SBB has signed a new contract with Siemens Mobility Switzerland for the initial supply of 116 six-car Desiro DoSto double-deck trains, as well as an option for up to 84 additional trains.
The order has been valued at approximately 2 billion Swiss Francs, with all new units set to enter service on the Zurich s-Bahn network in 2031.
Siemens Desiro SBB DoSto
Specifically designed for operation in metropolitan areas; the Desiro DoSto aims to provide ample space and comfort whilst setting new standards for sustainability. The trains offer approximately 540 seats and eight multi-purpose zones for easy boarding and alighting, as well as a higher overall capacity for highly frequented lines with roughly 30% more standing room and 10% more seating.
Low-floor entrances at all doors allow access for all passengers, and 1st class offers adjustable seats, fold-out tables and greater seat pitch for additional comfort. Power outlets are available at seats across both 1st and 2nd class, and in multi-purpose zones those with e-bikes are provided with power outlets for charging.
Siemens has also sought to improve customer information provision within the passenger compartment with more, larger screens, complemented by a light strip above doors to indicate the correct exit side.
Roland Busch, CEO of Siemens AG, said:
This contract, worth around 2 billion Swiss francs, underscores SBB’s confidence in Siemens.
Reliability, sustainability and quality of life – that is what people in Switzerland associate with the railways. And we are proud to meet these high standards for the future with our new trains and our leading technology.
The fact that key parts of the project – from project management through testing and approval runs to the start of operations – are taking place in Switzerland also demonstrates our deep ties with the country.
Characterised by low energy consumption, the trains aim to make the most of efficient traction components, an integrated heat pump, and intelligent energy management via the vehicle control system. Each car body is constructed using 100% CO2-reduced aluminium.
All new units will be delivered by Siemens Mobility, based in Wallisellen, with manufacturing planned to take place in Krefeld, Germany. Project management, testing, approval runs, commissioning and operation introduction will be carried out with local partners in Switzerland, as will maintenance work during the warranty period.
