The Ferrocarril Suburbano de la Zona Metropolitana del Valle de México (''Suburban Railway of the Valley of Mexico Metropolitan Area'') is an electric suburban rail system in Mexico City. It is also known as ''Valley of Mexico Suburban Rail System'' and colloquially referred to as ''El Tren Suburbano''. It is designed to complement the extensive Mexico City metro system, Latin America's largest and busiest urban rail network. There are projects to expand in progress and new proposals to expand the total length of the rail system to . The new projects to expand the network will include expansion into the adjacent state of Mexico.〔http://dgtfm.sct.gob.mx/index.php?id=761〕 ==Description== The initial line covers a route measuring from Mexico City's Buenavista Station north to Cuautitlán, in the State of Mexico. This initial section, which began commercial service on June 2, 2008 (after three weeks of fare-free trial operation),〔 cost US$706 million to build, with the Mexican Federal Government contributing 55% of this investment. The inaugural demonstration trip of the service from Buenavista to Lechería station and back again was made by the President of Mexico, Felipe Calderon Hinojosa, and the Governor of the State of Mexico Enrique Peña Nieto with President Calderon acting as the train's engineer. The line was built on an existing railroad right of way. However, inside Mexico City itself on the approach to Buenavista Station, a considerable amount of grade separation, including below-grade excavation and new bridges was necessary due to high density and traffic congestion. The construction elicited complaints by some Mexico City residents who objected to having their neighborhoods split by the rail line, but overall the public has supported the project. In addition to the track, the construction of Tren Suburbano also benefited from like-new electrification infrastructure already in place along most of the route, part of National Railways of Mexico (NdeM)'s Mexico City-Querétaro 25 kV 60 Hz mainline electrification completed in the 1990s but de-energized a few years later after NdeM was privatized. On August 24, 2005, CAF (Construcciones y Auxiliar de Ferrocarriles, S.A.) obtained a 30-year concession to supply rolling stock, build and operate the Tren Suburbano.〔http://www.caf.net/download.php?file=img/pdf/mexicoingles.pdf〕 The trains used on this service are electric trains built by CAF and are similar to the series 2000 trains of the Companhia Paulista de Trens Metropolitanos of São Paulo, Brazil.〔 (【引用サイトリンク】publisher=Companhia Paulista de Trens Metropolitanos )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ferrocarril Suburbano de la Zona Metropolitana del Valle de México」の詳細全文を読む スポンサード リンク
