Overview
- The line operated only in two segments on Jan. 10–11—Buenavista–Morelos and Ciudad Azteca–Villa de Aragón—leaving six stations closed: San Lázaro, Flores Magón, Romero Rubio, Oceanía, Deportivo Oceanía and Bosque de Aragón.
- STC said work on the elevated section included pouring four beams to stiffen the track box between Oceanía–Romero Rubio and Romero Rubio–Flores Magón and replacing obsolete sleepers with synthetic elements.
- RTP buses covered the closed stretch, but users reported overcrowding, long queues and waits of up to an hour as replacement capacity fell short of demand.
- Metro authorities say full Line B service from Ciudad Azteca to Buenavista will resume at 05:00 on Monday, with real‑time monitoring, deployment of empty trains to busy stations and reinforced staffing.
- The city’s SSC will start a ‘Regreso a clases 2026’ operation at 06:00 Monday, deploying 14,422 police with vehicle and air support to manage security and traffic near schools and transit hubs.
