Swiss train manufacturer Stadler, in a consortium with Siemens, has landed a major €3 billion order to supply 226 new trains for Copenhagen's suburban railway network. The deal includes a 30-year service and maintenance contract.

"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."
Stadler Rail has cemented its status as a global manufacturing titan, securing a staggering €3 billion (CHF 2.75 billion) contract in a powerhouse consortium with Siemens. This is not merely an order; it is a declaration of dominance in the European rail sector. The Swiss manufacturer, based in Bussnang, will play a pivotal role in delivering 226 state-of-the-art trains to the Danish State Railways (DSB), marking the largest investment in the 90-year history of Copenhagen's S-Bahn.
While the exact financial split remains a closely guarded secret—with a Stadler spokesperson stating firmly, "We have agreed not to disclose this"—the magnitude of the deal is undeniable. This contract secures a massive pipeline of work for the Swiss firm, which will handle the critical tasks of constructing car bodies, interior fittings, and final assembly. In an economic climate where industrial orders are fiercely contested, Stadler's ability to land a project of this volume underscores the unshakeable reputation of Swiss engineering quality on the world stage.
This project is poised to create the world’s largest open rail system with automated train operation (ATO), a technological leap that leaves competitors in the dust. Siemens Mobility Director Michael Peter confirmed the ambition, stating the network is already being modernized for "fully automated operation by 2033." This is a radical shift toward the future of urban transport, where precision and efficiency are paramount.
The division of labor within the consortium is surgical. While Stadler provides the physical excellence, Siemens—acting as the consortium leader—will supply the nervous system of the fleet. The German giant is tasked with the electrical equipment, drive and braking technology, and the sophisticated signaling required for driverless operation. Furthermore, Siemens has locked in a 30-year service and maintenance contract, ensuring that this fleet remains operational for decades. This partnership represents a formidable fusion of Swiss mechanical craftsmanship and German digital infrastructure.
The specifications of the new fleet reveal a design laser-focused on moving masses efficiently without sacrificing comfort. Each of the 56-meter-long trains is engineered to maximize throughput in Denmark's busy capital. The four-car multiple-unit trains will accommodate roughly 450 passengers, featuring 120 fixed seats, 36 folding seats, and standing room for 300 commuters. This configuration is a direct response to the urgent need for high-density transit solutions.
Stadler's responsibility extends to the entire passenger experience: air conditioning systems, doors, and interior fittings are all under their purview. The design prioritizes rapid passenger exchange, crucial for an automated system aiming for high-frequency departures. While the final manufacturing location remains undecided, the quality control will undoubtedly adhere to the rigorous standards Stadler is known for. With an option for an additional 100 trains on the table, the scale of this production effort could expand significantly, further embedding Swiss industrial capability into the daily lives of Copenhagen's citizens.
The clock is already ticking on this transformative project. The first units are scheduled to hit the tracks in 2032, initiating a rollout that will continue successively until 2040. This is a long-term commitment that will fundamentally reshape Copenhagen's transport landscape. The goal is aggressive: to increase the number of departures by a massive 35% and generate capacity for ten million additional journeys annually.
For DSB CEO Flemming Jensen, this is the "largest investment" in the network's history, a necessary evolution to keep pace with urban growth. For Switzerland, this deal is a powerful affirmation of its export economy. As Stadler prepares to execute this contract over the next decade, it reinforces the narrative that when the world needs reliable, high-capacity infrastructure, they turn to Swiss innovation. The implications are clear: Swiss industry remains a heavyweight contender capable of securing and delivering billion-euro mega-projects.
