Poland’s regional rail operator Koleje Mazowieckie has signed a contract with Stadler Polska for 11 additional FLIRT electric multiple units, completing the largest rolling-stock investment programme in the company’s history.
Final Contract Completes €75-Train Framework
According to Stadler, the latest contract follows earlier orders for 64 trains and marks the final step in a multi-year modernization program for services across the Masovian Voivodeship. The first of the new trains are expected to enter service in April 2026. Beyond vehicle delivery, the contract also covers maintenance services, technical training for staff, and repair packages, aimed at supporting long-term fleet reliability.
Adam Struzik, Marshal of the Masovian Voivodeship, said the investment reflects a long-term commitment to fleet renewal. "Mazovian Railways is one of the most modern regional carriers in the country, partly because they are constantly investing in new rolling stock," he said, adding that the full programme will deliver 75 new trains.

Production in Siedlce and Expansion of Poland’s Largest FLIRT Fleet
As reported by RailwayPro, all 11 trains will be built at Stadler’s plant in Siedlce, with local suppliers involved in production. Stadler Polska chief executive Radosław Banach said the completion of the framework agreement allows the company to continue expanding its Polish operations, noting that nearly 400 new jobs have been created this year, with the engineering team now numbering around 100 specialists.
Production of the previously ordered 64 units is progressing on schedule, with 25 trains currently in manufacturing, commissioning, or type testing. Once all deliveries are completed, Koleje Mazowieckie will operate 146 FLIRT trains, making it the largest FLIRT fleet in Poland.
The electric units are designed for regional services between Warsaw and towns across Masovia. They are built with lightweight aluminium bodies, can reach speeds of up to 160 km/h, and are equipped with air conditioning, passenger information systems, Wi-Fi, CCTV, and onboard defibrillators. All trains are fully accessible for passengers with reduced mobility.
The cooperation between Stadler Polska and Koleje Mazowieckie dates back nearly 20 years. FLIRT trains first entered service on the network in 2006 and remain in regular operation today.
