Mexico City Metro Opens — Latin America's Largest Urban Rail Network

The Sistema de Transporte Colectivo Metro of Mexico City opened its first line on September 4, 1969 — a French-designed system with rubber-tired trains. Today the Metro has 12 lines, 195 stations, and 226 km of track, carrying 4.6 million passengers daily (pre-COVID). Mexico City Metro is Latin America's largest and the world's second-busiest by daily ridership after Tokyo. The system became politically iconic when AMLO's allies passed free metro card legislation (2023). A 2021 Metro Línea 12 overpass collapse killed 26.
