Metro system intervention planned under Alistan project for the A line
The Mexico City Metro is set to undergo immediate repair works on Line A due to repeated structural failures exacerbated by rain, as highlighted by the recent collapse on July 30, 2025 [1].
The repair works, which are expected to focus on structural reinforcement and modernization, are necessary to prevent further collapses amid heavy rains. This approach mirrors previous interventions in other problematic lines, such as Line 12, where structural faults were corrected with maintenance, reinforcements, and rail replacement [2].
The urgency of these repairs is underscored by the inconvenience caused to users. Marlene Sánchez lamented the frequent suspensions of service, while Juan Uribe expressed concern about the possibility of an accident [3]. This year alone, Line A has been affected six times, including the incident that occurred on Monday, due to various reasons such as rainfall effects, power failure, or problems with the catenary [4].
The exact start date for the repair works on Line A is not provided, but given the recent collapse, it is implied that the works are imminent or already underway as of mid-2025.
The federal government is expected to play a supportive or possibly leading role in funding or oversight for these large-scale repairs and modernization efforts, which are typical of Mexico City's metro system [2].
The executive project for the intervention of Line A is not yet ready and will not be available in the next two months [5]. Some stations on Line A may have to be closed during the repair works, but the service from Pantitlán to La Paz resumed normally after the latest interruption.
Despite the upcoming repairs, the Metro line is still experiencing issues that require frequent repairs and interventions [6]. Clara Brugada, the head of government, has announced that repair works on Line A of the Metro will likely begin in January 2026 [7].

The federal government is anticipated to contribute funding or oversight for the significant structural reinforcement and modernization project on Line A, as historical interventions in Mexico City's metro system often involve such support. The inconvenience caused by these repetitive repair works and potential accidents in the transportation industry has sparked concern among users, such as Marlene Sánchez and Juan Uribe.
