LRT Line 1 (Metro Manila)

The line serves 20 stations along its route, of which 19 are only operational as of 2022. A twenty-first station is yet to be constructed.[14] Eight stations which are part of the south extension are also set to be constructed south of Baclaran. A previously proposed station, Malvar station in Caloocan was proposed during the construction of the northern extension located between Monumento and Balintawak stations, becoming a bargaining object during the entire extension line's construction in the jurisdiction of Caloocan. However, the planned Malvar Station was completely shelved by the Aquino administration.[15]

Three stations serve as interchanges between other lines in the metro. Doroteo Jose station is indirectly connected to the Recto station of the LRT Line 1 through a covered walkway; Blumentritt station is immediately above its PNR Metro Commuter Line counterpart; and EDSA station is connected to the Taft Avenue station via a covered walkway. No stations are connected to other rapid transit lines within the paid areas, though that is set to change when the North Triangle Common Station, which has interchanges to MRT Line 3 and MRT Line 7, opens in 2022.

In September 2020, Roosevelt station was temporarily closed to give way for the construction of the North Triangle Common Station. During this closure, the tracks extending eastward from Roosevelt station would have to be realigned in order to provide the necessary connection to the Common Station.[1]

Stations or lines in italics are either under construction, not yet operational, or have been closed.

The line operates from 4:30 a.m. PST (UTC+8) until 10:15 p.m. on weekdays, and 4:30 a.m. until 9:45 p.m on weekends and holidays.[16] It operates almost every day of the year unless otherwise announced. Special schedules are announced via the PA system in every station and also in newspapers and other mass media. During Holy Week, a public holiday in the Philippines, the rail line is closed for annual maintenance, owing to fewer commuters and traffic around the metro. Normal operation resumes after Easter Sunday.[17] During the Christmas and year-end holidays, the operating hours of the line are shortened due to the low ridership of the line during the holidays.[18]

LRTA Class 1000 being built in Bruges in 1982

The 1977 Metro Manila Transport, Land Use and Development Planning Project (MMETROPLAN), a fourteen-month study conducted by Freeman Fox and Associates and funded by the World Bank, recommended the construction of a street-level light rail line in Manila. Following a review by the Ministry of Transportation and Communications, later the Department of Transportation (DOTr), the proposal was revised to an elevated railway in order to avoid building over the city's many intersections. This raised the project's cost from ₱1.5 billion to ₱2 billion. An alignment along Rizal and Taft avenues, which spanned from Monumento, Caloocan in the north to Baclaran, Pasay in the south, was selected because it followed a relatively straight path for most of its route.[19]^: 36 On July 12, 1980, President Ferdinand Marcos created the Light Rail Transit Authority (LRTA) and assigned First Lady and Governor of Metro Manila Imelda Marcos as its chairman. While the LRTA confined its roles to policy making, fare regulation, and future planning, the line's operations were assigned to Metro, Inc., a sister company of Meralco. The line came to be referred to as Metrorail.[20]

The Belgian Government granted a ₱300 million soft and interest-free loan for the project's construction, with a repayment period of 30 years. Additional funding was later sourced from a ₱700 million loan, provided by a Belgian consortium consisting of ACEC, La Brugeoise et Nivelles, Tractionnel Engineering International, and Transurb Consult. The consortium also supplied the line's first light rail vehicles, power control, signaling, and telecommunications, as well as provided training and technical assistance. Designed as a public utility rather than a profit center, the line was expected to incur a deficit through 1993, but complete its repayments within a period of 20 years.[20]

The government-owned Construction Development Corporation of the Philippines was the project's sole contractor.[19]^: 36 In 1981, an economic recession and the government's inability to provide counterpart funds for civil works and right-of-way acquisition, which amounted to 60 percent of the project's total cost, led to a delay in construction.[21]^: 170 Work finally began in September of that year along Taft Avenue, between Epifanio de los Santos Avenue (EDSA) and Libertad Street.[22] In order to make way for Carriedo station and a segment of tracks approaching the Pasig River, a department store and a classroom building owned by FEATI University were demolished.[19]^: 36 The southern section, between the Baclaran to United Nations stations, was inaugurated on September 11, 1984, and commercial operation along this section commenced on December 1. The line became fully operational on May 12, 1985, when the northern section between Central Terminal and Monumento opened. During the first several years, two-car trains that could accommodate up to 748 passengers were utilized. This amounted to a capacity of 20,000 passengers per direction.[23]

The trains procured under the first phase of the capacity expansion in November 2006.

