Mexico City Metro to Manufacture Its Own Spare Parts for All 12 Lines
Mexico City, August 26, 2026 – The Mexico City Collective Transportation System (STC) Metro has announced a significant step towards improving its operational efficiency by signing a new agreement with the Center for Engineering and Industrial Development (CIDESI). This collaboration will enable the Metro to manufacture its own spare parts, aiming to provide more efficient maintenance for its trains across all 12 lines.
The official announcement from the STC detailed that this agreement is designed to bolster maintenance efforts, rolling stock, and fixed installations throughout the Metro’s extensive network. The initiative seeks to prevent trains from being out of service for extended periods due to a lack of spare parts, a common issue that has previously affected service continuity.
Strategic Partnership for Enhanced Maintenance
The convenio was signed by Adrián Rubalcava Suárez, General Director of the STC, and Carlos Rubio González, General Director of CIDESI. Rubalcava emphasized that this new phase would allow for specific proposals to be developed, aiming to enhance maintenance processes and strengthen collaboration with national technological institutions.
“The General Director, @AdrianRubalcava, together with Carlos Rubio González, General Director of @CIDESIMX of the Ministry of Science, Humanities, Technology and Innovation, signed a framework collaboration agreement that reaffirms the synergy between both institutions, which has developed over 18 years, with notable contributions such as the Metrology Laboratory and the Advanced Digital Electronics Laboratory,” stated the STC Metro in its official communication.
This long-standing 18-year relationship between the two institutions has previously led to the establishment of key technological facilities, including the Metrology Laboratory and the Advanced Digital Electronics Laboratory. Carlos Rubio of CIDESI highlighted that their contributions have included test benches, automatic piloting systems, and developments for the logic and traction elements of the trains. These advancements directly impact critical areas for the maintenance of convoys and fixed installations of the Collective Transportation System.
Self-Sufficiency in Spare Parts Production
A key aspect of the agreement is the potential to manufacture components or spare parts within the STC’s own facilities. While the specific parts to be produced, the commencement date, and the required investment were not disclosed, this move is expected to significantly reduce reliance on external suppliers and expedite repair times.
Adrián Rubalcava noted that this measure aligns with the directives of Clara Brugada Molina, Head of Government of Mexico City, to ensure constant maintenance and operational readiness of the Metro system. The collaboration also facilitates federal contributions to improve the technological development areas of the STC, primarily located at the Zaragoza workshop.
Recent Fleet Rehabilitation and Future Investments
Prior to this agreement, the STC Metro had already rehabilitated 22 trains across its network, increasing the operational fleet on 12 lines and aiming to reduce waiting times between stations. These units are now in service on four lines, having received significant investment in spare parts and general maintenance to bring them back into daily operation. This increase in train availability is also intended to minimize service disruptions and ensure smoother circulation.
Looking ahead, the largest project announced to date involves an investment exceeding 40 billion pesos for the comprehensive renovation of Line 3 and the acquisition of 45 new trains. These new trains will replace the entire fleet on the Indios Verdes-Universidad route, where current units have been in service for over 40 years and have covered more than 3 million kilometers.
Clara Brugada, Head of Government, announced on July 14 that Line 3 will remain open throughout 2026, with its renovation scheduled to begin in 2027, following the completion of bidding processes and technical definitions for track work. She confirmed that Line 3 would be the third line to undergo improvements, after interventions on Lines 1 and 2, and assured that no station closures or prolonged service interruptions are anticipated for 2026, nor any fare increases.
The intervention on Line 3 will encompass all stations and will be carried out in sections, prioritizing off-peak hours such as nights and weekends, to limit user impact and avoid prolonged closures similar to the Line 1 renovation.
