PNR North Main Line

{{See also|Philippine National Railways#History}}

The railroad network in Luzon, predecessor to today's Philippine National Railways, was first proposed on August 6, 1875. To the north of Manila are two main lines, one leading to Laoag, Ilocos Norte and the other leading to Tuguegarao, Cagayan. The system was approved by the Spanish East Indies government in 1880, but construction did not commence until 1887 due to the lack of a concession operator.{{Cite web |first=Juan |last=Peris Torner |title=Ferrocarril de Manila a Dagupan – Plan General de Ferrocarriles de la Isla de Luzón – Filipinas |url=https://www.spanishrailway.com/ferrocarril-de-manila-a-dagupan-plan-general-de-ferrocarriles-de-la-isla-de-luzon/ |website=Ferrocarriles de España |date=November 13, 2018 |access-date=October 21, 2020 |language=Spanish}} Unlike the South Main Line which was built to its planned terminus in Legazpi, Albay, the North Main Line network never reached its intended termini in Laoag for the northwestern line and Tuguegarao for the northeastern line.

The Manila Railway Company, Limited was created on June 1, 1887, and construction began. Initial site inspection was presided by Lieutenant Colonel José Gago y Palomo (1849–1908), who was renowned for building fortifications and trails in Mindanao for Spanish Army General Valeriano Weyler.{{Cite web |title=Gago Palomo, José |url=http://dbe.rah.es/biografias/10016/jose-gago-palomo |publisher=Real Academia de la Historia |language=es |access-date=May 20, 2021 }} According to Gary Satre on an investigative article in 1999, the use of 3 feet, 6 inches gauge was made both as a cost-cutting measure and to allow tighter curves in order to suit the island's mountainous terrain.{{Cite journal |last=Satre |first=Gary |title=The Cagayan Valley Railway Extension Project |url=https://www.ejrcf.or.jp/jrtr/jrtr22/F38_Satre.html |journal=Japan Railway & Transport Review |volume=22}} One of the main obstacles in the construction stage is crossing the Rio Grande de Pampanga, after which a box truss bridge was built.

At the same time, several tank locomotives were ordered by the Manila Railway. This began with an order for 2 Manila Railway Manila class locomotives in 1886 from English manufacturer Hunslet Engine Company. These were later named Manila and Dagupan after the line's two planned termini.{{Cite thesis |last=Corpuz |first=Arturo |title=Railroads and regional development in the Philippines: Views from the colonial iron horse, 1875–1935 |date=May 1989 |publisher=Cornell University |url={{GBurl|id = gOFOPAAACAA|pg = PR1}} |access-date=June 20, 2020}} Between 1888 and 1890, thirty Manila Railway Dagupan class locomotives were ordered from Neilson and Company and Dübs and Company.{{Cite report |first=P. |last=Unson |title=MANILA RAILROAD CO.

Prior to the opening of the full length of the line to Pangasinan, José Rizal was one of the most popular commuters of the early Ferrocarril de Manila a Dagupan. He used the line to recruit potential La Liga Filipina members prior to his exile. On February 23, 1892, he took a train to San Fernando station in Pampanga.{{Cite news |title=San Fernando train station {{!}} San Fernando, Pampanga — Baktin Corporation |language=en-US |publisher=Baktin Corporation |url=http://www.baktincorporation.com/2012/01/san-fernando-train-station/ |archive-url=https://web.archive.org/web/20200928163145/http://www.baktincorporation.com/2012/01/san-fernando-train-station/ |date=January 16, 2012 |access-date=May 26, 2021 |archive-date=September 28, 2020 |url-status=dead}} He then commuted to various other locations in Central Luzon, until he took his last train with a {{Convert|120|km|abbr=on}} trip to Tarlac on June 26. He wrote that the trip took 5 hours, 40 minutes. This was 2 weeks prior to his exile to Dapitan. On November 24, 1892, the line to Dagupan was inaugurated.{{Cite journal |first=Pante |last=M. |date=2014 |title=Mobility and Modernity in the Urban Transport Systems of Colonial Manila and Singapore |journal=Journal of Social History |volume=47 |number=4 |pages=855–877|doi=10.1093/jsh/shu023 }}

Manila Railway trains were used by both the Philippine Revolutionary Army and the United States Army forces during the Philippine–American War. President Emilio Aguinaldo and his cabinet ministers used First Class car Z4 as their primary method of travel on the railroad, especially during their retreat to northern Luzon.{{Cite book |first=Murat |last=Halstead |title=The Story of the Philippines: The El Dorado of the Orient |date=28 April 2014 |publisher=Our Possessions Publishing Co. |place=Chicago, Illinois, USA |isbn=9781499286656 |url=https://archive.org/details/storyphilippine02halsgoog}} On the other hand, the advancing American forces used the Manila Railway to carry freight and Army soldiers.

