Switzerland: Aargau Verkehr Orders 5 Stadler Trains for WSB Network

Aargau Verkehr has ordered five low-floor ABe 4/8 Saphir II multiple unit trains for the use on the Wynental and Suhrentalbahn (WSB) railway in Aargau, Switzerland.

The oldest trains operating on the WSB network are due to be replaced in 2026. Aargau Verkehr has ordered five modern trains from Stadler to replace the outdated units.

This order is valued at 39.5 million CHF.

The new two-car trains will each be 40 meters long and will be in service on the WSB network from December 2025.

Severin Rangosch, CEO of Aargau Verkehr AG said:

“With the expansion of our proven Saphir fleet, an important modernisation step is imminent that will further standardise our fleet and bring even more comfort to our passengers.”

The design of the new low-floor multiple units aligns with the Saphir version that has been in use since 2019.

Alike to the previous models, they will feature bright passenger compartments with air conditioning, passenger information systems, video surveillance and a barrier-free boarding area.

The two-car trains will each be able to carry up to 253 passengers, with 85 seated. They will also offer multifunctional areas for prams, wheelchairs, luggage or bicycles.

In contrast to the Saphir I trains already in use, the new two-car trains do not have an intermediate car and are around 20 meters shorter.

Both versions can be combined during operation and used as 80 or 100-metre long compositions if needed. This will allow Aargau Verkehr to flexibly adjust to future capacity requirements.

Commissioning of the new vehicles will take place from summer 2025, leading to a timetable change in December 2025.

The first new trains will be used on the S14 route, joining existing Stadler vehicles operating on the WBS network.

André Kurmann, Sales Manager Tailor Made at Stadler said:

“We at Stadler are delighted about the order and thank Aargau Verkehr for the long-standing, successful partnership. For me, as a native of Aargau, the new order from my home canton is a matter close to my heart. Personal commitment to successful project implementation is therefore a matter of honour.”
