Siemens Mobility supplies double-deck trains for Swiss commuter network

Siemens Mobility has received an order from Swiss Federal Railways (SBB) for 116 six-car Desiro DoSto double-deck trains, with an option for up to 84 additional units. The trains are scheduled for deployment on the Zurich S-Bahn network and in Western Switzerland from 2031.

High-capacity train platform for metropolitan transport
The Desiro DoSto is based on the Desiro HC platform, designed for high-capacity commuter rail applications. Each train provides approximately 540 seats, along with increased standing capacity to accommodate peak passenger volumes.

Compared to previous rolling stock, the new configuration offers around 30% more standing space and 10% more seating, supporting higher passenger throughput on heavily used lines.




Passenger accessibility and onboard systems
The trains feature low-floor entrances at all doors to facilitate barrier-free access. Multi-purpose areas support passenger flow and accommodate bicycles and other equipment.

Passenger information systems include large display screens and door-side indicators showing the correct exit side. Additional emergency communication systems enable direct contact with onboard or remote support services.

Power outlets are available throughout the train, including in seating areas and multi-purpose zones, supporting mobile device and e-bike charging.




Energy efficiency and material design
Energy consumption is reduced through efficient traction systems, integrated heat pump technology, and intelligent energy management within the vehicle control system.

The car bodies are manufactured using aluminium with reduced carbon footprint, contributing to lower lifecycle emissions of the trains.




Manufacturing and system integration
Production of the train car bodies is planned at Siemens Mobility facilities in Krefeld, while project management, testing, commissioning, and operational introduction will be carried out in Switzerland.

Maintenance activities during the warranty period will also be supported locally, ensuring integration with existing rail operations and infrastructure.

Application in regional rail networks
The trains are designed for high-frequency commuter services, where capacity, reliability, and rapid passenger exchange are critical. Integration into the Zurich S-Bahn network supports increasing demand in metropolitan transport systems.

The order strengthens the long-term collaboration between Siemens Mobility and Swiss Federal Railways (SBB), focusing on scalable, energy-efficient rolling stock for urban and regional mobility.