After the war, the network was repaired and expanded. The British owners were still allowed to operate for the following years, having reorganized into the Manila Railway Company (1906) Limited.{{Cite AV media |title=Sammlung eines Mitglieds des Ersten Deutschen Historic-Actien-Clubs e.V.

By 1909, the Manila Railroad took control of the system, although Horace L. Higgins still leads as its general manager in the country and the Annual Report was still prepared with British conventions. New lines were defined by Insular Government Act No. 1905 as the Northern Lines. This include the Manila–Dagupan main line, the Antipolo branch of the Southern Lines, the Cabanatuan branch, the Fort Stotsenburg branch, and shortline railroads serving the Port of Manila and within Dagupan.{{cite act |type=Act No. 1905 |date=May 19, 1909 |legislature=Philippine Commission |title=AN ACT GRANTING THE MANILA RAILROAD COMPANY CERTAIN ADDITIONAL CONCESSIONS FOR RAILROAD LINES IN THE ISLAND OF LUZON |page= |url=https://lawyerly.ph/laws/view/l91a2 |language=en-US}}

The Baguio Special, the Philippines' first named express train service, was inaugurated in 1911. Originally only stopping at Damortis in Rosario, La Union with a luxury car service heading for the hill station of Baguio, this train started the scramble for a direct rail service.{{Cite AV media |first=George |last=Lane |title=Baguio Special at Manila Station |url=https://www.flickr.com/photos/ssave/31892788040 |work=Far Eastern Review |date=1911 |accessdate=May 21, 2021}} Construction for the Aringay–Baguio line started in 1914 but was never finished and the tunnel leading to the city was never completed, citing British involvement in World War I as the reason.{{Cite news |first=Yolanda |last=Sotelo |title=The saga of Aringay rail line |url=https://newsinfo.inquirer.net/652848/the-saga-of-aringay-rail-line |newspaper=Philippine Daily Inquirer |date=November 26, 2014 |access-date=May 21, 2021}} This later made the Manila Railway's remaining Philippine unit to be absorbed into the Manila Railroad on January 8, 1917, with general manager Horace L.

Under McCoy's leadership, the Manila Railroad modernized its locomotive fleet with the purchase of several American-built tender locomotives over the next few years. Meanwhile, the American Car and Foundry provided both regular passenger and sleeping cars, starting with the new Baguio Night Special service.{{Cite report |title=Report of the General Manager for the Year Ended December 31, 1922 |work=Reports of the General Manager |publisher=Manila Railroad Company |date=March 25, 1923}} After his death in 1923, he was then succeeded by Jose Paez, the first Filipino general manager of the company.

Although the line was damaged after the First Philippines campaign during World War II, the Japanese briefly extended it to Sudipen near the La Union–Ilocos Sur border, some {{Convert|41.6|km|abbr=off|sp=us}} north of San Fernando. After the Second Philippines campaign, the line has been closed.

In 1951, Ramon Magsaysay was appointed as general manager of the Manila Railroad. Under Magsaysay's term as general manager despite being only three months, made the company extend its network to Bacnotan. He would also preside the beginning of the Cagayan Valley extension. Magsaysay later became the President of the Philippines in 1953 and under his term, the Manila Railroad underwent another fleet modernization. Its entire steam locomotive fleet will be replaced by diesel locomotives starting in 1954. In August 1956, the modernization has been completed and all steam locomotives were relegated to maintenance work or retired altogether.{{Cite magazine |title=The Passing of the Steam Engine |magazine=This Week |url=https://www.flickr.com/photos/79691913@N05/33352227850/ |date=August 12, 1956 |access-date=January 22, 2021}} Yards along the North Main Line in Pampanga became the storage location of these locomotives until they were all scrapped in the 1960s and onwards.{{Cite AV media |first=Dave |last=Sherron |title=Nippon Sharyo No. 302 |url=https://scontent.fmnl4-2.fna.fbcdn.net/v/t1.6435-9/32293373_2053762491539467_2158321727388516352_n.jpg |date=1963 |access-date=May 23, 2021}}

By 1964, the Manila Railroad was reorganized and renamed into the present Philippine National Railways. The renaming took inspiration from the Japanese National Railways. The early days of the PNR was also claimed to be the agency's golden years. While operations were smaller in scale to its southern counterpart, the North Main Line was still a popular means of travel leading out of Metro Manila. The line sought an estimated daily ridership of 3,000 passengers.

