Rolling stock renewal for Koleje Mazowieckie

Production is being handled by Stadler Polska at its plant in Siedlce⁠. The contract also includes 18 years of maintenance services, repair packages and training for Koleje Mazowieckie personnel.

Part of the train procurement is financed from the National Recovery and Resilience Plan, or KPO. The investment includes two main elements: an order for 11 EZT I units with PLN 323.4 million, or EUR 74 million, in funding, and a second contract for 10 EZT units valued at PLN 294 million, or EUR 67 million.

Stadler Flirt EMUs to Mazovia regional routes

The Flirt EMUs are being deployed on key regional routes in Mazovia, including services linking Warsaw with Łowicz, Sochaczew, Małkinia and Mińsk Mazowiecki.

Their introduction into service directly supports higher transport capacity, shorter journey times and improved reliability on regional rail operations.

Koleje Mazowieckie is one of Poland’s larger regional passenger operators. In 2024, Stadler said the operator ranked third in the country by passengers carried, ran about 800 trains a day and had 332 vehicles in its fleet. Stadler also said a 61-unit FLIRT ER160 order for Koleje Mazowieckie was completed in 2023, placing the current 75-EMU programme in the context of an existing Stadler-built regional fleet.
