MRT Line 2 System - The Purple Line
The Megatren, more popularly known by its generic name Line 2, is a 13.8 km mass transit line that traverses five cities in Metro Manila namely Pasig, Marikina, Quezon City, San Juan and Manila) along the major thoroughfares of Marcos Highway, Aurora Boulevard, Ramon Magsaysay Boulevard, Legarda and Recto Avenue.
The Megatren system was built at a cost of P31 billion in soft loans mainly from the Japan Bank for International Cooperation (JBIC). This is a very concessional loan, with 2 percent interest for three packages, and payable for 30 years with a 10-year grace period.
The Asia Europe MRT Consortium, led by the Marubeni Corporation, has delivered 18 new four (4) - car trains. Each train is 92.6 meters long and consists of four motorized cars. One train can seat 232 passengers. It can accommodate 1,396 more standing passengers along its spacious coaches. Compared with the previous light rail projects, LRT 2 was more difficult to build because of highly technical problems. Several international companies participated in the project, which consists of four (4) contract packages. Package 1 is the depot in Santolan, Pasig where the 18 trains are stabled, and where the employees’ quarters, and offices are based. Package 2 consists of the substructures, mainly the railway’s foundations including the columns and pilings that support the guideways. Package 3 forms the superstructure composed of the girders, or beams that support the train rails, the viaduct, and the train stations. Package 4 includes the electro-mechanical systems, the rolling stocks, the track works, including the network of cables and poles that transmit power to the trains.
A special method called the pre-casting segmental method (PSM), was used in building the viaduct or the long stretch of suspension bridges resting on the concrete towers. The method is of European technology and is widely used worldwide. In the Philippines, the Megatren Line 2 project pioneered the use of the PSM technology or the pre-casting of the girders into smaller segments so that each span connected between two columns is weighing not more than 58 tons.
The Megatren is the latest of its kind in the world today. It is a fully automatic (i.e., driver-less) system which is at par in terms of facilities and technology with those in other parts of the world. It is equipped with a CCTV system that enables the railway operator to monitor activities of passengers and employees at the stations and inside the trains. Moreover, the LRT 2 is commuter friendly and has facilities especially designed for the elderly and the differently-abled. It has Braille tactiles along the lanes and elevators which enable blind passengers to be guided on their way to the trains. The coaches are also more spacious than those of the earlier systems. These enable passengers with disabilities and those onboard wheelchairs to be able to board and alight from Megatren without any problem. Elevators are installed in the stations also for the use of the elderly and disabled passengers.
Another key feature of the Megatren is its automatic vending machines which enable the passengers to buy their tickets without queuing at the ticket booths. This allows for faster mobility of people and added convenience to commuters.
Line 2 has a total length of about 13.8 km and when fully operational, will run from Santolan, Pasig City to Recto in Manila. As of date, however, Phase 1 of the line has started operating from its Santolan Station in Pasig, heading in a northwest direction towards Katipunan, and finally, in a southwesterly direction along Aurora Boulevard, to Cubao.
It extends from Santolan, Pasig City in the east to Recto, Manila in the west with 1stations or terminals: Santolan; Katipunan, the first and only underground air-conditioned station; Anonas; Araneta Center-Cubao; Betty Go-Belmonte; J. Ruiz; Gilmore; V. Mapa; Pureza; Legarda; and Recto.
Phase One covering the stations of Santolan, Katipunan, Anonas and Araneta Center-Cubao began its operations on 5 April 2003 while Phase Two from Betty Go-Belmote to Legarda was inaugurated on 5 April 2004. Recto Station, the last station, is expected to be opened before the end of 2004.
Like its predecessors in LRT 1, all 18 trains of the Megatren are electrically-driven using a solid state propulsion technology powered by electric motors of 1,500 volts. Operated automatically by the Automatic Train Operations system, it can travel up to 80 km per hour on top speed. Travel time between Santolan and Recto will only take 30 minutes.