The 1970s were the beginning of the decline of operations on the North Main Line. The Cagayan Valley extension was never fully realized and PNR trains only terminated at San Jose, Nueva Ecija. The tunnel boring machines were then sold-off as debt payment for the project, and track work has been reverted into roads. A later investigation found that the Marcos government transferred the funds to the construction of the Maharlika Highway. The 1980s started the closure of the line due to decreasing ridership. A bridge collapse in 1984 ordered the closure of the services to the Ilocos Region. The line was then reduced to Caloocan in 1988, leaving the South Main Line the only operational intercity line at that point. There was a brief return of a commuter rail service to Malolos as part of the Metrotren program between 1990 and 1997.{{Cite news |title=Metrotren Inaugural |url=https://flickr.com/photos/79691913@N05/9719461423/ |work=Manila Chronicle |date=May 11, 1990 |accessdate=May 6, 2021}}

Since then, the Ramos administration took advantage of the recently closed North Main Line to revitalize plans to electrify the commuter rail service in Metro Manila.

Another railway project was also proposed during the late 1990s as part of the Philippines 2000 program under President Ramos. In 1995, the Manila–Rizal–Laguna–Quezon Growth Corridor (MARILAQUE) was proposed and the MARILAQUE Commission was established for the development of the area. They were tasked by the national government to implement the Silangan Railway Express 2000 project. The {{Convert|95|km|abbr=on}} line would have connected the northern half of Metro Manila to Rizal similar to the pre-war Antipolo and Marikina lines. It would then be extended eastward towards eastern Rizal province and northern Quezon, both more rural than the areas once plied by the two aforementioned lines.{{cite act |type=Administrative Order No. 214, s. 1995 |index= |date=August 30, 1995 |legislature=Office of the President (Philippines) |title=CREATING AN EXECUTIVE COMMITTEE TO OVERSEE THE BOT/BOO IMPLEMENTATION OF THE PROPOSED SILANGAN EXPRESS 2000 RAILWAY SYSTEM CONNECTING METRO-MANILA AND QUEZON PROVINCE |url=https://www.officialgazette.gov.ph/1995/08/30/administrative-order-no-214-s-1995/ |language=en |access-date=May 28, 2021}} While plans continued under the term of President Joseph Estrada with the Japan International Cooperation Agency (JICA) by as late as 1999, it never materialized and was not considered to be built by future administrations.{{Cite report |title=TECHNICAL REPORT NO. 3: URBAN / TRANSPORTATION DEVELOPMENT CONDITION IN ADJOINING AREAS |url=https://openjicareport.jica.go.jp/pdf/11580495_03.pdf |work=METRO MANILA URBAN TRANSPORTATION INTEGRATION STUDY |publisher=Japan International Cooperation Agency |date=1999 |access-date=May 28, 2021}}

There were no services on the North Main Line during much of the 2000s, although the line was still used for trains heading to PNR's maintenance facility in Caloocan. Trial service on the North Main Line were planned later on. Between 2009 and 2010, PNR stations were renovated including a number of stations on the North Main Line. Some second-hand 12 series coaches were also acquired from the East Japan Railway Company as the NR class. These coaches were later reassigned to the South Main Line.{{Cite journal|last1=Peadon|first1=Brad|title=April 2020|volume=3|journal=Philippine National Railways Rolling Stock Update|publisher=Philippine Railways Historical Society}} Despite these initial plans not continuing as planned, the line was eventually reactivated.

{{Main|List of Philippine National Railways stations#North Main Line (Northrail)}}

The North Main Line currently only has stations within northern Metro Manila, though it previously had stations in Bulacan, Pampanga, Tarlac, Pangasinan and La Union. Branch lines also led to Nueva Ecija, while tracks and track bed were already placed in Isabela and Cagayan prior to the Cagayan Valley extension project's cancellation in the 1970s.

