Overview
- Claudia Sheinbaum rode the first supervised trip on Dec. 21, with officials reporting roughly 92% overall progress and civil works essentially finished.
- Outstanding tasks include integrating automatic signaling, commissioning a traction substation, completing three pedestrian bridges and conducting final safety tests.
- Planned operations call for 10 five‑car trains running 05:00–00:30 with 15‑minute intervals, with seven trains in service, two in reserve and one in maintenance.
- The Lechería–AIFA branch spans about 23.7 km with six intermediate stations plus the airport terminal, enabling a Buenavista–AIFA journey of about 43 minutes.
- The catenary has been energized for trials and authorities urged nearby residents to take precautions; the fare has not been announced, and some locals objected to tests starting before pedestrian bridges were in place.
