Mexico City Metro

The Mexico City Metro (Spanish: Metro de la Ciudad de México) is a rapid transit system serving Greater Mexico City, including parts of the State of Mexico. Operated by the Sistema de Transporte Colectivo (STC), it is the second-largest rapid transit system in North America after the New York City Subway and forms part of the Mexico City Integrated Mobility System.

The first line opened on 4 September 1969 with 12.7 kilometres (7.9 mi) of route and 16 stations. The system was last extended in 2015 and now comprises 12 lines, 195 stations, and just over 200 kilometres (124 mi) of route. Ten lines use rubber-tired trains, a technology adopted in part because of Mexico City's unstable soils. The system remained largely operational following the 1985 Mexico City earthquake.

Of the system's 195 stations, 44 serve two or more lines as transfer stations. Many stations are named after historical figures, places, and events in Mexican history. All lines operate daily from 5 a.m. to midnight.