Only two commuter rail services run on the North Main Line, both of which only operate within Metro Manila. This is unlike its counterpart to the south that would have some trains lead to neighboring Laguna province during rush hour.

There are only two services that run on the North Main Line as of 2019:

• The Metro North Commuter service runs between Tutuban station in Manila and Governor Pascual station in Malabon. This service does not pass through any stations on the South Main Line due to the wye junction in Tondo, Manila.
• The Shuttle Service runs between Governor Pascual and {{stn|Bicutan}}, Parañaque on the South Main Line. Unlike the Metro North Commuter, it skips Tutuban via the Tondo wye and would go towards the direction of {{stn|Blumentritt||PNR}} for southbound trains or {{stn|Solis}} for northbound trains.

The North Main Line hosted both intercity and commuter trains like its southern counterpart. While its intercity services have been discontinued since 1988 and much of the right of way has been converted to roads, its commuter service was reconstructed and reopened in 2018. However, not all of its historic commuter operations are in active service and these are set to be replaced within the 2020s either by rapid transit or the NSCR.

There were several commuter rail services leading in and out of Manila on the North Main Line during its history. Some of the lines were eventually closed, and their reconstruction were later deemed unnecessary to restore because of existing rapid transit infrastructure from other systems.

• The first known commuter rail branch on the North Main Line was the Antipolo line. Inaugurated in 1908, it connected Antipolo, Manila province to downtown Manila via Santa Mesa. Services on this line were hauled by specialized tank locomotives due to its steep gradients such as the Manila Railroad 160 class Kitson–Meyer locomotives. This was however closed in 1917 after a Supreme Court of the Philippines ruling that ordered the closure of the line.{{Cite web |title=EN BANC - G.R.

The extension opened on July 5, 2021, replacing the old Antipolo line.
• The Marikina branch was finished earlier than the Antipolo line in 1906 to Marikina, but was closed much later. The line branched off the Antipolo line in Marikina and led to Montalban. After the Antipolo line was closed in 1917, the line was closed in 1936 at the same time with the Naic line to Cavite.{{Cite web |title=Railways of old in Manila and Rizal |url=https://d0ctrine.com/2011/11/08/railways-of-old-in-manila-and-rizal/ |website=d0ctrine.com |date=November 8, 2011 |access-date=May 22, 2021}} The section up to Marikina is also set to be replaced by the LRT Line 2 eastward extension.
• The Guadalupe line was the {{Convert|13|km|abbr=on}} reconstruction of the old Antipolo line in the 1970s from Santa Mesa, Manila to Mandaluyong. It terminated at Guadalupe station, but it was located on the other side of the Pasig River as its namesake district in Makati.{{Cite AV media |title=1974 0911 PNR Schedule |url=https://www.flickr.com/photos/79691913@N05/7203660366 |work=Times Journal |date=September 11, 1976 |access-date=May 22, 2021}} The line was closed in 1983 after only 9 years of operations, and the rail bridge that carried the line was destroyed in 1991. The area in which the Guadalupe line operated has now been covered by the LRT Line 2 and the MRT Line 3.
• There was also a once-a-day service between {{stn|Tutuban}} and {{stn|San Fernando||Pampanga}}. It was opened on January 21, 1968. The service took around 2 hours in 1976, in which it was extended to Angeles.{{Cite AV media |first=Gorio |last=Belen |title=To Fulfill Another Commitment |url=https://www.flickr.com/photos/goriob3/6816716926/ |work=Times Journal |date=January 20, 1968 |access-date=May 22, 2021}} The service was closed in 1988 with the closure of the entire North Main Line outside of Metro Manila. This service in particular shall be superseded by the NSCR North, which will extend services further to New Clark City in Capas, Tarlac.
• The last commuter service on the line out of Metro Manila was the Metrotren Tutuban–Malolos service. Inaugurated not long after the closure of the commuter service to Pampanga in 1990, the service led to Malolos, Bulacan. However, it was short-lived and was closed amidst the 1997 Asian financial crisis. This service shall also be superseded by the NSCR North with {{stn|Malolos}} as the terminus of Phase 1.