During the 1990s, the Line 1 reached its capacity due to traffic congestion and air pollution. In 1990, the Line 1 fell so far into disrepair due to premature wear and tear that trains headed to Central Terminal station had to slow to a crawl to avoid further damage to the support beams below as cracks reportedly began to appear.[19] The premature aging of Line 1 led to an extensive refurbishing and structural capacity expansion program with a help of Japan's official development assistance.[12]

The capacity expansion project was one of the flagship projects of the administration of President Fidel V. Ramos.[12] A loan agreement for the first phase of the capacity expansion project was signed in 1994.[12] In August 1996, a consortium of Marubeni Corporation, Adtranz, and ABB was awarded the contract and was signed the following September.[24][25] The project, undertaken at a cost of ₱4.1 billion,[26] involves the procurement of seven four-car trains that were ordered from Hyundai Precision, and the refurbishment and conversion of the original two-car trains into three-car trains in 1999. In line with the introduction of the four-car trains, the station platforms were also extended.[12] The project was completed in 2002.[12]

During the first phase of the capacity expansion, a labor strike was launched by employees of Meralco Transit Organization (METRO, Inc.) in July 2000 as their operations and maintenance contract was about to expire. It paralyzed the operations of the line for a week. The Light Rail Transit Authority decided not to renew its contract with METRO, Inc. that expired on July 31, 2000, and the former assumed operational responsibility.[27]

The trains procured under the second phase of the capacity expansion undergoing a test run in November 2006.

Another capacity expansion project was initiated in April 2000 during the administration of President Joseph Estrada due to the high demand of passengers in line with the completion of the MRT Line 3 (and eventually, LRT Line 2).[28][26] Funded through an ₱8.893-billion loan from the Japan Bank for International Cooperation,[29] the second phase of the capacity expansion project is divided into two packages. Package A involves the procurement of twelve four-car trains, upgrades to the signaling and communications equipment, and upgrades to the stations and depot. Package B, on the other hand, involves the procurement and installation of air conditioning units for the 1000 class trains, replacement of faulty air conditioning units of the 1100 class trains, renovation of 4 kilometers (2.5 miles) of railway track and railway sleepers, and procurement of equipment and spare parts used for track works. The installation of equipment for the automatic fare collection system was also included in the capacity expansion project.[28]

Balintawak station, one of the two stations constructed under the north extension project in 2016.

With the completion of the first phase of the MRT Line 3 in 1999, there were plans to extend Line 3 towards Monumento station (Phase 2) to create a seamless rail loop around Metro Manila.[30] However, the extension was shelved by then-President Gloria Macapagal Arroyo in favor of a 5.7-kilometer (3.5-mile) extension of the LRT-1 to the MRT-3 North Avenue station. The project involved the construction of three stations: Balintawak, Roosevelt, and a common station at North Avenue. However, due to disputes in the common station's location, the station would only begin construction in 2017. The extension was part of the MRT-LRT Closing the Loop project under the Arroyo administration.

In September 2008, during construction, Malvar station was proposed[31] and was met with controversies between the Caloocan local government, the general public, and the Light Rail Transit Authority.[15] The station was approved in July 2009.[32] Though it was reported that the feasibility study for the station was completed,[33] construction has yet to start.

The project was originally divided into three packages. Package A covered the construction of the viaduct while Package B covered the construction of the stations. Package C would cover the electro-mechanical systems in which includes the power supply, signaling and telecommunication systems, and railway track works. Several modifications were made in Packages A and C. Package A would be divided into two packages: Package A1, which covers the construction of the viaduct from Monumento to Balintawak, while Package A2 covered the construction of the viaduct from Balintawak to North Avenue.[33] The joint venture of First Balfour and DMCI was awarded the contract for the viaduct and stations for the north extension project.[34] Package C, on the other hand, would cover the power supply system, overhead catenary system, and station equipment. Package C was awarded to the joint venture of Miescor and GTC. Its sub-components, the signaling system, telecommunication systems, fare systems, and railway track works were contracted as four separate contracts.[33][35] The signaling contract was awarded to the joint venture of DMCI, Beta Electric, and Tewet. The communications contract, on the other hand, was awarded to the Philippine subsidiary of Alcatel-Lucent. The fare systems contract was awarded to AP Trans SA, and the track works contract was awarded to the joint venture of Daxi and Frateur-De Pourcq.[33]

