According to Proceso, Mexico City's head of government, Clara Brugada, announced that the full renovation of Metro Line 3, part of the Sistema de Transporte Colectivo (STC, the city's collective transport system), will require an estimated investment of more than 40 billion pesos, over 18 times the amount spent on the intervention of Line 2. Brugada said the project will be financed through a co-investment scheme without raising the current five-peso fare, made during the presentation of the project for the line connecting Indios Verdes and Universidad on July 14.
Brugada noted that each metro ticket costs around 13 pesos to provide, while it is sold to the public at five pesos, with the government absorbing the difference as a subsidy. She stated the administration would maintain the current fare. Per Proceso, the intervention of Line 2 required an investment of 2,200 million pesos, of which 1.418 billion pesos went to major maintenance of trains, tracks, electrical systems and facilities, and 782 million pesos to the full renovation of 19 stations, meaning the Line 3 project represents an investment more than 18 times larger than that spent on Line 2.
The intervention on Line 3 will cover the acquisition of 45 new trains, full renovation of the track system, modernization of electrical, electromechanical and signaling systems, and rehabilitation of the line's 21 stations. Works will follow a model designed to reduce service disruptions, concentrating heavy activity in night hours, weekends and staged phases. Brugada stated that no station on Line 3 will close this year and that service will not be interrupted in 2026.
Metro director general Adrián Rubalcava presented the completed rehabilitation of Universidad station, where coverings, roofing, ceilings, marble flooring, LED lighting, electronic access controls and signage were renewed, alongside a commercial reorganization and an artistic intervention. Finance secretary Juan Pablo de Botton said the invitation to bid was published on June 19, with the technical guidelines released in the Gaceta Oficial de la Ciudad de México (the city's official gazette) on July 14, opening the process for submission and evaluation of proposals under the co-investment scheme provided for under local legislation.
