment of phase 1 covered the 32 km railway from Caloocan to Malolos. Succeeding phases followed the MCRRS masterplan, although Phase 4 was removed, Phase 3 was rebranded as Phase 4, and the section between Fort Bonifacio to Caloocan was rebranded as Phase 3, while Phase 2 was unchanged. Its southern counterpart, the Southrail project, involved the rehabilitation of the entire South Main Line from Calamba to Legazpi, Albay, with an extension to Matnog. Meanwhile, the Northrail–Southrail Linkage involved the rehabilitation of the existing Metro Commuter Line from Caloocan to Calamba, creating a link between the two systems.

On September 14, 2002, a memorandum of understanding was signed by NLRC and China National Machinery and Equipment Group (CNMEG) for the project. It was later approved on August 5, 2003. The project was estimated to cost around US$500 million, and the funding was to be covered by a US$400 million loan from the Export–Import Bank of China, and the rest to be shouldered by the government through BCDA and NLRC. The Southrail project was also expected to be financed by loans from China, while the linkage project was to be financed by South Korea. While the plans for Southrail were not realized, the initial phase of the linkage project from Caloocan to Alabang was completed in December 2010.

Before Northrail's construction could start, the project became embroiled in controversy as the Philippine Senate raised concerns about alleged corruption in the project. Senator Franklin Drilon commissioned a study from the University of the Philippines, which recommended the cancellation of the railway's construction, citing anomalies in the bidding process and the Buyer Credit Loan Agreement (BCLA) with Exim China. Despite the controversy, preparatory construction began in early November 2006. Civil and design works started in October 2007. However, CNMEG reportedly demobilized from the project on July 1, 2008, due to differences on engineering and construction standards, although this was later retracted.

Due to delays in the construction work, it was soon renegotiated with the Chinese government. Construction temporarily continued in January 2009 with the support of the North Luzon Railways Corporation. However, the project would be shelved in March 2010 due to persisting legal issues and allegations of overpricing and corruption. In 2011, Northrail was cancelled by the government under the presidency of Benigno Aquino III. Like the failed Hopewell Project in Bangkok, a few structures had been completed by the time of its cancellation. The government contemplated reusing the completed structures from the project, but ultimately, this was not implemented.

In September 2011, the government expressed its interest to restart the project with China reportedly open to reconfigure the project. In March 2012, the Philippine Supreme Court authorized a lower court to hear the case for voiding the contract. Instead of paying the US$184 million owed by the government in 2012, the Department of Finance was to pay Exim China four installments of US$46 million from September 2012 onwards. In August 2012, the Chinese and Philippine governments agreed to "disengage" from the project, although the Philippine government was still obligated to pay the corresponding loans. On November 6, 2017, DOTr, BCDA, and NLRC reached an out-of-court settlement with Sinomach (formerly CNMEG), resolving the five-year dispute. It saved the government ₱5 billion in potential payment of claims to Sinomach and hundreds of millions of pesos in legal fees and arbitration costs.

The Governance Commission for GOCCs (GCG) ordered the deactivation of NLRC in May 2019. According to GCG, the company was "not producing the desired outcomes, no longer achieving the objectives and purposes for which it was designed and created, and not cost efficient and does not generate the level of social, physical and economic returns vis-à-vis the resource inputs." On October 19, 2023, NLRC was formally abolished, with the BCDA to act as the administrator and liquidator of NLRC and settle its liabilities.

Development
With the termination of the Northrail project, the Department of Transportation and Communications considered restarting the project by commissioning a feasibility study by CPCS Transcom Ltd. of Canada. Part of the study examined having a Malolos–Tutuban–Calamba–Los Baños commuter line. The feasibility study was still ongoing when the NEDA included the project in the Metro Manila Dream Plan, which it approved in 2014. JICA also conducted a new study a year before a new transport infrastructure master plan was published. This plan calls for an airport express railway linking Ninoy Aquino International Airport in Metro Manila to Clark International Airport with a total length of 99.4 kilometers. The government also examined building a railway on top of the North Luzon Expressway instead of using the PNR right of way, which was still allocated for the Northrail project at the time.

By August 2014, the Northrail project was reinitiated as the North–South Commuter Railway and awaited approval. On February 16, 2015, the NEDA board, chaired by President Aquino, approved the NSCR Phase 1 as part of the North–South Railway Project (NSRP). The NSCR, a part of the NSRP north line's first phase, was a 37 km electrified narrow gauge commuter railway from Tutuban to Malolos, funded through overseas development assistance. Other components of NSRP masterplan include the reconstruction of the existing Metro Commuter line and the reestablishment of long-haul services to northern and southern Luzon, all of which were to be funded through a public–private partnership (PPP) scheme. After President Aquino met with Japanese Prime Minister Shinzo Abe in Japan in June 2015, Abe expressed his commitment to fund the project. On November 19, 2015, representatives of both countries exchanged notes on the project in the presence of Abe and Aquino. JICA was chosen by the Japanese government to look into financing the project, and on November 27, JICA and the Department of Finance signed a loan agreement worth ₱97.3 billion ($1.99 billion) for the financing of the first phase.

