Sweden's AB Transitio orders 13 additional double-decker trains from Stadler
04.08.2025
AB Transitio has ordered 13 additional KISS double-decker multiple-unit trains from Stadler to expand regional transport in Sweden. The comfortable vehicles, which have been adapted to the Nordic weather conditions, will be delivered from March 2028. They will strengthen the existing vehicle fleet in the Stockholm Mälaren region.

AB Transitio has commissioned Stadler to build 13 additional KISS double-decker multiple-unit trains. This order was set out in the form of an option in the contract signed by the Swedish rail vehicle leasing company with Stadler in 2016. The new vehicles will be used by the railway company Mälardalstrafik AB for regional transport in the Stockholm Mälaren region and will supplement the existing fleet of 53 Stadler trains. The vehicles manufactured in St. Margrethen, Switzerland, will be delivered from spring 2028.
More seats and a spacious feel
The additional four-car trains will enable more people to travel in the Stockholm Mälaren region. Trains have been tailormade for Nordic weather conditions, featuring closed engine rooms, double-walled carriage gangways, snow-clearing equipment and efficient underfloor heating. This will ensure a reliable service in extreme temperatures and heavy snowfall. Trains can reach a maximum speed of 200 km/h.
Just as the existing fleet, the trains will have a Nordic design, with carriages featuring a bright, open passenger layout and comfortable seating. Because Nordic countries have a larger loading gauge, they can be built higher and wider, giving the passenger area a generous feeling of space. The vehicles have 357 seats, some of which are adjustable, as well as individual reading lights, power sockets, work tables, WIFI and mobile phone boosters to improve reception. The new trains are very similar to the ones Stadler delivered since the contract signing in 2016, promoting smooth operation and efficient maintenance. In addition, the lightweight aluminium construction of the carriage bodies keeps energy consumption to a minimum.
Ideal train for the region
“The KISS double-decker train combines Nordic robustness with state-of-the-art comfort. This is ideal for reliable, efficient and comfortable regional transport in the Stockholm Mälaren region. We have a proven track record of effective collaboration with AB Transitio, and I am delighted that we can continue this partnership” says Ansgar Brockmeyer, Head of Marketing & Sales and Deputy Group CEO of Stadler.
”With these additional 13 vehicles we will strengthen the robustness of the Mälardalstrafik fleet and further increase synergies and standardisation in Transitios rolling stock fleet. I am happy that we will continue the strong partnership we have with Stadler in this project as well” says Magnus von Bahr, CEO of Transitio.
