Overview
- On January 10–11, trains operate only between Buenavista–Morelos and Ciudad Azteca–Villa de Aragón.
- Six intermediate stations are closed: San Lázaro, Flores Magón, Romero Rubio, Oceanía, Deportivo Oceanía, and Bosque de Aragón.
- RTP buses cover Morelos–Villa de Aragón, running Saturday from 6:00 to 24:00 and Sunday from 7:00 to 24:00.
- Saturday brought long lines and waits of up to an hour as the number of support buses fell short of demand, according to local reporting and user accounts.
- Work includes casting four beams between Oceanía–Romero Rubio and Romero Rubio–Flores Magón and replacing obsolete sleepers with synthetic elements on a line that carries about 401,000 riders daily.
