A year later, public works secretary Alfredo Juinio announced that the system would consist of streetcars that were seen before the World War II, and they would accept bids for the project in the next few months.{{Cite news |date=October 5, 1978 |title=Streetcars for Manila |work=The Straits Times |pages=1}}

Following a review by the Ministry of Transportation and Communications, later the Department of Transportation (DOTr), the proposal was revised to an elevated railway to avoid building over the city's many intersections, while the option for an underground line was rejected due to the high water table in Manila and has a half a meter below sea level;{{Cite news |date=7 October 1980 |title=Manila to start building LRT next year |work=The Straits Times |pages=7}} 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.{{cite magazine |last=Satre |first=Gary L. |date=June 1998 |title=The Metro Manila LRT System — A Historical Perspective |url=http://www.ejrcf.or.jp/jrtr/jrtr16/pdf/f33_satre.pdf |magazine=Japan Railway & Transport Review |publisher=EJRCF |volume=16 |access-date=June 11, 2019}}{{rp|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 Meralco Transit Organization (Metro, Inc.), a sister company of Meralco. The line came to be referred to as Metrorail.{{cite web |title=LRTA History |url=http://www.lrta.gov.ph/index.php/history |archive-url=https://web.archive.org/web/20190609183503/http://www.lrta.gov.ph/index.php/history |archive-date=June 9, 2019 |access-date=April 19, 2019 |url-status=dead |publisher=Light Rail Transit Authority}} During that month, a Belgian consortium was chosen over other bids from France, Germany, Japan, and Switzerland.

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, signalling, 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.

The government-owned Construction Development Corporation of the Philippines was the project's sole contractor.{{rp|36}} Single column cast-in-place concrete piers carrying precast concrete T-girders and a concrete deck slab were used for the original line from Monumento to Baclaran.

Driven piles were originally used for 80 percent of the project, with spread footings being used for the remaining portion. However, during construction, it was determined that bored piles should be utilized in some areas to mitigate noise and avoid potential damage to nearby buildings. Additionally, the original use of stockpiled precast piles caused clutter on the streets during construction.

In 1981, an economic recession hit the country, and the government was unable to provide counterpart funds for civil works and right of way acquisition, which amounted to 60 percent of the project's total cost. This led to a delay in construction.{{cite book|url=https://books.google.com/books?id=lkH5Twa-OakC|title=Provision of Travelway Space for Urban Public Transport in Developing Countries|date=1993|publisher=UN-HABITAT|isbn=9789211312201|access-date=June 15, 2019}}{{rp|170}} Work finally resumed after the economic recession in September of that year along Taft Avenue, between Epifanio de los Santos Avenue (EDSA) and Libertad Street.{{cite web |date=July 14, 2014 |title=The LRT Line 1 System – The Green Line |url=http://www.lrta.gov.ph/line_1_system.php |url-status=dead |archive-url=https://web.archive.org/web/20140714152448/http://www.lrta.gov.ph/line_1_system.php |archive-date=July 14, 2014 |access-date=July 14, 2014 |publisher=Light Rail Transit Authority}} In order to make way for Carriedo station and a segment of tracks approaching the Pasig River, a department store and a classroom building nearby FEATI University were demolished.{{rp|36}}

The southern section known as Taft Line, which mostly traverses Taft Avenue between the Baclaran and Arroceros stations, was inaugurated on September 11, 1984, by President Ferdinand Marcos. Commercial operations along this section commenced on December 1. It was later extended when Carriedo station was opened on April 14, 1985. The line became fully operational on May 12, 1985, when the Rizal Line, the northern section traversing Rizal Avenue between Carriedo and Monumento, was opened.{{cite journal|url=https://pssc.org.ph/wp-content/pssc-archives/Philippine%20Planning%20Journal/Vol%20XVII,%20No.%201%20(Oct%201985).pdf|title=The LRT as a Component of Metro Manila's Transport Systems|journal=Philippine Planning Journal|volume=XVII|number=1|date=October 1985|publisher=School of Urban and Regional Planning, University of the Philippines|accessdate=November 16, 2024|pages=33–45}} During the first several years, two-car trains that could accommodate up to 748 passengers were utilized.

