takeover of the Philippines, the Philippine Commission allowed the Manila Electric Railroad and Light Company (Meralco) to take over the properties of the Compañia de los Tranvias de Filipinas, with the first of twelve mandated electric tranvia (tram) lines operated by MERALCO opening in Manila in 1905. At the end of the first year around of track had been laid. A five-year reconstruction program was initiated in 1920, and by 1924, 170 cars serviced many parts of the city and its outskirts. Although it was an efficient system for the city's 220,000 inhabitants, by the 1930s the streetcar network had stopped expanding. Post-war (1945–1977) The system was closed during World War II. By the war's end, the tram network was damaged beyond repair amid a city that lay in ruins. It was dismantled and jeepneys became the city's primary form of transportation, plying the routes once served by the tram lines. With the return of buses and cars to the streets, traffic congestion became a problem. In 1966, the Philippine government granted a franchise to Philippine Monorail Transport Systems (PMTS) for the operation of an inner-city monorail. The monorail's feasibility was still being evaluated when the government asked the Japan International Cooperation Agency (JICA) to conduct a separate transport study. Prepared between 1971 and 1973, the JICA study proposed a series of circumferential and radial roads, an inner-city rapid transit system, a commuter railway, and an expressway with three branches. After further examination, many recommendations were adopted; however, none of them involved rapid transit and the monorail was never built. PMTS' franchise subsequently expired in 1974. Another study was performed between 1976 and 1977, this time by Freeman Fox and Associates and funded by the World Bank. It originally suggested a street-level railway, but its recommendations were revised by the newly formed Ministry of Transportation and Communications (now the DOTr). The ministry instead called for an elevated system because of the city's many intersections. However, the revisions increased the price of the project from ₱1.5 billion to ₱2 billion. A supplementary study was conducted and completed within three months. Advent of Line 1 (1977–2003) President Ferdinand Marcos created the Light Rail Transit Authority (LRTA) on July 12, 1980, by virtue of Executive Order No. 603 giving birth to what was then dubbed the "Metrorail". First Lady Imelda Marcos, then governor of Metro Manila and minister of human settlements, became its
