Stadler said the ‘landmark’ agreement is first tram order in Finland and strengthens its presence in the Nordic region.

Procurement began in 2021 through market dialogue with potential suppliers, and progressed as a negotiated procedure. CAF, Stadler and Škoda Transtech were invited to tender in April 2025, and final bids were submitted by Stadler and Škoda Transtech in July. Pääkaupunkiseudun Kaupunkiliikenne said Stadler’s bid was the only one that met the 1 600 requirements, which included technical matters, economic factors, environmental impact and the travel experience.

It said the Stadler trams to be manufactured at Siedlce in Poland represent proven technology and have affordable lifecycle costs.

‘We are convinced that the type of tram that we selected is the best possible for the demanding conditions of Helsinki’, said Pääkaupunkiseudun Kaupunkiliikenne Chair Eetu Kinnunen.

The metre-gauge trams will be based on Stadler’s proven Tango platform, tailored to Helsinki specific needs. The styling has been developed in collaboration with Helsinki-based design and innovation studio Aivan to provided ‘harmonious integration’ with the city’s urban architectural character and visual identity.

The trams will feature a modern design, increased seating capacity and enhanced passenger comfort, with measures for energy efficiency including lightweight construction and systems to optimise driving. They will be designed for a long service life, with the use of durable materials, zero-emission steel and components with high recycled content helping to minimise the environmental impact throughout their lifecycle.

‘Passengers can look forward to a comfortable, modern tram that meets the highest standards’, said Ansgar Brockmeyer, EVP Sales & Marketing at Stadler.