In July 2000, with the looming expiration of its contract with the LRTA, a labor strike was launched by employees of Meralco Transit Organization (METRO, Inc.). It paralyzed the operations of the line for a week. The LRTA decided not to renew its contract with METRO, Inc. that expired on July 31, 2000, and the former assumed operational responsibility.{{Cite news|last=Abadilla |first=Emmie V. |date=2000-08-01 |title=LRT operations revert to gov't, Metro contract expires |work=Manila Bulletin}}

Line 1 would eventually reach capacity by 1990 due to traffic congestion and air pollution. This led to an extensive refurbishing and structural capacity expansion program funded by Japan's official development assistance. The signing of the loan agreement in December 1994 marked the start of the project.{{cite report|author=Japan International Cooperation Agency|title=Metro Manila LRT Line 1 Capacity Expansion Project|url=https://www.jica.go.jp/english/our_work/evaluation/oda_loan/post/2005/pdf/2-16_full.pdf|access-date=December 4, 2021|author-link=Japan International Cooperation Agency|date=2004}} A consortium of Marubeni Corporation, Adtranz, and ABB was tapped in 1996 to execute the {{Philippine peso|4.1 billion}} project.{{Cite news|last=Marcelo |first=Ellen S. |title=P2.77-B LRT I contract awarded : Marubeni - ABB group wins |work=Manila Bulletin |date=1996-08-29}}{{Cite news|last=Villegas |first= Paul N. |title=LRTA, Marubeni Corp. sign P1.94-B pact to expand LRT 1 |work=Business World |date=1996-09-24}} As part of the initial phase of the expansion project, in addition to structural improvements, Hyundai Precision & Industries supplied seven four-car trains, while the original two-car trains were converted into three-car trains in 1999. In line with the introduction of four-car trains, the station platforms were also extended. The project was completed in 2002.

The implementation of the project was delayed for three years amid allegations of irregularities with the bidding conducted by the LRTA. The joint venture of Sumitomo Corporation and Itochu was awarded the contract and was given the go-ahead in March 2005, paving the way for the project to move forward.{{Cite news|title=P8.5-billion LRT-1 expansion approved |first=Sabdy |last=Araneta |url=https://www.philstar.com/headlines/2005/03/20/271031/p85-billion-lrt-1-expansion-approved |work=The Philippine Star |date=March 20, 2005 |access-date=June 26, 2024}} The second phase of the capacity expansion project was divided into two packages.

With the completion of the first phase of the MRT Line 3 in 1999, there were plans to extend Line 3 towards {{stn|Monumento}} (Phase 2) to create a seamless rail loop around Metro Manila.{{Cite news|title=MRTC gets support on Edsa MRT-3 phase 2 project|url=https://www.philstar.com/business/2003/02/24/196630/mrtc-gets-support-edsa-mrt-3-phase-2-project|website=The Philippine Star|date=February 24, 2003|access-date=February 6, 2022}} However, the extension was shelved by then-President Gloria Macapagal Arroyo in favor of a {{Convert|5.7|km|mi|sp=us|adj=on}} extension of Line 1 to a common station at North Avenue.

SNC-Lavalin then proposed a physical extension of LRT Line 1 to the province.

The line is predominantly aligned to the path of Taft Avenue (Radial Road 2) which was chosen largely due to its straight course. Later on, as Taft Avenue ends, it shifts to Rizal Avenue and Rizal Avenue Extension (Radial Road 9) then turning right on EDSA before ending at the corner of North Avenue, West Avenue, and EDSA. The south extension spans from the intersection of Quirino Avenue, Harrison Avenue, and Taft Avenue Extension, then travels down from Redemptorist Road, Roxas Boulevard, and Manila–Cavite Expressway. Afterwards, it 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 Niog station located along Aguinaldo Highway in Bacoor, Cavite.

The line links the cities of Quezon City, Caloocan, Manila, Pasay, and Parañaque, with the upcoming stations passing through the cities of Las Piñas, and Bacoor in Cavite.

