# Line 7 of the Santiago Metro reaches a key milestone

![Line 7 of the Santiago Metro reaches a key milestone](https://www.systra.com/wp-content/uploads/2026/06/the-tunnel-breakthrough.jpg)

The event was attended by the President of Chile, José Antonio Kast Rist,
underscoring the national importance of this milestone. The breakthrough came
soon after another successful tunnel connection on the same line, reinforcing
the steady progress being made across the project, and an Infrastructure project
for Line 8 awarded in 2025.

## A major contribution by the SYSTRA Subterra teams

SYSTRA Subterra has played a central role in this journey as the designer for
sections 2, 3 and 4 of Line 7. At the same time, the team is continuing to
develop the Selective Door Opening (SDO) system as phase 2 of its contract with
Metro de Santiago, helping shape not only the infrastructure itself but also the
way it will operate in the future.

> This breakthrough at Isidora Goyenecha is a clear reflection of the technical
> excellence behind this project. Delivering such complex underground
> infrastructure in a dense urban environment demonstrates the strength of
> SYSTRA Subterra’s engineering and our close collaboration with Metro de
> Santiago. We are proud to help shape the future of mobility in Santiago
> through Line 7 and beyond.
> José-Miguel Galera, CEO SYSTRA Subterra

Among the most technically demanding parts of the project is Isidora Goyenecha
Station. Building here means working in the shadow of dense urban development,
with major structures pressing close to the construction zone. Most striking of
all is the Titanium tower, a 200-metre-high landmark that rises just metres from
the station, making the engineering effort at this location especially complex
and remarkable.

## SYSTRA and the Santiago Metro: a long and successful history

Over the years, SYSTRA has become a trusted engineering partner in the
development of the Santiago Metro, contributing to its growth since the earliest
stages of the network in the 1960s. Among its most significant contributions are
the automation of Line 1, the development and extension of Lines 3 and 6, and
the design studies and construction supervision for Line 7, highlighting a
long-standing commitment to Santiago’s urban mobility.
