Stadler and Finnish public transport operator Pääkaupunkiseudun Kaupunkiliikenne Oy have announced the signing of a contract for the delivery of a set of 63 TANGO Nordic trams.
This will mark Stadler’s first tram order in Finland, and the contract also includes an option for up to 120 additional vehicles and service provisions spanning more than 30 years – such as technical support, spare parts supply and the establishment of a local spare parts warehouse.

An initial contract between the two parties was first signed in October 2025, and all new trams are set to enter operation within the Helsinki metropolitan area, contributing to the expansion of public transport in the Finnish capital region.
Ansgar Brockmeyer, EVP Sales & Marketing and Deputy Group CEO of Stadler, said:This order marks Stadler’s entry into the Finnish tram market and represents an important milestone for our company.
Stadler has decades of experience in developing and manufacturing trams. Our vehicles have proven their reliability in a wide range of operating conditions around the world. We are now bringing this expertise to Helsinki, developing vehicles that meet the demanding requirements of Finnish tram operations.
Designed for use Nordic climates; the trams for Greater Helsinki are based on Stadler’s existing TANGO platform. The vehicles will be further developed to handle the requirements of urban operations in the capital region, as well as for reliable service in both extreme cold and icy conditions – with these requirements set to be reflected in the development of all key systems, including the electrical equipment and mechanical structures.
At between 31 and 34 metres long; the trams will sit at 2.4 metres in width, and have been designed specifically for Helsinki’s metre-gauge network, with particular attention being paid to the bogies and suspension system. Their fully low-floor design will provide step-free access throughout, and each tram will be capable of carrying between 70 and 90 seated passengers whilst offering two wheelchair spaces and a multifunctional area.
Aesthetically; the vehicle design was developed in collaboration with Nordic design studio Aivan, and seeks to reflects the architectural character and visual identity of the Helsinki region in an effort to allow the new trams to blend harmoniously into the urban landscape.
In order to fully adapt to their working environment, the TANGO Nordic trams utilise four powered, freely pivoting bogies with rigid axles. This enables running gear to adapt to the track geometry, ensure smooth operation and reduce overall wear on the tracks.
The trams will also be equipped with modern traction technology that recovers energy during braking, stores it temporarily and reuses it during acceleration – this is used to both improve energy efficiency and reduce overall energy consumption, reducing operating costs throughout the vehicles’ service life.
Delivery of the TANGO Nordic trams is scheduled to begin during 2029, and all vehicles will be manufactured at Stadler’s plant in Siedlce, Poland. This site has long-been producing trams for public transport operators across Europe, and its track record includes numerous completed and ongoing tram projects, including those for customers in Germany and the Netherlands, as well as in Kraków, Ostrava and Sarajevo.