The project was intended to integrate the LRT Line 1 and MRT Line 3 operations. Structure gauge tests were conducted in the extension by February 2010. The project's consultant, MetroLink Joint Venture, found that the LRT Line 1 trains can run on MRT Line 3 tracks.[36] On February 25, 2010, as part of the 24th anniversary of the People Power Revolution, President Gloria Macapagal Arroyo and Vice President Noli de Castro rode an MRT-3 train from Santolan to North Avenue before transferring to an LRT-1 train that passed along the extension until Monumento station.[37] Balintawak station opened on March 22, 2010,[38] while Roosevelt station opened seven months later, on October 22.[4]

The Tewet Group of Germany, together with its signaling partner BBR Verkehrstechnik, conducted the signaling integration of the original line and north extension. Integration works were completed in May 2011,[39] while the integration works passed inspection tests by TÜV Rheinland in June 2011.[40]

To integrate the operations of the LRT Line 1 and MRT Line 3, the then-Department of Transportation and Communications, under Secretary Jose de Jesus, launched an auction for a temporary five-year operations and maintenance contract for the two lines. The bidding was set by July 2011. Over 21 companies from around the world expressed interest to bid which included Metro Pacific Investments, Sumitomo Corporation, Siemens, DMCI Holdings, San Miguel Corporation, and others.[41] After de Jesus resigned from the DOTC,[42] his successor, Mar Roxas, halted the auction process and was later shelved.[43]

A plan to privatize the line was pursued as part of the south extension project. The bidding was set for August 2013, but failed.[44] The project was rebidded, and on September 12, 2014, the operation and maintenance of LRT Line 1 and the construction of a ₱65 billion extension project to Bacoor, Cavite was awarded to the Light Rail Manila Corporation (LRMC), a joint venture company of Metro Pacific's Metro Pacific Light Rail Corporation (MPLRC), Ayala Corporation's AC Infrastructure Holdings Corporation (AC Infra), and the Philippine Investment Alliance for Infrastructure's Macquarie Infrastructure Holdings (Philippines) PTE Ltd. (MIHPL) (with Sumitomo Corporation following in May 2020).[45][46] The consortium signed a concession agreement with the DOTr and LRTA on October 2, 2014.[47][48] LRMC contracted the operation and maintenance of the line for 20 years to RATP Dev under its subsidiary RATP Dev Transdev Asia, a joint venture between Transdev and RATP Dev on December 8, 2014.[49][50] The 32-year concession started on September 12, 2015.

A rail replacement program commenced in 2016, as a continuation of the previous rail replacement program completed by the Light Rail Transit Authority.[51] LRMC signed a contract with First Balfour for the structural restoration project of Line 1 on April 19, 2017,[52] and in November 2018, LRMC tapped First Balfour and MRail, a subsidiary of Meralco for the rehabilitation of rectifier substations.[53]

LRMC has also rehabilitated the first and second-generation trains to add more trains servicing the line.[54][55]

Most stations are composed of only one level, accessible from the street below by stairway, containing the station's concourse and platform areas separated by fare gates. Some stations tend to have a concourse level below the platforms. The single-level stations of Line 1, however, was not built with accessibility in mind, due to the lack of barrier-free facilities such as escalators and elevators. Some stations, such as Monumento and EDSA, are connected at concourse level to nearby buildings, such as shopping malls, for easier accessibility. Some trains have spaces for passengers using wheelchairs.

All stations have side platforms except for Baclaran, which has one side and one island platform. Due to the high patronage of the line, part of the platform corresponding to the front car of the train is cordoned off for the use of women, children, elderly and disabled passengers.[56]

Inside the concourse of some stations are stalls or shops where people can buy food or drinks. Stalls vary by station, and some have fast food stalls. The number of stalls also varies by station, and some stations tend to have a wide variety.

