Following the announcement of the contract award in October 2025 and subsequent disputes, Stadler and Finnish public transport operator Pääkaupunkiseudun Kaupunkiliikenne Oy (PK) have signed on 11 November 2026 a contract for the delivery of 63 TANGO Nordic trams. The contract also includes an option for up to 120 additional vehicles and service provisions spanning more than 30 years. These cover technical support, spare parts supply and the establishment of a local spare parts warehouse.
Ansgar Brockmeyer, 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. We are now bringing this expertise to Helsinki, developing vehicles that meet the demanding requirements of Finnish tram operations.”
The trams for Greater Helsinki are based on Stadler’s proven TANGO platform. The vehicles will be further developed for the demanding requirements of urban operations in the capital region as well as for reliable service in extreme cold and icy conditions. These requirements are reflected in the development of all key systems, including the electrical equipment and mechanical structures. Particular attention is being paid to the bogies and suspension system.
The 63 trams are between 31 and 34 m long, 2.4 m wide and designed for Helsinki’s meter-gauge network. They feature flexible interior layouts that can be adapted to different operational requirements and passenger needs. Depending on the configuration, the three-module vehicles will provide between 70 and 90 seats and will be equipped with two wheelchair spaces and a spacious multifunctional area. Their fully low-floor design will provide step-free access throughout the entire length of the tram, making travel easier for people with reduced mobility as well as passengers with prams or bulky luggage.
The vehicle design was developed in collaboration with Nordic design studio Aivan. It reflects the architectural character and visual identity of the Helsinki region, allowing the new trams to blend harmoniously into the urban landscape. A distinctive technical feature of the TANGO Nordic trams are their four powered, freely pivoting bogies with rigid axles. Thanks to the articulated bogie frame, the running gear can adapt to the track geometry. This ensures smooth operation and reduces wear on the tracks, even on demanding routes with tight curves.
The vehicles will be built at Stadler’s plant in Siedlce. Delivery of the TANGO Nordic trams for testing is scheduled to begin during 2029.
Stadler will also provide contracted services through its local service facilities. The company employs around 700 people at 15 locations across the Nordic countries and operates four service locations in Finland. Through the long-term service agreement, Stadler will help ensure the reliability and operational efficiency of the TANGO Nordic trams throughout their entire lifecycle.