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 are connected at concourse level to nearby buildings, such as shopping malls, for easier accessibility. Some trains have spaces for passengers using wheelchairs. Newer stations are barrier-free and have a separate level for the platform and concourse. The stations built for the Cavite extension also include amenities such as first aid rooms and lactation rooms, as well as platform displays.{{Cite web |last=Guiao |first=Micah Avry |date=November 20, 2024 |title=LRT-1 Cavite Extension: Your Ultimate Guide From Redemptorist-Aseana to Dr. Santos |url=https://www.spot.ph/things-to-do/weekend-guides/110516/lrt-1-cavite-extension-your-ultimate-guide-a5229-20241120-lfrm?s=g1bn0v7mrv9mkua3h74d6mkqvd |access-date=November 23, 2024 |website=Spot.ph}}

The line utilizes a variety of trains in its history and has used three different configurations, such as two-car, three-car, and four-car trainsets. The two-car trains are the original first-generation BN and ACEC trains (railway cars numbered from 1000). Most were transformed into three-car trains, although a limited number of two-car trains remain in service. The four-car trains are the more modern second-generation Hyundai Precision / Adtranz (1100), third-generation Kinki Sharyo / Nippon Sharyo (1200), and fourth-generation Construcciones y Auxiliar de Ferrocarriles (CAF) / Mitsubishi (13000).{{Cite web|publisher=Kinki Sharyo|archive-url=https://web.archive.org/web/20110717034657/http://www.kinkisharyo.co.jp/eng/e_products/sh/e_manila.htm|title=Light Rail Transit Authority, Manila Philippines, Light Rail Vehicle|url=http://www.kinkisharyo.co.jp/eng/e_products/sh/e_manila.htm|archive-date=July 17, 2011|access-date=March 8, 2010}}{{Cite web |title=MANILA LINE 1 LRV |url=http://www.caf.net/en/soluciones/proyectos/proyecto-detalle.php?p=295 |access-date=2023-12-09 |website=www.caf.net |language=en}} There are 259 railway cars grouped into 126 trains serving the line: 63 of these are first-generation, 28 second-generation, 48 third-generation, and 120 fourth-generation cars.

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, was supplied by ACEC.

In 2007, as part of a capacity expansion project, the original system was replaced with a train control system based on automatic train protection (ATP) and automatic train supervision (ATS); the fixed-block system was provided by Siemens Transportation Systems and BBR Verkehrstechnik. The ATP system monitors the speed of the trains, while the ATS system directs train operations. Prior to the 2022 upgrade, the signalling system was designed to operate at a headway of 112 seconds.{{cite report |title=MANILA LRT1 EXTENSION, OPERATIONS AND MAINTENANCE PROJECT |url=https://ppp.gov.ph/wp-content/uploads/2012/05/LRT1_CavExt_PIM_04Jun2012.pdf |website=Public-Private Partnership Center |access-date=June 7, 2020 |date=June 4, 2012 |author1=Department of Transportation and Communications|author-link1=Department of Transportation (Philippines)|author2=Light Rail Transit Authority|author-link2=Light Rail Transit Authority }}{{cite report |author=Japan International Cooperation Agency |authorlink=Japan International Cooperation Agency |author2=Oriental Consultants Co., Ltd. |author3=ALMEC Corporation |author4=Katahira & Engineers International |author5=Tonichi Engineering Consultants, Inc. |url=http://open_jicareport.jica.go.jp/pdf/12126629_01.pdf |title=LRT LINE 1 CAVITE EXTENSION PROJECT |work=STUDY ON RAILWAY STRATEGY FOR ENHANCEMENT OF RAILWAY NETWORK SYSTEM IN METRO MANILA OF THE REPUBLIC OF THE PHILIPPINES - FINAL REPORT |date=July 2013 |access-date=13 January 2022 |url-status=live |archive-url=https://web.archive.org/web/20211227073918/https://openjicareport.jica.go.jp/pdf/12126629_01.pdf |archive-date=27 December 2021 |volume=1}} Aside from the ATP and ATS systems, its subsystems include train detection through axle counters, and microprocessor-based interlocking.

The signaling system was again upgraded as part of the line's south extension. Alstom was awarded a contract in February 2016 to supply its Atlas 100 ETCS Level 1 solution for the south extension and upgrade the existing system. Between November 2021 and January 2022, the new system underwent testing and commissioning. The Light Rail Manila Corporation (LRMC) announced the completion of the upgrades on February 1, 2022.{{Cite web|title=LRMC completes upgrade of LRT-1 signalling system|url=https://lrmc.ph/2022/02/01/lrmc-completes-upgrade-of-lrt-1-signaling-system/|author=officialLRT1|website=Light Rail Manila Corporation|date=1 February 2022|access-date=2 February 2022}}