Recently, President Gloria Macapagal-Arroyo re-christened the Megatren as the Purple Line, noting the bright violet and canary yellow blends on the lower edge of the coaches, running from the front and all the way to the rear end. The colors and design denote the uniqueness of Philippine ethnicity.
The computerized coaches measuring 3.2 meters wide and 92.6 meters long are much bigger and faster than their Czechoslovakian counterparts of MRT 3 cruising on Edsa, and the South Korean-manufactured Adtranz trains of LRT 1.
With this size, the Purple Line trains can accommodate up to 1,628 passengers; even if there were elderly and physically disabled on board who are provided with space for their own wheelchairs and mobility tools, alongside the fiberglass reinforced plastic benches.
Every four-car train has 20 sliding doors per side to facilitate the quick and convenient boarding and alighting of passengers. Each coach is also equipped with two units of mounted air conditioners.
Each train has its own Public Address System (PAS) from which a recorded computerized announcement of each station stop emanates. The PAS could transmit music for a relaxing journey.
Designed to be commuter-friendly especially for the mobility-impaired, all elevators in all terminals of the Purple Line are with an engraved Braille, while all station concourses and platform levels are installed with path finding tactiles to guide persons with disabilities, specifically the visually-impaired.
In keeping with the fast-paced computerization and modernization of the world, the Purple Line is the first in the country to use two novel innovations in the mass rail system. These are the ticket vending machines (TVM) and the highly-sensitized Operations Control Center (OCC).
The TVMs that either accepts coins or P10, P20, P50 bills, or both, dispense single journey tickets per person. The OCC networks necessary internal and external linkages for an efficient, safe and secured service to commuters.
Aside from TV monitors, the OCC consists of ultra-modern communication gadgets and technology systems from Spain, Singapore, Germany, Japan, South Korea and France. These allow the on-the-spot recording and confirmation of all goings-on in all the stations. The Supervisory Control and Data Acquisition is responsible for the remote control management of the power supply to the depot and the entire 13.8 km stretch. The Building Management System takes care of the Katipunan underground air-conditioned station. The Centralized Paging Information System is the public address system that connects the management to their frontliners and passengers. The schematic diagram aids the OCC engineers know the problem track areas of the computerized trains which have their own black boxes similar to those of aircraft carriers.
With the goal of the national government through the Light Rail Transport Authority to provide the public with an alternative means of transportation, it is believed that Megatren or the Purple Line results in less traffic congestion on the roads, reduction in air pollution, a cleaner environment, considerable savings in travelling time, great economic benefits and a higher quality of life for commuters. The ease and convenience for large numbers of people to access the stations produce commercial, retail, and office development opportunities that contribute to faster urban renewal.

Metro-Manila, the metropolitan area of the capital of the Philippines is home to some 10 million people. A light metro system (Mass Rail Transit - MRT), which runs mainly elevated, is being developed:
LRT 1 is a fully elevated north-south route opened 1 Dec. 1984 (7 km) and June 1985 (8 km). It runs along Rizal and Taft Avenues (15 km, 18 stations). The capacity of the line was increased in 1998. The line runs on a precast concrete structure 7 m above the street, designed to withstand earthquakes. It has 1435 mm gauge and 750 V overhead power supply. Average station distance is 825 m, stations are only accessible via stairs, there are no elevators or escalators. Central, Monumento (northern terminal) and Baclaran (southern terminal) function as transfer station to buses and jeepneys. Trains operate in 2-4 car units (one unit 29.3 m long, 2.5 m wide), which have roof ventilation. A 12 km southern extension will be built by SNC-Lavalin (Canada) (Oct.2000).
MRT 3 (popularly called Metrostar) runs elevated along EDSA (Epifanio de los Santos Ave.) ring road (except Buendia station which is underground). The central section opened on 16 Dec. 1999, the southern section, which connects to LRT 1 followed on 20 July 2000. The total length is now 16.8 km, once the northern section is built the line will be 24 km.
