Stadler Signs Westermo to Provide Comms Tech on New SBB Fleet

(29 Nov 2022, BWCS Staff)

Swiss-based train manufacturer, Stadler, has signed up Westermo to provide networking solutions for a new fleet of trains for SBB (Swiss Federal Railways). Westermo says it will supply data communication technology for hundreds of new generation single-decker FLIRT Evo multiple unit trains.

Delivery of the Westermo products will commence in 2023 and continue over a 10-year period. The first new FLIRT Evo trains, which will be used for both local and long-distance operation, are expected to enter service in 2026. This latest order builds on the strong collaboration between the two companies and follows a five-million euro deal, signed last year, for Westermo to supply on-board data networking kit for the new fleet of trains Stadler is building for the Berlin Metro.

Mark Gibbs, the Global Market Director for train networks at Westermo commented “We are delighted that Stadler has extended its collaboration with Westermo with the award of this contract to provide networking technology for its new generation of FLIRT Evo trains.  Westermo’s rail-certified solutions and expert support will ensure the data networks provide the reliability and robustness required for critical on-board systems.”

Westermo will supply a new variant of its Viper Ethernet switches to manage the on-board data networks. These EN 50155-certified switches feature innovative M12 push-pull connectors, which, the company says, simplify installation and increase network reliability. The switches are powered by Westermo’s WeOS operating software, which helps create reliable networks and offers a full range of security features to meet the growing threat of cyberattacks.

Last year, Stadler awarded Westermo the contract to supply data communications technology for a new fleet of 606 carriages for the Berlin Metro in Germany. The entire data networks on board the new trains will support mission-critical systems including the train control and management system (TCMS) as well as systems that ensure passenger comfort and safety.

The Berlin contract includes an option for an additional 894 cars and could see the datacomms kit manufacturer provide up to 8,500 of its compact Viper Ethernet switches to manage data networks on the BVG J/JK-series underground rail carriages. Deliveries commenced at the beginning of 2022 and are set to continue until around 2027.

Track-side connectivity and on-board WiFi services will be the main subjects of BWCS’s WiFi on Trains Conference in 2023 (  ).

The Full Programme for 2023 will be available in the next few weeks at the website, where you can also sign up for our Free WiFi on Trains News Service (  ).

This year’s Conference was sponsored by Westermo, Nomad Digital, GlobalReach Technology, RADWIN and BAI Communications.