The succeeding Duterte administration included the project under its flagship Build! Build! Build! Infrastructure Program. In addition, numerous changes to the project were made. The railway's gauge was changed to standard gauge, and the railway was extended to New Clark City. The south commuter line, now placed under the NSCR project as the North–South Commuter Railway Extension Project (NSCR-Ex), was shifted from a PPP scheme in favor of overseas development assistance from Japan and later the Asian Development Bank (ADB). The long-haul segment of the south line was now under a new initiative known as the PNR South Long Haul. On June 25, 2017, transportation secretary Arthur Tugade announced the new name for the project and unveiled the locations of the first five stations during a press tour of the old PNR line.

On January 21, 2019, a loan agreement worth ₱80.47 billion (US$1.54 billion) for the NSCR-Ex, which includes the PNR Clark 2 and Calamba sections, was signed by JICA and the Department of Finance (DOF). Another loan agreement worth ₱66.6 billion (US$1.3 billion) for the NSCR-Ex project was signed on July 11 by the ADB and DOF. JICA would finance the electrical and mechanical systems as well as the trains for the PNR Clark 2 and Calamba sections, while ADB would finance the civil works.

The loan for the civil works of PNR Calamba, worth ₱227 billion (US$4.3 billion), was approved by the ADB on June 9, 2022. The loan agreement was signed by President Rodrigo Duterte and ADB on June 16. Two more loan agreements were signed on February 9, 2023, during the working visit of President Bongbong Marcos in Japan.

Construction
Pre-construction works such as clearing of the right of way started on January 5, 2018. The railway is being built in three phases and divided into two primary sections:


 * PNR Clark — This is the northern section of the NSCR. Construction was divided into two phases. PNR Clark 1 involves the 38 km Tutuban–Malolos railway, while PNR Clark 2 involves the 53 km Malolos–Clark railway. The 91 km railway line, when fully completed, will run from Tutuban station in Manila to New Clark City station within the Clark Freeport and Special Economic Zone, with a link to Clark International Airport.
 * PNR Calamba — Also known as PNR Clark Phase 3, PNR Calamba is the southern section of the NSCR. It involves the reconstruction of the existing Metro Commuter Line as an electrified standard gauge railway with elevated, at-grade, and depressed sections. The 56 km railway will run from Solis station in Manila to Calamba station in Laguna.

PNR Clark 1 broke ground on February 15, 2019, followed by PNR Clark 2 on September 18, 2021. Meanwhile, construction of NSCR South began on July 3, 2023, following the closure of Alabang–Calamba commuter services the previous day. To fast-track the construction of NSCR South, the rest of the Metro Commuter Line services temporarily closed on March 27, 2024. The closure would fast-track construction by eight months, saving ₱15.18 billion in costs.

On March 15, 2024, the Department of Transportation announced the completion of the 14 km segment of PNR Clark 1 from Malolos to Bocaue. Nevertheless, the remaining segments are 37.30-percent complete as of the month, while PNR Clark 2 is at 25.76 percent. The partial opening was initially set for 2022, but this deadline was not met, presumably due to several factors including but not limited to right-of-way acquisition, and the COVID-19 pandemic. Instead, it expects partial operations by 2028 and full operations by 2031. Also, the transportation department said it was facing a challenge in the right-of-way, particularly in the Valenzuela to Sucat segment.

Route
The North–South Commuter Railway will comprise two sections corresponding to the Philippine National Railways' old main lines. The first is the 91 km fully-elevated PNR Clark which is being built over the mostly-defunct North Main Line in northern Metro Manila and Central Luzon. The construction of PNR Clark is further subdivided into two sections: the 38 km PNR Clark 1 between Tutuban and Malolos, and the 53 km PNR Clark 2 from Malolos to New Clark City. The second component is the 56 km PNR Calamba which will use the existing PNR Metro Commuter Line right of way between Tutuban and Calamba, which were historically parts of the South Main Line and will have elevated, at-grade and depressed sections.

Services
There are four classes of services on this line. The following are:
 * Commuter is the basic commuter rail service and has the least priority. It stops at all stations within its route. There are three routes planned for this class; Tutuban–New Clark City, Tutuban–Calamba, and Clark International Airport–Calamba. The maximum speed for this service will be 120 km/h for the entire line.
 * Commuter Express is the limited-stop service for the line, succeeding the Commex service during the Metrotren era in the early 2000s. Although it will run faster than regular commuter trains, it will still use the same routes and rolling stock.
 * The Airport Limited Express is the temporary designation for the planned airport rail link and limited express service between Clark International Airport and Alabang station. As the flagship NSCR service, it will use dedicated rolling stock complete with intercity-grade amenities plus baggage space for people arriving from the airport. It will have a maximum speed of 160 km/h along the NSCR North., the final name for the service is yet to be determined.
 * Subway through-service is the proposed augmentation between the NSCR and the Metro Manila Subway. It will serve the southernmost areas of Metro Manila and neighboring Laguna, branching from the subway line at FTI station while the remainder of the line will go towards the direction of NAIA Terminal 3 in Pasay. It will use the Subway trainsets instead of the NSCR ones, although both are from the sustina family.