After the first months of operation, ridership was far below expectations, mainly due to high fares compared to buses and long flights of stairs to access the elevated stations. Metrostar trains are air-conditioned.
LRT 2 (Megatren or Purple Line) runs from Manila in the west via Quezon City to Pasig in the east. The line is elevated except for Katipunan station, which is underground. Construction of this line started in 1998 and it runs along Recto Ave, Magsaysay Blvd and Aurora Blvd. The full length from Santolan to Recto Ave. is 13.8 km with 11 stations. Although called LRT, this line uses heavy rail metro vehicles. A footbridge linking the Purple Line to the Yellow Line eventually opened in March 2005.

LRT 2 may be extended further east (4km) to Masinag Junction in Antipolo, Rizal.
Manila's MRT 3 will be completed to Monumento Stn. by 2004 (?), with the stations being named (from North Ave.) Roosevelt, Balintawak, and Monumento.
LRT 1 extension south (also LRT 6, 12km) - construction starting 2005. The first phase stations are named (from Baclaran) Redemptorist, Manila International Airport (or MIA), Asia World, Ninoy Aquino, Dr. Santos, Manuyo Uno, Las Piñas, Zapote, Talaba, and Niyog. This section will be built by Canadian firm SNC Lavalin International. Further phases will take Line 1 southwards to Imus (11km) and later to Dasmariñas (11km).
MRT 4 is a 22.6km (20 stations) mostly elevated line running northeast from Doroteo José/Recto in Manila to Quirino Highway in Novaliches (Quezon City) connecting with North Ave. Stn. on line 3 and passing through España, Quezon, Commonwealth and Regalado Avenues. The project will be divided into two phases:
Phase 1: the section Old Bilibid - Batasan (15.1km) passing through España St., Quezon Blvd. and Commonwealth Ave. 14 stations: Old Bilibid, UST, Mendoza, Antipolo, Welcome Rotonda, Araneta, Roosevelt, Timog, Edsa, Quezon City Hall, Philcoa, Tandang Sora, Don Antonio and Batasan.
Phase 2: Batasan - Quirino Highway in Lagro (7.5km). 36 light rail vehicles are proposed to operate, providing a capacity of 550,000 passengers per day.
- MRT 7 is planned to run northeast from North Station on MRT 3 along Commonwealth Avenue in Quezon City up to Tala in Caloocan City, and the adjoining municipality of San Jose del Monte in Bulacan (see details here)
- MRT 8, or East Line, will traverse 48 km with several tunnel sections (7.8 km) from Pililla to Santa Cruz, Laguna. Phase 1 will run for 16.8 km on elevated double-track guideways from Santa Mesa, Manila, to Taytay, Rizal; then from Taytay to Angono, Rizal, serving to decongest Manila, Mandaluyong and Pasig, and the towns of Cainta, Taytay and Angono. It will follow the general alignment of Shaw Boulevard and Ortigas Avenue and entail construction of 14 stations.
The Philippine National Railway has begun work on converting track running through the city for use as an light rail transit corridor. The line will be electrified and would service the main train station Tutuban, connecting with LRT 1 at Blumentritt, the future MRT 4, LRT 2 (the alignment puts the station between Pureza and V. Mapa), and MRT 3 (between Boni and Guadalupe, though it is closer to Boni) and eventually to the Airport.
LRT 1: 5:00 - 21:00
MRT 2: 5:00 - 22:00 Mon-Fri, 6:00-20:00 Sat-Sun
MRT 3: 6:00 - 22:00, every 3 minutes during peak hours, every 5-7 minutes at other times.
LRT 1: 12-15 pesos per ride
LRT 2: 12-15 pesos per ride
MRT 3: 10-15 pesos per ride
In July 2003, a new system was presented which in the future will create a common network, including three urban lines and two suburban lines (PNR Northrail and Southrail), all sharing the same ticket.