Stations such as Monumento and Baclaran are connected to or are near shopping malls and/or other large shopping areas, where commuters are offered more shopping varieties.

As a response to the COVID-19 pandemic, the system operated at a limited capacity when public transport operations resumed on June 1, 2020 after a three-month lockdown that halted the operations of public transport.[60] The use of face masks (and later, face shields) became mandatory since the resumption of operations in June 2020. The use of face shields later became no longer mandatory in public transport in November 2021, except when an area is under the two highest levels of the alert level system.[61] Social distancing measures were also implemented. Since March 1, 2022, all railway lines are operating at a full capacity due to the de-escalation of Metro Manila to the lowest of the five levels of the alert level system.[62]

In addition, talking with other passengers and answering phone calls in trains has been prohibited in the system. The policy has also been implemented in all railway lines and forms of public transport.[63]

The trains are regularly being disinfected when the train arrives at a terminus. It takes three to five minutes for a train to be disinfected.[64]

Before 2001, tokens were used for the fare system of Line 1. Subsequent upgrades in the fare collection system eventually transitioned the line from a token-based system to a ticket-based system, with full conversion to a ticket-based system achieved on September 9, 2001.[70]

Two types of magnetic tickets exist: a single-journey (one-way) ticket whose cost is dependent on the destination, and a stored-value (multiple-use) ticket for 100 pesos.

During the Arroyo administation, all magnetic tickets beard the portrait of then-President Gloria Macapagal Arroyo. The single-journey tickets had two types: a ticket that can be used for the first four stations and sold at ₱12, and another that is accepted in all stations and sold at ₱15. Single-journey tickets are valid on the day of purchase. On the other hand, stored value tickets were sold from ₱60 to ₱100. A special ticket for senior citizens and persons with disabilities were sold at ₱96. The SVTs are valid for six months after the date of first use.[71]

On July 20, 2015, a new ticketing system called Beep was introduced. The Beep is a new contactless smart card to replace the old magnetic cards. The Beep cards have two types: single-journey tickets and stored value cards, similar to the old magnetic cards. The tickets can be bought at any stations or at the ticket vending machines. The stored value cards are sold for ₱20 and can be loaded ₱12 up to the maximum limit of ₱10,000. Unlike the stored value magnetic cards which are valid for six months from the date of purchase, the Beep cards are valid for four years from the date of purchase.

On November 11, 2021, the Light Rail Manila Corporation and AF Payments, Inc. presented a QR code-based ticketing system to the Department of Transportation and the Light Rail Transit Authority. Once approved, it can serve as viable alternatives to single journey tickets and can be purchased via mobile apps. Implementation of this ticket system is slated for 2022.[72]

Adjusting passenger fares has been employed by the DOTC (predecessor of DOTr) and LRTA as a means to boost flagging ridership figures, and the issue of fares both historically and in the present continues to be a political issue.

Current fare levels were set on January 4, 2015, as a consequence of DOTr (formerly DOTC) having to increase fares for the line as per their concession agreement with the Light Rail Manila Corporation, with fare hikes delayed for several years despite inflation and rising operating costs.[73] Prior to the current fares levels, fares were set on December 15, 2003,[71][74] with the exception of a 5-peso fare increase in line of the opening of the north extension in 2010.[75] These lower fares—which are only slightly more expensive than jeepney fares—ended up being financed through large government subsidies amounting to around ₱25 per passenger,[76] and which for both the MRT and LRT reached ₱75 billion for the 10-year period between 2004 and 2014.[77] Without subsidies, the cost of a single trip is estimated at around ₱40,[76] and a ₱10 increase in fares would yield additional monthly revenues of ₱2–3 billion a month.[78]

The line maintains an at-grade depot in Baclaran, Pasay City. It serves as the center of the operations and maintenance of the line. It is connected to the mainline through a spur line. Before its expansion, the depot had a capacity of 145 light rail vehicles and an area of 6.4 hectares (16 acres).[100] It was expanded to an area of 10.6 hectares (26 acres) to accommodate 197 vehicles, with Shimizu Corporation and First Balfour implementing the project.[101] Expansion works were completed after the depot was inaugurated on February 23, 2022.[102]

A satellite depot is being constructed in Zapote as part of the line’s south extension project. When completed, the satellite depot will handle 72 light rail vehicles.[101]

New Alstom signal lights

Throughout its history, the line used different signaling systems. The line currently uses the Alstom Atlas 100 solution based on ETCS Level 1.

