The '''Light Rail Transit Line 1''', commonly referred to as '''LRT Line 1''' or '''LRT-1''', is a [[light rapid transit]] system line in [[Metro Manila]], Philippines, operated by [[Light Rail Manila Corporation]] (LRMC) and owned by the [[Light Rail Transit Authority]] (LRTA) as part of the [[Manila Light Rail Transit System]]. Originally referred to as '''Metrorail''' and the '''Yellow Line''', LRT Line 1 was reclassified to be the '''Green Line''' in 2012. It travels in a general north–south direction from [[Dr. Santos station|Dr. Santos]] to {{stn|Monumento}}, and then east–west from Monumento to [[Roosevelt station (LRT)|Fernando Poe Jr.]] Currently, the line consists of 25 stations and runs on {{convert|26|km|mi|sp=us|abbr=off}}<ref>{{Cite web|url=https://www.urbanrail.net/as/manila/manila.htm|title = Manila |website = UrbanRail.Net |access-date=June 12, 2024}}</ref><ref>{{Cite web |last=Fuentes |first=Arthur |date=November 7, 2024 |title=LRT-1 Cavite Extension to open 5 new stations this November |url=https://abs-cbn.com/business/2024/11/7/lrt-1-cavite-extension-to-open-5-new-stations-this-november-1557 |website=ABS-CBN}}</ref><ref>{{Cite web |last=Gita-Carlos |first=Ruth Abbey |date=November 15, 2024 |title=PBBM: ‘More reliable’ transport with LRT-1 Cavite Extension Phase 1 |url=https://www.pna.gov.ph/articles/1237923 |website=Philippine News Agency}}</ref> of fully elevated route. Although it has the characteristics of [[light rail]], such as with the type of rolling stock used, it is more akin to a [[rapid transit]] system owing to its total [[grade separation]] and high passenger throughput.

First envisioned in a 1977 study conducted by [[Hyder Consulting|Freeman Fox and Associates]] which suggested a street-level railway in Manila, the government revised this recommendation to an elevated system. In 1980, President Ferdinand Marcos created the LRTA and construction of the line began the following year. With its partial opening in 1984 and completion the following year, it became the first rapid transit service in Southeast Asia.<ref>{{Cite web|last=Marasigan|first=Lorenz S.|date=2021-01-28|title=New trains for LRT-1 arrive in PHL|url=https://businessmirror.com.ph/2021/01/28/new-trains-for-lrt-1-arrive-in-phl/|access-date=2021-07-13|website=BusinessMirror|language=en-US}}</ref> LRT Line 1 would become one of the busiest among Metro Manila's three rapid transit lines, as it currently serves roughly 323,000 passengers daily.<ref name="ridership">{{cite news |title=LRT-1 Cavite Extension to open 5 stations this month |url=https://www.bworldonline.com/corporate/2024/11/08/633597/lrt-1-cavite-extension-to-open-5-stations-this-month/ |work=BusinessWorld Online |date=7 November 2024}}</ref>

The line is integrated with the public transit system in Metro Manila, and passengers also take various forms of road-based public transport, such as buses and [[jeepney]]s, to and from a station to reach their intended destination. Although the line aimed to reduce traffic congestion and travel times in Metro Manila, the transportation system has only been partially successful due to the rising number of motor vehicles and rapid urbanization.

