Santiago, Chile’s bustling capital city, is marking an extraordinary milestone with the celebration of 50 years of Santiago Metro, the backbone of its public transport system. At the heart of this achievement is Alstom, a global leader in smart and sustainable mobility solutions. Since the metro first opened in 1975, Alstom has been a trusted partner, supplying trains, technology, and services that have shaped the metro into one of Latin America’s most advanced urban transport networks.
The Santiago Metro today serves more than 2.5 million passengers daily, a symbol of the city’s growth, efficiency, and resilience. Alstom’s role in this success is unmatched: nearly 75% of the rolling stock used across the network has been manufactured or supplied by the company. This deep partnership has created a reliable, safe, and increasingly sustainable metro system that continues to set international standards.
The Journey from the Beginning
Alstom’s connection with Santiago began with the delivery of the city’s first trains. These early contributions laid the foundation for decades of collaboration. From Lines 1, 2, 4, 4A, and 5, Alstom has been instrumental in ensuring that the metro grew with the needs of the city, connecting neighborhoods, universities, and business hubs.
Over time, the company has delivered modern rolling stock, upgraded signaling systems, and provided long-term maintenance services. By doing so, it has helped transform Santiago Metro into one of Latin America’s most efficient and reliable transportation networks, admired worldwide for its punctuality and safety.
Denis Girault, Managing Director of Alstom in Chile, summed it up: “Our goal from the beginning has been to deliver solutions that improve quality of life and guarantee safety for millions of passengers every day.”
NS-16: A Proud Local Achievement
One of the most remarkable milestones in this partnership came with the NS-16 trains, the first and only metro trains ever assembled in Chile. These trains represented more than technological progress—they marked a leap in local industry development and knowledge transfer, allowing Chile to play a direct role in shaping its own transportation future.
The NS-16 trains continue to serve Santiago with distinction, combining advanced design with energy efficiency, a benchmark for future rolling stock in Latin America. Their success has also inspired further innovation in sustainable transport solutions.
Advanced Signaling and Technology
Alstom’s expertise extends beyond rolling stock. The company has also supplied cutting-edge signaling technologies for key lines of the Santiago Metro, including Lines 1, 2, 4, and 5. These systems improve network safety, reduce delays, and ensure smooth operations, providing passengers with confidence in their daily journeys.
By continuously upgrading infrastructure and technology, Alstom has supported Santiago’s ability to handle millions of daily journeys with efficiency and reliability.
People Behind the Progress
The story of Santiago Metro is also the story of the people who built it. From pioneers like Jean-Pierre Curial, who worked on the NS74 trains in the 1970s, to local engineers and technicians today, the partnership has fostered a culture of collaboration and shared expertise.
Curial emphasized values that still guide the company: teamwork, transparency, and customer satisfaction. His legacy remains central to Alstom’s philosophy, inspiring new generations of engineers and professionals in Chile.
Looking Ahead: Line 7 and Expansion
While celebrating 50 years of history, Alstom is already focused on the future. The company is currently building 37 fully automatic trains for Santiago Metro’s upcoming Line 7, scheduled to open in 2028. This ambitious expansion will extend metro access to an additional 1.6 million people, easing congestion and providing faster, more sustainable travel.
Manufactured in Taubaté, Brazil, these trains will incorporate the latest automation and passenger comfort technologies. Their design reflects Alstom’s dedication to eco-friendly innovation, with reduced energy consumption, advanced safety systems, and high levels of efficiency.
Cristian Caimanque, Interface Manager for Line 7, highlighted the spirit of collaboration: “Metro is a demanding customer, but Alstom responds in a unique way, built on 50 years of trust and shared experience. It’s a relationship where we have grown together.”
Sustainability at the Core
For Santiago, sustainability is no longer an option but a necessity. The metro system already reduces road congestion and air pollution by encouraging the use of public transportation. With Alstom’s latest innovations, Santiago Metro is taking a further step toward green urban mobility.
Energy-efficient trains, automatic systems, and advanced signaling reduce the network’s environmental impact, aligning with Chile’s commitment to sustainable urban development. These efforts not only benefit Santiago but also serve as a model for other Latin American cities seeking to modernize their transportation systems responsibly.
A Shared Vision for the Next 50 Years
As Alstom and Santiago Metro celebrate this golden jubilee, their partnership reflects more than just technological success. It symbolizes a shared vision for the future of urban mobility, where innovation, sustainability, and passenger satisfaction come together.
Over the next decades, the company aims to expand its support for Chile’s transport infrastructure, introducing smarter technologies, embracing digital transformation, and continuing to prioritize environmental responsibility.
Through projects like Line 7 and beyond, Santiago Metro will remain at the forefront of Latin America’s public transport, with Alstom as its key partner in shaping a modern, inclusive, and sustainable urban future.
Conclusion: A Legacy of Excellence
Alstom’s 50-year collaboration with Santiago Metro is a story of growth, innovation, and shared commitment. From the first trains in the 1970s to the fully automated lines of the future, the partnership reflects Chile’s determination to build a transport system that serves its people with efficiency, safety, and care.
As Santiago Metro enters its next 50 years, Alstom will continue to play a defining role in its journey. By combining cutting-edge technology, sustainable practices, and a focus on people, Alstom is not only shaping mobility in Chile but also influencing the global conversation on the future of urban transport.
