COMSA has secured three new railway projects in Mexico City worth a combined EUR 35 million (760 million pesos), further strengthening its presence in the country. The contracts focus on modernising urban transport infrastructure and advancing electromobility initiatives.

One of the projects involves the refurbishment of the Tasqueña Light Rail terminal. The work includes building a new railway platform, upgrading track and catenary electromechanical systems, and refurbishing pedestrian infrastructure. Improvements will also be made to station maintenance, accessibility through the Modal Transfer Centre, and public lighting in the surrounding area.
These upgrades are intended to improve passenger flow, enhance safety and support multimodal connections, forming part of wider urban improvements ahead of the 2026 World Cup.
Metro upgrades and maintenance
COMSA is also continuing its role in the refurbishment of Mexico City Metro Line 1, one of the capital’s most important transport corridors. Testing is under way on the completed section between Chapultepec and Observatorio.
The company’s upcoming tasks include refurbishing the Zaragoza Workshops and carrying out comprehensive maintenance across the line.
This will cover the track, electrical systems, and hydraulic and HVAC installations, reinforcing COMSA’s commitment to sustainable and electrified urban transport.
Longstanding commitment to Mexico
COMSA has been active in Mexico for more than 15 years, establishing itself as a key player in railway project delivery with its own fleet of specialised machinery and technical expertise. The company is currently participating in several tenders promoted by the Railway Transport Regulatory Agency (ARTF), including passenger rail projects on the Saltillo–Nuevo Laredo and Querétaro–Irapuato sections, underlining its support for expanding the national rail network.
The company’s work in Mexico builds on an international portfolio covering metro, tram, commuter, high-speed and Bus Rapid Transit (BRT) projects. Examples include the expansion of the Lisbon metro’s Yellow and Green lines, the BRT corridor on the DF-011 highway in Brasilia, the extension of Barcelona’s tram network, and the Kortazar viaduct on Spain’s Basque Y high-speed line between Vitoria, Bilbao and San Sebastián.