The original signaling system used in the LRT Line 1 was based on fixed block and relay type trackside systems. Trains had an automatic train stop system that activates if the train passes by a red signal or over-speeding. Based on a procurement plan published by the Light Rail Transit Authority, most of the signaling equipment, including track circuits, were supplied by ACEC.[7]

In 2007, as part of a capacity expansion project, the signaling system was replaced with a signaling and train control system based on automatic train protection (ATP) and automatic train supervision (ATS) using Siemens technology. The ATP system monitors the speed of the trains, while the ATS system directs train operations. Prior to the 2022 upgrade, the signaling system was designed to operate at a headway of 112 seconds.[6][103] Aside from the ATP and ATS systems, its subsystems include train detection through axle counters, and microprocessor-based interlocking.[103]

The signaling system was again upgraded as part of the line's south extension. Alstom was awarded a contract in February 2016 to supply the signaling and communications systems for the line.[9] Alstom supplied the Atlas 100 solution based on ETCS Level 1. The testing and commissioning phase of the upgraded signaling system started in November 2021 and was completed on February 1, 2022.[8]

Slab tracks (left) and tracks with ballast (right)

The tracks have two types: ballasted and slab tracks. Ballasted sections are found in the original 13.95-kilometer (8.67-mile) section from Baclaran to Monumento, while slab tracks are found in the north extension. The tracks are supported by twin-block concrete railroad ties, and have a track center distance of 3.2 meters (10 feet).[103][104]

The tracks in the original 13.95-kilometer (8.67-mile) line comprise of 50-kilogram-per-meter (100-pound-per-yard) rails designed to the EB 50T rail profile, while the tracks in the future extension line comprise of 54-kilogram-per-meter (110-pound-per-yard) rails designed to the UIC 54 rail profile.[10]

Due to the deterioration of the rail tracks in the original line, speed restrictions were implemented in 2011 except for the north extension.[84] In 2012, a contract to replace 23 kilometers (14 miles) of rails was awarded to the joint venture of Oriental and Motolite Marketing Corporation, Korail, Erin-Marty Fabricators Company, Inc., and Jorgman Construction and Development Corporation.[105] However, there were delays in the project implementation until February 2014, when the then-Department of Transportation and Communications issued a notice to proceed for the joint venture.[106] The first phase of the replacement started in 2014,[107] while the rails at Monumento station were replaced in March 2015.[108] The first phase of the rail replacement was completed in December 2015.[51] The second and final phase of replacement works commenced in August 2016 by the Light Rail Manila Corporation,[51] which contracted Joratech[109] to replace 26 kilometers (16 miles) of rails[51] and was completed in 2017.[110] This was intended to increase the operating speed from 40 kilometers per hour (25 miles per hour) to 60 kilometers per hour (37 miles per hour) and was achieved on April 5, 2021.[84]

Construction of the Cavite Extension Project viaduct along Ninoy Aquino Avenue in July 2021.

Construction of the Cavite Extension Project viaduct along C-5 Road Extension in July 2021.

The girder launcher used for the south extension construction in November 2021.

An extension of LRT Line 1 to the south, known as the South Extension Project or the Cavite Extension Project, is under construction and will serve the areas of Parañaque to Cavite.[111] The extension will span from the Quirino Avenue, Harrison Avenue, and Taft Avenue Extension intersection, then would travel down from Redemptorist Road to Coastal Road, and will traverse through the Parañaque River and will enter Ninoy Aquino Avenue until reaching and traversing the C5 Extension Road; and will once again enter Coastal Road, crossing the Las Piñas-Bacoor Boundary Bridge along the Zapote River, and traverse through the Alabang–Zapote Road and Aguinaldo Highway intersection, until reaching the Niog station located along the Molino Boulevard at Bacoor, Cavite. The extension project would add 8 stations covering 11.7 kilometers (7.3 miles) of new elevated railway sections and would be the third rail line extending outside the Metro Manila area (after the east extension of Line 2 and the construction of Line 7).[111] The project is divided in two phases - Phase 1 covers five stations from Redemptorist to Dr. Santos, while Phase 2 covers the remaining three stations from Las Piñas to Niog.[13]

