Swiss train manufacturer Stadler, in a consortium with Siemens, has secured a major contract to supply 226 trains for Copenhagen's suburban railway system. The deal, valued at approximately €3 billion, also includes a 30-year maintenance agreement.

"This is the largest investment in the 90-year history of the S-Bahn."
"This order will create the world’s largest open rail system with automated train operation (ATO)."
Swiss engineering giant Stadler Rail has secured a pivotal role in a staggering €3 billion (CHF 2.75 billion) deal, cementing its status as a titan of the European railway industry. In a consortium with German heavyweight Siemens, Stadler will deliver a massive fleet of 226 trains to the Copenhagen suburban railway system. This is not merely a purchase order; it is a historic overhaul of Denmark's transport infrastructure.
The contract, one of the most lucrative in recent memory, includes a 30-year maintenance agreement and an option for an additional 100 trains, signaling a long-term dominance in the Nordic market. While the global economy grapples with uncertainty, this blockbuster deal underscores the resilience and high demand for Swiss industrial precision. The sheer scale of this investment marks the largest in the 90-year history of the Danish S-Bahn, a testament to the trust placed in this Swiss-German alliance.
Copenhagen is on the brink of a transit revolution, and Swiss technology is the driving force. This project aims to create nothing less than the world’s largest open rail system with automated train operation (ATO). By 2033, the network is expected to run fully automated, setting a new global standard for urban mobility efficiency.
Siemens Mobility Director Michael Peter describes the ambition as creating capacity for a staggering ten million additional journeys per year. This is a direct response to the urgent need for greener, faster, and more reliable public transport. The integration of state-of-the-art signaling technology will allow for a 35% increase in departures, transforming the daily commute for millions. The trains themselves are marvels of modern engineering: 56 meters long, designed to accommodate massive passenger flows while maintaining the highest safety standards.
While the exact financial split remains a closely guarded secret, the division of labor in this consortium is crystal clear. Stadler shoulders the critical responsibility of final assembly, proving once again that Swiss manufacturing is the backbone of European rail. Stadler will supply the car bodies, couplings, and the entire interior fit-out—including air conditioning and doors—ensuring the passenger experience is second to none.
In contrast, Siemens takes the lead on the electrical nervous system of the trains. The German industrial group provides the drive and braking technology, on-board power supply, and the complex vehicle control systems. Furthermore, Siemens has locked in the long-term value of the deal by securing the service and maintenance contract for the next three decades. This strategic alliance leverages the absolute strengths of both nations: German electrical prowess combined with Swiss mechanical perfection.
The numbers associated with this project are overwhelming. The new fleet will consist of four-car multiple-unit trains, each boasting 120 seats and 36 folding seats, with standing room for nearly 300 passengers. This design is a direct answer to the capacity crunch facing major metropolitan areas.
Delivery is set to commence in 2032, with a steady rollout continuing through 2040. This timeline ensures a phased but dramatic upgrade to the Danish State Railways (DSB). DSB CEO Flemming Jensen has hailed the deal as a transformative moment for the network. By replacing aging stock with these high-capacity, automated units, the consortium is not just selling trains; they are selling time and convenience to the people of Denmark. The sheer volume of 226 trains guarantees that this fleet will be the visual identity of Copenhagen's transport for generations.
For Switzerland, this deal is a powerful affirmation of its industrial relevance on the world stage. Stadler's involvement in a €3 billion international contract secures jobs and expertise within the Swiss ecosystem for years to come. Although the final assembly location is yet to be decided, the engineering DNA of these trains is undeniably Swiss.
This victory comes at a crucial time, reinforcing confidence in the Swiss export sector. It demonstrates that despite stiff global competition, Swiss quality remains a premium commodity that foreign governments are willing to pay for. As Stadler prepares to execute this monumental order, the eyes of the rail industry will be fixed on this partnership. Success in Copenhagen will likely serve as a blueprint for future mega-projects, potentially opening doors to further multi-billion euro contracts across the globe.