The North Main Line was first opened when the Manila–Dagupan Railway was opened in 1892. At its height between the 1950s and 1960s, the line went from Tutuban to Dagupan and also served until San Fernando, La Union. The line also boasted several rail yards. It also had branch lines to various areas in Central Luzon. However, its services severely deteriorated in the 1980s. All regular operations outside Metro Manila first ended in 1988,{{Cite web|title=Manila North Line|url=http://asia.stationspast.net/philippines/manilla-north-line/|website=When There Were Stations: Asia|date=April 13, 2011 |access-date=March 8, 2020}} and the line was closed in 1997.

The Amianan Express was a night train service that opened in 1974. It left Manila by 11 PM and arrived in San Fernando by 4:30 AM the next day. It was serviced by then-new PNR 900 class diesel-electric locomotives and five coaches capable of seating 912 people. After ending in San Fernando station, commuters would take the bus to Ilocos Norte and Sur, and Benguet. Later, it was expanded into two services, the Amianan Day Express and the Amianan Night Express. The Amianan Night Express ran faster than its day counterpart, the Amianan Day Express, making the {{convert|260|km|mi|abbr=on}} run to San Fernando, La Union in five hours.{{cite AV media |title=1974 0215 PNR Amianan Express Trains |url=https://www.flickr.com/photos/fairlane/5542113081 |website=Flickr |date=February 15, 1974 |access-date=March 8, 2020}}

The difficulty of terrain to build new train lines prevented both MRR and PNR to have direct train services to Baguio City, then a small hill station in the Cordillera Region. There were already plans for a rail line to the town, but was ultimately cancelled in 1917 due to lack of funding.

• The first train service was the Baguio Special ({{langx|es|Manila a Baguio Especial||Manila–Baguio Special}}{{Cite AV media|title=Swiss luxury watch brand Omega featuring Manila Railroad's Baguio Special train in a 1915 advertisement.|url=https://www.facebook.com/PTERCOfficial/photos/a.1814507465464972/2981444922104548/|publisher=Omega SA, via Philipine Train Enthusiasts and Railfans Club|date=1915|access-date=November 7, 2021}}). It was inaugurated in 1911 and was the country's first flagship service. The train initially stopped in Pangasinan until the line was later extended to Damortis station in Santo Tomas, La Union.{{Cite AV media |title=Baguio Special at Manila Station c. 1911 |url=https://flickr.com/photos/ssave/31892788040/ |date=September 1912 |access-date=May 26, 2021}} From here, limousines would take travelers to Baguio. This service was extremely popular that Damortis went through an overhaul in 1938 to support the demand of travelers.{{Cite report |title=Report of the General Manager for the Year Ended December 31, 1938 |work=Reports of the General Manager |publisher=Manila Railroad Company |date=March 17, 1939}}
• In 1922, a night service was added. At least one car was ordered from the American Car and Foundry Company to serve the Baguio Night Special. Both services ended in 1941.{{Cite report |title=Report of the General Manager for the Year Ended December 31, 1922 |work=Reports of the General Manager |publisher=Manila Railroad Company |date=March 25, 1923}}
• A second service was inaugurated by the MRR by around 1955. Passengers would ride the train from Tutuban to Damortis station in Santo Tomas, La Union, then will ride a limousine service of Chevrolet Bel Airs to Pines Hotel in Baguio. It costed ₱45 (equivalent to $217 in 2020 US Dollars) for this package.{{cite web|title=1955 0916 MRR Package Tour ad|url=https://www.flickr.com/photos/goriob1/5000098279/in/pool-1395212@N21/|website=Flickr|date=September 16, 2010|access-date=March 11, 2020}}
• The third and last service was opened during the PNR era with a bus service leading to Baguio, with buses provided by Hino Motors. This service operated until all provincial services on the North Main Line were suspended by late 1984, when all trains to the Ilocos Region were suspended.{{cite web|title=1984 PNR MOTOR SERVICES|url=https://www.flickr.com/photos/intervene/4817155739/in/pool-1395212@N21/|website=Flickr|date=June 22, 1984|access-date=March 11, 2020}}

The Dagupan Express opened on February 10, 1979. It was serviced by the MCBP class diesel multiple units, the intercity version of the MC-300 multiple units of 1968. Like the Amianan Express, the Dagupan Express also ended in 1984 after all North Main Line services terminated in Tarlac.{{cite web|title=1974 0215 PNR Amianan Express Trains|url=https://www.flickr.com/photos/goriob3/6689305725|website=Flickr|date=January 12, 2012|access-date=March 8, 2020}}

