Overview

• Ferrocarriles Suburbanos says the disruptions stem from scheduled track-connection works for the AIFA branch running Sept. 20–25, with operations using double trains and altered frequencies.
• Riders reported journeys stretching to two or three hours, with some trains halted up to 40 minutes and severe crowding, especially at Buenavista.
• Passengers traveling from Cuautitlán, Tultitlán, Lechería, San Rafael, Tlalnepantla and Fortuna experienced the heaviest impacts along the corridor to Mexico City.
• Extended in-system times triggered automatic double charges under the 90‑minute rule, which the company says it will reimburse along with a complimentary long‑trip credit.
• The AIFA connection is a roughly 24‑kilometer extension projected to offer about a 39‑minute ride to the airport once completed toward late 2025.
