Colas Rail Awarded Major Electrical and Maintenance Contract for Santiago Metro Line 9

Colas Rail Expands Chilean Footprint with Line 9 Win

Colas Rail has significantly bolstered its presence in South America after securing a major contract for the development of Line 9 of the Santiago Metro. The agreement positions the company as a primary provider of critical electrical systems and long-term maintenance for one of Chile's most ambitious urban mobility projects.

Line 9 is designed as a transformative north-south corridor intended to alleviate congestion and enhance connectivity across the Chilean capital. The project is a cornerstone of Santiago's strategy to modernize its public transport and accommodate a growing metropolitan population.

A €2.5 Billion Investment in Urban Mobility

The construction of Line 9 represents a total investment of approximately €2.5 billion. The new route will span 27 kilometers and include 19 modern stations, as well as a dedicated storage and maintenance facility.

A key objective of the expansion is seamless integration; Line 9 will connect with seven existing metro lines, creating a more resilient and interconnected network. The first operational segment of the line is slated to open in 2030, providing a vital transport link between the northern and southern districts of the city.

Critical Electrical Infrastructure and SCADA Integration

Colas Rail is tasked with the delivery of the line's "nervous system"—the electrical infrastructure required for safe and efficient train operations. The scope of work includes:

• Power Distribution: Construction of a new central electrical distribution center.
• Traction Power: Installation of eight rectifier substations to convert and supply power for train traction.
• Facility Power: Implementation of 39 lighting and power supply units across the infrastructure.
• Digital Oversight: Deployment of a Supervisory Control and Data Acquisition (SCADA) system.

The SCADA platform will allow operators to monitor power distribution and traction control from a centralized hub, ensuring rapid response to operational issues and maintaining high safety standards.

Ensuring Long-Term Reliability via 20-Year Maintenance

Beyond the initial construction phase, the contract includes a comprehensive 20-year maintenance agreement. Colas Rail will be responsible for the ongoing inspection and optimization of all installed electrical facilities. This long-term commitment is designed to minimize service disruptions and ensure the infrastructure remains efficient throughout its operational lifespan.

A Proven Track Record in Chile

This latest win is not an isolated event but a continuation of a decade-long partnership with the Santiago Metro. Colas Rail's regional expertise includes:

• Line Construction: Previous involvement in the development of Lines 3 and 6, as well as extensions to Lines 2 and 3.
• Network Management: Since 2016, the company has maintained the entire Santiago metropolitan underground network, which encompasses seven lines, 143 stations, and 149 kilometers of double track.
• National Rail Expansion: Beyond the metro, Colas Rail is working with the state-owned company EFE on the Alameda–Melipilla line, providing track and catenary systems.