The Ilocos Express was inaugurated on March 15, 1930. The services includes a dining car with catering provided by the Manila Hotel. Another variant of the service was the Baguio-Ilocos Express. Following the modernization program of the Manila Railway Company in 1955, the Ilocos Express featured a 7A class "De Luxe" coach until 1979, when the lack of operable air-conditioned coaches caused a switch to a "Tourist"-class coach. The company also operated the Paniqui Express in the 1930s, but that was eclipsed by the Ilocos Express. There were two accidents involving the service, one in 1939 and another in 1959.{{cite web|title=Official Week in Review: April 12 – April 18, 1959|url=http://www.officialgazette.gov.ph/1959/04/20/official-week-in-review-april-12-april-18-1959/|website=Official Gazette of the Republic of the Philippines|date=April 20, 1959 |access-date=March 11, 2020}}

It was also known as the Ilocos Special on Spanish language promotional material. Such services were intended to connect Tutuban and Manila within 6 hours using newly-refurbished locomotives that burn fuel oil instead of coal.{{Cite AV media|title=1930 MRR Ilocos Express Special Ad|url=https://www.facebook.com/PTERCOfficial/photos/a.1814507465464972/3263882730527431/|date=March 15, 1930|access-date=November 14, 2022}}

Due to the North Main Line only running a few kilometers north to Malabon, the line runs relatively few trains. The line currently uses PNR Hyundai Rotem DMUs, 203 series and PNR 8000 class trainsets. Ex-JNR rolling stock such as KiHa 35 and KiHa 52 have been out of service for the line.

The North Long Haul project shall revive the intercity section of the North Main Line north of New Clark City station in Capas. It shall also expand into regions that were not served by railways. The line is set to be connected to the South Main Line through the NSCR, the SCRP and the North Dry Port projects.

A majority of the project's main lines have been proposed since 1875, long before intercity services were opened in 1892. The Cagayan Valley Extension, predecessor to the North Long Haul East, initially had some of its right of way built in the 1950s and 1960s. However, construction was cancelled after 1966 and the equipment used was later sold. Contemporary efforts to reviving the North Main Line were first announced in 2017 during a DOTr's presentation to the South Korean Ministry of Foreign Affairs.{{Cite web |title=RAILWAY PROJECT ROADSHOW: MINDANAO RAILWAY (TAGUM-DAVAO-DIGOS SEGMENT) |url=https://overseas.mofa.go.kr/ph-ko/brd/m_3647/down.do?brd_id=3720&seq=1207121&data_tp=A&file_seq=1 |publisher=Department of Transportation (Philippines), presented to the Ministry of Foreign Affairs (South Korea) |date=December 13, 2017 |access-date=May 24, 2021}} It is expected that the system will be electrified with 1.5 kV DC electrification, being future extensions of the NSCR North and the SCRP. The upgrades shall happen once enough traffic has been reached to justify their implementation.

The system consists of two lines:

• The North Long Haul West is a reconstruction of the old North Main Line between New Clark City and La Union, with extensions to Laoag, the supposed final terminus of the Manila-Dagupan Railway. The line was expected to be around {{Convert|159|km|abbr=on}} long, shortened from the former length of {{Convert|175|km|abbr=on}} due to changes in design. In 2023, the line's length was extended up to Laoag, Ilocos Norte, adding a further {{Convert|183|km|abbr=on}} from its initial terminus at San Fernando, La Union, bringing the total length to {{Convert|419|km|abbr=on}}.{{Cite web |title=Invitation for Negotiated Procurement for Project Preparation Services for the North Long Haul (NCR-Ilocos Norte and Cagayan) Inter-Regional Railway Project|url=https://ppp.gov.ph/wp-content/uploads/2023/12/PDMF_NLH-Invitation-to-Negotiate-20231227.pdf |work=Republic of the Philippines Public-Private Partnership Center |date=December 27, 2023 |access-date=June 13, 2024 |language=en}}
• The North Long Haul East aims to revive the failed Cagayan Valley Extension project that was cancelled in the late 1960s. Branching off the old main line at Tarlac City, the line will continue towards the direction of San Jose, Nueva Ecija from which the {{Convert|10|km|abbr=on}} Caraballo Tunnel will be built. After the tunnel, the line continues northward to Isabela and Cagayan until it terminates at Tuguegarao. The line is expected to be around {{Convert|434|km|abbr=on}} long.
