Sistema de Transporte Colectivo, also referred to as the Mexico City Metro is a rapid transit system serving the Greater Mexico City area in the Latin American country. It is the world’s eighth busiest metro and North America’s second largest rapid transit system. The metro serves 16 boroughs and 41 neighbourhood municipalities of Greater Mexico City.
The transit system is operated by Sistema de Transporte Colectivo (STC). It stretches 225km (approximately) and includes 12 lines with 195 intermediate stations. Line 12 of the metro, also called the Gold Line, was opened in October 2012.
The average daily ridership of the metro is 3.86 million passengers. In 2010, the transit system served around 1.41 billion passengers.
Development stages of the rapid transit system
Construction of the metro system was carried out in seven stages. The first stage included the construction of Lines 1, 2 and 3. It was carried out between 1967 and 1972. Stage two of construction, carried out between 1977 and 1982, included the construction of Lines 4 and 5. This stage also included an extension to Line 3. In the third stage, Lines 6 and 7 were built between 1983 and 1985. Lines 1, 2 and 3 were also extended during this stage.
An earthquake in 1985 disturbed the progress of the project although construction resumed quickly. Stage four of the project was carried out between 1986 and 1987. It included the construction of Line 9 and extension of Lines 6 and 7.
In the fifth stage of construction, carried out between 1988 and 1994, Line A and Line 8 were constructed. Stage six included the construction of Line B between 1993 and 2000. The final stage of construction started in 2008. It included construction of Line 12, which was inaugurated in October 2012.
The metro was constructed at a total cost of $1.8bn (24.5bn Mexican pesos) of which $0.5bn (7.5bn Mexican pesos) was funded by the federal government and $0.42bn (5.7bn Mexican pesos) was collected in the form of local funds.
A consortium of ICA and Carso was contracted to carry out the civil works on Line 12 of the metro. Alstom was awarded a turnkey contract to supply its Urbalis CBTC-based ATO control systems and overhead electrification systems for the line.
