Helsinki Transit Operator Signs Deal with Stadler for 63 TANGO Nordic Trams

(Railfanning.org News Wire) — Swiss rail vehicle manufacturer Stadler has secured its first tram contract in Finland after signing an agreement on Nov. 11 with Greater Helsinki transit operator Pääkaupunkiseudun Kaupunkiliikenne Oy to supply 63 TANGO Nordic streetcars.

The contract includes options for up to 120 additional vehicles, along with a comprehensive maintenance and spare-parts support agreement spanning more than 30 years. Stadler will manufacture the meter-gauge, 100% low-floor trams at its facility in Siedlce, Poland, with initial test deliveries scheduled to begin in mid-2029.

Designed for extreme Nordic winter conditions and Helsinki’s tight urban track geometry, the three-section streetcars measure 31 to 34 meters long and feature four powered, pivoting bogies with rigid axles. The vehicles will seat 70 to 90 passengers, include regenerative braking systems to store and reuse energy during acceleration, and feature exterior styling developed in partnership with Nordic design studio Aivan.

While the order represents Stadler’s breakthrough into Finland’s streetcar sector, the company already maintains an established presence across Northern Europe. Stadler employs approximately 700 workers across 15 Nordic service sites—including four locations in Finland—and has previously delivered more than 400 rail vehicles to the region, including over 120 FLIRT commuter trains and locomotives for Finnish operators.

Helsinki’s meter-gauge tramway network ranks among the oldest continuously operating electric streetcar systems in the world. First introduced with horse-drawn cars in 1891 and electrified in 1900, the system carries tens of millions of passengers annually and undergoing major network expansions across the metropolitan region.