==History==

===Planning and funding===
[[File:LRT-1 ligthrail Manila vehicle being build in Bruges.jpg|thumb|right|[[LRTA Class 1000]] being built in [[Bruges]] in 1982]]

The [https://d0ctrine.com/2014/09/05/metro-manila-transport-land-use-and-development-planning-project-mmetroplan-1977/#:~:text=The%20Metro%20Manila%20Transport,%20Land%20Use%20and%20Development%20Planning%20Project|1977 Metro Manila Transport, Land Use, and Development Planning Project (MMETROPLAN)], a fourteen-month study conducted by [[Hyder Consulting|Freeman Fox and Associates]] and funded by the [[World Bank]], recommended the construction of a street-level (at-grade) [[light rail]] line in Manila and the proposed four lines that were included in the study that would run along Rizal Avenue, Taft Avenue, [[España Boulevard]], [[Quezon Avenue]], and [[Shaw Boulevard]].<ref name="a-historical-perspective" /><ref name=":0" /> A year later, [[Secretary of Public Works and Highways|public works secretary]] [[Alfredo Juinio]] announced that the system would consist of [[Tram|streetcars]] that were seen before the [[World War II|war]], and they would accept bids for the project in the next few months.<ref>{{Cite news |date=October 5, 1978 |title=Streetcars for Manila |work=The Straits Times |pages=1}}</ref>

Following a review by the Ministry of Transportation and Communications, later the [[Department of Transportation (Philippines)|Department of Transportation]] (DOTr), the proposal was revised to an [[elevated railway]] to avoid building over the city's many intersections,<ref name="a-historical-perspective" /> 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;<ref name="ENR1983" /><ref name=":1">{{Cite news |date=7 October 1980 |title=Manila to start building LRT next year |work=The Straits Times |pages=7}}</ref> this raised the project's cost from ₱1.5&nbsp;billion to ₱2&nbsp;billion. An alignment along Rizal and Taft avenues, which spanned from [[Bonifacio Monument|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.<ref name="a-historical-perspective">{{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}}</ref>{{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.<ref name="lrta-history">{{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]]}}</ref> During that month, a Belgian [[consortium]] was chosen over other bids from France, Germany, Japan, and Switzerland.<ref name=":1" />

The [[Government of Belgium|Belgian Government]] granted a ₱300&nbsp;million [[Soft loan|soft]] and interest-free loan for the project's construction, with a repayment period of 30&nbsp;years. Additional funding was later sourced from a ₱700&nbsp;million loan, provided by a Belgian consortium consisting of [[Ateliers de Constructions Electriques de Charleroi|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&nbsp;years.<ref name="lrta-history"/>

===Construction and opening===

The government-owned [[Philippine National Construction Corporation|Construction Development Corporation of the Philippines]] was the project's sole contractor.<ref name="a-historical-perspective"/>{{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. The columns are spaced apart by {{Convert|66|to|88|ft|m|sp=us|order=flip}} rising from a cap on top of [[Deep foundation|bored or driven concrete piles]]. Four of the {{Convert|7|ft|adj=on|sp=us|order=flip}} wide girders are side by side in each span to accommodate bidirectional [[standard-gauge railway]] tracks located {{Convert|20|ft|m|sp=us|order=flip}} above the street level.<ref name="ENR1983">{{Cite news |date=January 20, 1983 |title=Light rail transit rides high; Elevated route is designed to clear snarled traffic below |page=54 |work=[[Engineering News-Record]] |publisher=[[McGraw Hill Education]] |url=https://advance.lexis.com/api/document?collection=news&id=urn:contentItem:3SJ4-GPN0-000K-J027-00000-00&context=1516831}}</ref>

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.<ref name="ENR1983" />

In 1981, an [[Early 1980s recession|economic recession]] hit the country, and the government was unable to provide counterpart funds for civil works and [[Right-of-way (transportation)|right-of-way]] acquisition, which amounted to 60&nbsp;percent of the project's total cost. This led to a delay in construction.<ref name=":0">{{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=[[United Nations Human Settlements Programme|UN-HABITAT]]|isbn=9789211312201|access-date=June 15, 2019}}</ref>{{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.<ref name="Line1">{{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}}</ref> 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.<ref name="a-historical-perspective"/>{{rp|36}}

