Santiago Metro Expands With $2.5 Billion Line 7 Project

The first Metropolis AS-22-UTO trainset for Santiago Metro was presented at Alstom’s manufacturing facility in Taubaté, Brazil. The unit is part of a 37-train order for the city’s new Line 7, a project with a total investment of USD 2.5 billion.

Each of the 37 trains is a five-car configuration, measuring 102 meters in length with a total capacity for 1,247 passengers. The car bodies are constructed from stainless steel and are equipped with air conditioning, passenger information systems, and USB-C charging ports. Two dedicated spaces for passengers with reduced mobility are included in every trainset.

Operations on the 26-kilometer Line 7 will be managed by Alstom’s Urbalis communications-based train control (CBTC) system. This technology facilitates Grade of Automation 4 (GoA4), enabling fully driverless operation. The system integrates high-resolution cameras and passenger intercoms directly with the central control center.

The Line 7 infrastructure project includes 19 stations and is scheduled to become operational in 2028. The initial delivery of rolling stock from the Taubaté plant to Chile is planned for the second half of 2026. The project is expected to generate 24,000 jobs during its construction and operational phases.

Upon completion, the new line will reduce end-to-end travel time between its terminals from 72 to 37 minutes and will serve an estimated 1.6 million residents. With planned extensions, the Metro de Santiago network is projected to reach a total length of 231.5 kilometers by 2033.
