Mexico City, Mexico

Mexico City is one of the biggest cities in the world with a population of approximately 20 million inhabitants. Since 1969 it has been developing a subway system. Now, Mexico City has 11 subway lines with a total length of 201.3 Km (125.8 miles) and 175 stations (106 in subway, 53 at grade, and 16 elevated). All the lines except Line A operate trains with rubber tyres like some lines in Paris and the subways of Montreal and Santiago, Chile. The Mexico City system, as well as those in the Mexican cities of Guadalajara and Monterrey, use symbols, as well as names, for identifying stations.

Also in Mexico City there is a light rail line connecting the subway at the Tasqueña station (line 2) across the southeast of the city to Embarcadero station (Xochimilco), a length of 18.0 km (11.2 miles), with 18 stations all of them at grade. Also currently under construction is a "bus rapid transit," a bus line with independent right of way, along the Avenida Insurgentes crossing the city from north to south. Plans are in place for the construction of a suburban railroad (commuter railroad)in Mexico City from Buenavista to Cuautitlan de Romero Rubio in the northwest suburb of the city, connecting with the subway at Buenavista station (line B) and Ferrería sation (line 6). Buenavista is the former Central passenger railroad station of Mexico City.
