Mexico City Metro
The Mexico City Metro (Spanish: Metro de la Ciudad de México, lit. 'Metro of the City of Mexico') is a rapid transit system that serves the metropolitan area of Mexico City, including some municipalities in the State of Mexico. Operated by the Sistema de Transporte Colectivo (STC), it is the second largest metro system in North America after the New York City Subway.
The inaugural STC Metro line was 12.7 kilometres (7.9 mi) long, serving 16 stations, and opened to the public on 4 September 1969. The system has expanded since then in a series of fits and starts. As of 2015[update], the system has 12 lines, serving 195 stations, and 226.49 kilometres (140.73 mi) of route. Ten of the lines are rubber-tired. Instead of traditional steel wheels, they use pneumatic traction, which is quieter and rides smoother in Mexico City's unstable soils. The system survived the 1985 Mexico City earthquake.
Of the STC Metro's 195 stations, 44 serve two or more lines (correspondencias or transfer stations). Many stations are named for historical figures, places, or events in Mexican history. It has 115 underground stations (the deepest of which are 35 metres [115 ft] below street level); 54 surface stations and 26 elevated stations. All lines operate from 5 a.m. to midnight.[not verified in body] At the end of 2007, the Federal District government announced the construction of the most recent STC Metro line, Line 12, which was built to run approximately 26 kilometres (16 mi) towards the southeastern part of the city, connecting with Lines 7, 3, 2 and 8. This line opened on 30 October 2012.
By the second half of the twentieth century, Mexico City had serious public transport issues, with congested main roads and highways, especially in the downtown zone, where 40 percent of the daily trips in the city were concentrated. 65 of the 91 lines of bus and electric transport served this area. With four thousand units in addition to 150,000 personal automobile peak hours, the average speed was less than walking pace.
The principal promoter of the construction of the Mexico City Metro was engineer Bernardo Quintana, who was in charge of the construction company Ingenieros Civiles y Asociados (Civil Engineers and Associates). He carried out a series of studies that resulted in a draft plan which would ultimately lead to the construction of the Mexico City Metro. This plan was shown to different authorities of Mexico City but it was not made official until 29 April 1967, when the Government Gazette ("Diario Oficial de la Federación") published the presidential decree that created a public decentralized organization, the Sistema de Transporte Colectivo, with the proposal to build, operate and run an underground rapid transit network as part of Mexico City's public transport system.
The Mexico City Metro benefited from a great amount of technical assistance made available by France. RATP's engineering branch SOFRETU played a major role in its initial planning and the design of the first lines, hence the choice of tyre/rail technology.
On 19 June 1967, at the crossroads of Chapultepec Avenue with Avenida Bucareli, the inauguration ceremony for the Mexico City Metro took place. Two years later, on 4 September 1969, an orange train made the inaugural trip between Zaragoza and Insurgentes stations, thus beginning daily operation up to today.
The first stage of construction comprised the construction, done by Grupo ICA, and inauguration of lines 1, 2 and 3. This stage involved engineers, geologists, mechanics, civil engineers, chemists, hydraulic and sanitation workers, electricians, archaeologists, and biologists; specialists in ventilation, statistics, computation, and in traffic and transit; accountants, economists, lawyers, workers and laborers. Between 1,200 and 4,000 specialists and 48,000 workers participated, building at least one kilometre (0.62 mi) of track per month, the fastest rate of construction ever for a subway.[citation needed]
