Siemens and Stadler Consortium to Deliver Fully Automated Trains for Copenhagen S-Bane
2/7/2026, 8:26:31 PM
Overview of the Project
Siemens Mobility, in partnership with Stadler, has been awarded a contract to supply and maintain 226 new S-trains for the Copenhagen S-Bane network. This initiative aims to establish the world's largest open railway system featuring fully automated train operations. The project is expected to significantly enhance service frequency and capacity, with trains running as frequently as every 1.5 minutes during peak hours in central Copenhagen.
Key Features of the New S-Bane Trains
The new S-Bane trains will incorporate innovative design elements while maintaining the familiar aesthetic of the existing DSB trains. Each 56-meter-long train will accommodate 120 seated passengers, 36 folding seats, and approximately 300 standing places. The design includes large windows for improved visibility, barrier-free access, and flexible multi-purpose areas for bicycles and wheelchairs. Enhanced passenger information systems and air conditioning are also part of the new features, aiming to provide a more comfortable travel experience.
Technological Innovations
A significant advancement in the new trains is the Air-free Brake System developed by Siemens Mobility, which reduces weight and lowers the CO2 footprint by over 50%. This system replaces traditional pneumatic brakes, contributing to more sustainable railway operations. The trains will also utilize a state-of-the-art propulsion system, ensuring optimal performance and efficiency.
Comprehensive Service Agreement
A 30-year Technical Support & Spares Supply Agreement (TSSSA+) has been established with DSB, which includes options for two additional five-year extensions. This agreement encompasses spare parts supply, maintenance support, and cybersecurity services, ensuring high reliability and availability of the S-Bane network. DSB employees will perform the maintenance work, supported by Siemens' advanced maintenance management systems.
Timeline for Implementation
The transition to fully automated operations is set to occur in phases, with the first automated services expected to begin in 2030 and full automation targeted for 2033. The upgrade will involve enhancing the entire 170-kilometer S-Bane network to the highest Grade of Automation (GoA4), utilizing the CBTC solution, Trainguard MT.
Broader Implications
The introduction of fully automated trains is anticipated to increase the capacity of the S-Bane network by up to 35%, allowing for approximately ten million additional journeys annually. This transformation is part of a broader strategy to prepare Copenhagen's public transport system for future growth, with an expected rise in passenger numbers from 111 million in 2025.
Criticism & Opposition
While the project is largely viewed positively, some critics express concerns regarding the implications of automation on employment within the transport sector. The transition to fully automated operations may lead to job reductions, prompting discussions about workforce retraining and support.
