Tren Suburbano Lechería–AIFA Extension (Tren Felipe Ángeles)

Alignment

The extension branches off the original Buenavista–Cuautitlán line of the Tren Suburbano at Lechería in Tultitlán and runs 22.94 km northeast across Tultitlán, Tultepec, and Nextlalpan to Felipe Ángeles International Airport (AIFA) in Zumpango. It has six new stations: Cueyamil, La Loma, Teyahualco, Prados Sur, Cajiga, and Xaltocan. The airport terminal station is AIFA–Clara Krause, named after the wife of General Felipe Ángeles. The double track is electrified and includes three elevated viaducts and two rail bridges over the Gran Canal.

Trains run through from Buenavista in Mexico City, sharing the existing line as far as Lechería, for a total route of 41.68 km. Maximum speed is 130 km/h. The design travel time is 43 minutes, although trips took about 60 minutes at opening. The government projects 57,000 riders a day, with capacity for more than 80,000. The federal government describes the airport branch as the second stage of the line; the third stage is a separate AIFA–Pachuca train.

President Claudia Sheinbaum opened the Lechería–AIFA branch on April 26, 2026. Service began with 4 of the 10 trains, running every 30 minutes, with a target of every 12 minutes as more trains enter service. A promotional fare of 45 pesos applied to the full trip during the first month.

2026-04 — Government buys the Tren Suburbano and renames it

Three days before the opening, the government announced that the national infrastructure fund Fonadin would buy the privately held Tren Suburbano for MX$5.999B and operate it as a majority state-owned company. The system was renamed Tren Felipe Ángeles.

2025-02 — Army engineers take over construction

After repeated delays by the private builders, the federal government handed completion of the project to the Secretaría de la Defensa Nacional (Sedena). Sedena put the works at 80% complete, and ATTRAPI head Andrés Lajous announced a July 2025 opening, which was also missed.

2024-09 — Opening slips again

The works were 73% complete in June 2024. President Andrés Manuel López Obrador promised service in August 2024, but that date passed. The initial investment had been estimated at MX$25B, with MX$15B from the concessionaire’s owner, CAF, and the rest from the federal government.

2022-08 — Cost doubles to MX$25B

A June 2022 SICT update raised the projected cost from MX$12.48B (about US$627M) to MX$25B (about US$1.26B), or MX$35.6B (about US$1.8B) including operation and maintenance. At the time, opening was expected around September 2023, compared with SICT’s original target of the second quarter of 2023.

2022-02 — Construction begins

Construction of the branch began in February 2022. AIFA itself opened in March 2022, when the rail link was about 14% complete.