The southern section known as Taft Line, which mostly traverses [[Taft Avenue]] between the [[Baclaran station|Baclaran]] and [[Central Terminal (LRT)|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, 1984. The line became fully operational on May 12, 1985, when the Rizal Line, the northern section traversing Rizal Avenue between Carriedo and [[Monumento station|Monumento]], was opened.<ref>{{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|page=33-45}}</ref> 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.<ref>{{Cite news|last=Abadilla |first=Emmie V. |date=2000-08-01 |title=LRT operations revert to gov't, Metro contract expires |work=Manila Bulletin}}</ref>

===Capacity expansion and facelift===
[[File:LRT Gil Puyat.jpg|thumb|left|The trains procured under the first phase of the capacity expansion in November 2006.]]
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.<ref name="ODAcep1">{{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}}</ref> A [[consortium]] of [[Marubeni Corporation]], [[Adtranz]], and [[ABB]] was tapped in 1996 to execute the {{Philippine peso|4.1 billion}} project.<ref>{{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}}</ref><ref>{{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}}</ref> As part of the initial phase of the expansion project, in addition to structural improvements, [[Hyundai Mobis|Hyundai Precision & Industries]] supplied [[LRTA 1100 class|seven four-car trains]], while the [[LRTA 1000 class|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.<ref name="ODAcep1" /> The project was completed in 2002.<ref name="ODAcep1"/>

[[File:LRT-3G Train.jpg|thumb|The trains procured under the second phase of the capacity expansion undergoing a test run in November 2006.]]

===North extension===
[[File:04100jfLRT Balintawak along EDSAfvf 03.jpg|thumb|left|[[Balintawak station]], one of the two stations constructed under the north extension project, seen in 2016]]
With the completion of the first phase of the [[MRT Line 3 (Metro Manila)|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.<ref>{{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}}</ref> 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 [[North Triangle Common Station|common station at North Avenue]]. The project involved the construction of three stations<nowiki>:</nowiki> {{stn|Balintawak}}, Roosevelt (renamed [[Roosevelt station (LRT)|Fernando Poe Jr.]]), and the [[North Triangle Common Station]]. However, due to disputes in the common station's location, the station would only begin construction in 2017, with opening slated for 2025.

Plans to build a new railway line to [[Cavite]] were pitched in the 1990s as the original [[LRT Line 6]], which would have been running between Baclaran station of LRT Line 1 and [[Bacoor]] for about {{convert|12|km|sp=us}}, but the actual route is {{convert|8|km|sp=us}} from Baclaran to Zapote, and it would have also been using a [[Heavy rail|heavy rail vehicle]] (HRV) consisting of six cars with a formation of 10 units (60 units) with a maximum speed of {{convert|60|kph|sp=us}} and a 3-minute headway, as well as the electrification would be using a [[25 kV AC railway electrification|25 kV AC]] [[overhead line]]s.

The south extension spans from the intersection of [[Elpidio Quirino Avenue|Quirino Avenue]], [[Harrison Avenue]], and [[Taft Avenue|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 [[Circumferential Road 5|C5 Extension Road]]; and will once again enter Coastal Road, crossing the Las Piñas-Bacoor Boundary Bridge along the [[Zapote River (Philippines)|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.

===Stations===
The line currently serves 25 stations along its route.<ref>{{Cite web |date=2020-08-04 |title=Train Route |url=https://lrmc.ph/our-business-featured/train-route/ |access-date=2024-11-16 |website=Light Rail Manila Corporation |language=en-US}}</ref> Following the opening of the first phase of the Cavite extension, three remaining stations, which are part of the second and third phases, are also set to start construction south of Dr. Santos by 2026. <ref>{{Cite web |last=Jose |first=Ashley Erika |date=August 12, 2024 |title=LRT-1 Cavite extension phases 2, 3 may start construction by 2026 |url=https://www.bworldonline.com/corporate/2024/08/12/613428/lrt-1-cavite-extension-phases-2-3-may-start-construction-by-2026/ |url-status=live |access-date=November 16, 2024 |website=BusinessWorld Online}}</ref> {{stn|Malvar}} station in Caloocan was previously proposed during the construction of the northern extension located between {{stn|Monumento}} and {{stn|Balintawak}}, becoming a bargaining object during the entire extension line's construction in the jurisdiction of Caloocan.

