Overview
- The Sistema de Transporte Colectivo marked its 57th anniversary with officials reporting about 69.76 billion passengers carried since 1969, a 12-line network of 195 stations, and roughly 4.5 million daily riders.
- Transparency disclosures show 14,418 reported failures between 2025 and March 2026, with 51 convoys withdrawn for repair and some trains more than two decades old, problems concentrated on lines including 2, 3 and 8.
- Metro operational updates on September 3 reported high passenger volumes on Lines 2 and 3 that slowed train movement, and the agency implemented a rain-driven marcha de seguridad on Line A that raised intervals to about 8–10 minutes.
- The STC says it has recovered and returned 22 trains to service, completed an integral renewal of Line 2, and is planning a full modernization of Line 3 that will include new rolling stock, renewed tracks, and an automated pilot system.
- Riders face daily impacts such as longer waits, occasional evacuations and broken escalators or elevators, and officials warn that modernization will be multi‑year while short-term fixes like train recovery and targeted renewals aim to ease capacity and safety pressures.