Extensions and additional stations
The Metro Manila Dream Plan proposed a 38 km branch line that will split in Angeles City. The line will have 12 stations and shall end in Tarlac City. The study also proposed a 47 km extension of the NSCR to Batangas City. This will be built parallel to the PNR South Long Haul project which was approved in 2017, with the line being a single-track, standard gauge line without electrification, and will be built at-grade similar to the present PNR network. The PNR has also requested for a feasibility study for a commuter line connecting Tarlac City and San Jose, Nueva Ecija in 2019. The length of the line and the number of stations will be determined once a proposal has been submitted. Another proposed southward extension to Pansol in Calamba, Laguna was proposed by a 2019 JICA report.

The North–South Commuter Railway will also have provisions for infill stations: Malabon, Valenzuela Polo, Tabing Ilog, Tuktukan, and Malolos South.

Infrastructure
NSCR will be the first commuter rail system in the country to be mostly grade-separated. Trains are designed to run on tracks at a design speed of 120 km/h for regular trains and 160 km/h for airport express trains.

Station layout
All stations will have a standard layout, with a concourse level and a platform level. The stations are designed to adhere to both Philippine and Japanese standards. Stations will either have island platforms or side platforms with platform screen doors. The stations are designed to be barrier-free, and trains shall have spaces for passengers using wheelchairs. Historical stations will be preserved. All stations will have access to intermodal facilities. The FTI station in particular will be connected to the Taguig Integrated Terminal Exchange.

Rolling stock
The North–South Commuter Railway will have two types of rolling stock: commuter trains and airport express trains. Except for wheelchair spaces, the commuter trains will have a capacity of 2,242 passengers. The express trains, on the other hand, will have a capacity of 392 passengers. A total of 464 electric multiple unit traincars have been procured to operate on the line, with 408 of these being the 8-car EM10000 class trainsets to be built by the Japan Transport Engineering Company (J-TREC), successor to the Tokyu Car Corporation that provided rolling stock to the Philippines from 1955 to 1976. The trainsets were previously named as the Sustina Commuter at the time of purchase, and are based on JR East commuter stock such as the E233 series but adapted to standard gauge. The trains are also designed to be interoperable with the Metro Manila Subway. The trainsets have been designated as the EM10000 class in October 2021.

The procurement for the 56 airport express trainsets began on February 26, 2021, with a suggested preliminary design based on the E259 and E353 series being published on the same day. On May 10, the Department of Transportation later announced that it would acquire the airport express trainsets from Japanese manufacturers. After several months of delays and rescheduling, three bidders have submitted their designs on October 15: Kawasaki Heavy Industries and Sojitz, Marubeni and Stadler Rail, and Mitsubishi and Construcciones y Auxiliar de Ferrocarriles (CAF). On August 24, 2023, Mitsubishi and CAF, also the manufacturers of the LRTA 13000 class trains on the LRT Line 1, were awarded the contract for the express trains.

Signaling
Initially, the PNR Clark 1 section of the line was set to use a communications-based train control (CBTC) system. Subsequent design documents planned for the installation of the European Train Control System (ETCS) instead. Its Level 2 system would be used for the NSCR. The subsystems consist of automatic train control (ATC), automatic train protection (ATP), automatic train supervision (ATS), train detection through track circuits, and computer-based interlocking, with provisions for automatic train operation (ATO).

Hitachi Rail STS, Hitachi's Italian subsidiary, was tapped in November 2022 to provide the signaling equipment for Phase 1 (Tutuban–Malolos) as part of a contract package covering electrical and mechanical systems, and track works. Meanwhile, Alstom was tapped in March of the same year to supply its Atlas 200 solution for Phase 2 (Malolos–Clark) and the NSCR South (Solis–Calamba). Alstom was previously awarded in a contract to supply its Atlas 100 Level 1 solution for the LRT Line 1 in 2016.

Tracks
The line will feature an Elastic Sleeper Direct Fasten (ESDF) type ballastless track with concrete sleepers in the mainline and plastic/fiber-reinforced foam urethane railroad ties on turnouts in the mainline and depot. Continuous welded rails will be employed on the mainline, while jointed rails with fishplates will be employed in the depot. 60 kg/m rails will be employed in the mainline while rails built to the JIS 50N rail profile will be used in the depot.