Three stations serve as connecting stations between other lines in the metro. {{stn|Doroteo Jose}} is indirectly connected to {{stn|Recto}} of the LRT Line 2 through a covered walkway; {{stn|Blumentritt}} is immediately above its [[PNR Metro Commuter Line]] [[Blumentritt station (PNR)|counterpart]]; and {{stn|EDSA|3=LRT}} is connected to the {{stn|Taft Avenue}} station via a covered walkway. No stations are connected to other rapid transit lines within the paid areas. A connection with the [[Metro Manila Subway]] in [[PITX station|PITX]] is also planned.<ref>{{Cite web |title=Infrastructure Flagship Projects (IFPs) under the Build-Better-More Program |url=https://neda.gov.ph/wp-content/uploads/2023/04/IFPs-under-the-Build-Better-More-Program.pdf |access-date=November 16, 2024}}</ref>

==Station facilities, amenities, and services==
[[Image:LRT Baclaran Station.jpg|thumb|right|{{stn|Baclaran}} station in 2008]]
All stations in Line 1 are elevated, with the exception of Zapote station.

===Station layout and accessibility===
[[File:Redemptorist Aseana station side platform center southbound F.jpg|thumb|The southbound [[platform display]] in {{stn|Redemptorist}} station.]]
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 room|first aid rooms]] and [[Lactation room|lactation rooms]], as well as [[Platform display|platform displays]].<ref>{{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}}</ref>

==Rolling stock==

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 [[LRTA 1000 class|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 ([[LRTA Class 1100|1100]]), third-generation Kinki Sharyo / Nippon Sharyo ([[LRTA Class 1200|1200]]), and fourth-generation Construcciones y Auxiliar de Ferrocarriles (CAF) / Mitsubishi ([[LRTA 13000 class|13000]]).<ref name="modernization"/><ref name=Kinki>{{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}}</ref><ref>{{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}}</ref> There are 259&nbsp;railway cars grouped into 126&nbsp;trains serving the line: 63 of these are first-generation, 28&nbsp;second-generation, 48&nbsp;third-generation, and 120 fourth-generation cars. Some of the cars, especially those from 1st generation, were decommissioned due to them being cannibalized or involved in accidents. Such as 1037, which was severely damaged in the [[Rizal Day bombings]] in 2000, it was subsequently decommissioned afterwards and eventually scrapped.<!--<ref name="LRTA Annual 2006">{{cite web |url=http://www.lrta.gov.ph/files/2006%20Annual%20Report.pdf |title=Light Rail Transit Authority Annual Report 2006 |publisher=[[Light Rail Transit Authority]].

===Signaling===
[[File:LRT-1 Alstom Atlas 100 signal lights 2024-04-07.jpg|thumb|Two-aspect signal lights ([[Alstom]]) near [[Doroteo Jose station]]]]

Throughout its history, the line used different [[Railway signaling|signaling systems]]. The line currently uses the [[Alstom]] Atlas 100 solution based on [[European Train Control System#Level 1|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 circuit]]s, was supplied by [[Ateliers de Constructions Electriques de Charleroi|ACEC]].<ref name="fixed-block-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|fixed-block]] system was provided by [[Siemens Mobility|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.<ref name="MANILA LRT1 EXTENSION, OPERATIONS AND MAINTENANCE PROJECT">{{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 }}</ref><ref name="jica2013study-1">{{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}}</ref> Aside from the ATP and ATS systems, its subsystems include [[Railway signalling#Train detection|train detection]] through [[axle counter]]s, and [[Computer-based interlocking|microprocessor-based interlocking]].<ref name="jica2013study-1" />