The project was first approved by the National Economic and Development Authority in 2000, while the Implementing Agreement for the project was approved in 2002, to be undertaken by SNC-Lavalin as a public-private partnership project.[112][113] The proposal however was subsequently terminated in 2006.[114] In the same year, the government worked with advisers (International Finance Corporation, White & Case, Halcrow and others) to conduct an open-market invitation to tender for the extension and for a 40-year concession to run the extended line.[114][115] However, the project was shelved months before Gloria Macapagal Arroyo would end her term as President.[116]

The plans for the southern extension project were restarted as early as 2012 and was expected to begin construction in 2014 but was delayed due to right of way issues. The issues were resolved in 2016 and on May 4, 2017, the groundbreaking for the ₱64.915 billion ($1.36 billion)[117] South Extension Project was held, with the assistance of the Light Rail Manila Corporation and the Japan International Cooperation Agency.[118] The extension project also features the construction of three intermodal facilities, one satellite depot located at Zapote, and mass upgrades to the existing Baclaran depot. The project is expected to cater more than 800,000 passengers daily once completed, with the DOTr secretary Arthur Tugade projecting the early completion of the project to be within 2020.[119][120]

The line would be extended from Parañaque southwards, connecting Las Piñas and Bacoor to the Mega Manila railway network. Civil works on the extension began on May 7, 2019 after the right-of-way acquisitions were cleared.[121] The construction of the extension line will be built using a full span launching method, renowned as one of the fastest methods of construction for bridges and elevated viaducts that cuts time and total land space needed for construction. A total of 203 pi-girders were used for the construction of the extension's first phase,[122] the last of which was laid down along Redemptorist Road, Baclaran on February 7, 2022.[123] The LRMC partnered with Bouygues Construction for the civil works,[124] Alstom for the installation of the signaling and communication systems,[9] and the RATP Dev Transdev Asia[125] for the overall engineering, procurement, consultation, construction and assistance services for the project. The extension project will also serve as the first railway line to use the new construction method.

The LRT Line 1 South Extension Project will consist of the following eight stations:

• Redemptorist – Parañaque
• Manila International Airport – Parañaque
• Asia World – Parañaque
• Ninoy Aquino – Parañaque
• Dr. Santos – Parañaque
• Las Piñas – Las Piñas
• Zapote – along the boundaries of Bacoor and Las Piñas
• Niog – Bacoor

Plans were also laid out to include 2 additional stations for the extension project:

• Manuyo Uno station - Las Piñas
• Talaba station - Bacoor

As of March 2022, the project is nearly 70% complete. The extension is slated for partial operations by 2024 and full operations by 2027.[126]

Columns of the under-construction LRT-1 extension to the North Triangle Common Station in August 2021.

The original north extension until Roosevelt station will be extended to the under-construction North Triangle Common Station. The project site of the common station was disputed for years until an agreement with the stakeholders was signed in January 2017.[127] Construction of the station began on September 29, 2017[128] and is planned to open in 2022.[129]

On December 30, 2000, during the Rizal Day, an 1000 class LRV train (Car number 1037) was involved in the Rizal Day bombings at Blumentritt station. The attack on the line killed some 22 people and injured hundreds. Eight members of both Jemaah Islamiyah and the Moro Islamic Liberation Front (MILF), which include Hambal, Asia's most wanted man, and Fathur Rahman al-Ghozi, were charged with plotting and masterminding the attacks in 2003, some three years after the attacks. Three suspects were put on trial,[130][131] with al-Ghozi receiving 17 years in prison due to the illegal possession of explosives. Al-Ghozi later died in a firefight after attempting to escape from prison. Car number 1037 is decommissioned. There were plans to reconstruct it, but was ultimately scrapped along with other units deemed beyond economical repair.

• On January 3, 2008, a fire blazed at a shopping mall in Baclaran. Due to the smoke, the Baclaran station was temporarily closed. A provisional service was implemented between EDSA and Monumento (at the time, the north extension was not opened yet), with southbound trains still proceeding towards Baclaran to only serve as a turn back siding.[132] The station remained closed the following day[133] until it was reopened a few days later.
