Stadler delivers FLIRT trains for Mazovia rail expansion

Regional rail networks are expanding capacity and modernizing fleets to meet rising passenger demand and improve service reliability. In this context, Stadler delivered the first nine FLIRT electric multiple units to Koleje Mazowieckie, initiating a multi-year rollout of new rolling stock for the Mazovia region in Poland.

Early deliveries mark start of large-scale fleet rollout
The nine trains, manufactured by Stadler Polska in Siedlce, were accepted following required approvals and completion of monitored test operations without passengers. These deliveries form part of contracts signed in 2024–2025 covering a total of 75 vehicles, with 53 units scheduled for delivery in 2026.

The trains are expected to operate on regional routes including Warsaw–Dęblin and Warsaw–Skierniewice, supporting increased service frequency and capacity. The programme represents one of the largest rolling stock investments in Poland’s regional rail sector, supported by European Union funding.

Production scale and regional manufacturing impact
Manufacturing is being carried out at Stadler Polska’s Siedlce facility, which has previously delivered 71 FLIRT units to the same operator. The current contracts increase both production volume and output rate, with approximately one vehicle completed per week.

The programme contributes to local industrial activity through workforce expansion and supply chain demand, linking rail manufacturing to the broader digital supply chain of regional suppliers and service providers.

Fleet expansion and operational integration
With ongoing deliveries, Koleje Mazowieckie’s fleet is expected to exceed 120 FLIRT units by the end of the year. The contract scope includes not only vehicle delivery but also maintenance services, technical staff training, and operational support, enabling long-term integration into the operator’s network.

This approach aligns with lifecycle-based fleet management strategies, where rolling stock procurement is combined with service and maintenance frameworks to improve availability and cost control.

Train configuration and passenger capacity
The five-car FLIRT trains are designed with a high proportion of low-floor sections to improve accessibility for passengers with reduced mobility, as well as for prams and bicycles. Each unit accommodates up to 582 passengers, including 261 seated, and operates at speeds of up to 160 km/h.

Onboard systems include ETCS Level 2 for train control, air conditioning, CCTV, passenger information systems, and wireless internet connectivity. Safety features include emergency intercoms and defibrillators, supporting compliance with modern rail safety and operational standards.

Energy efficiency and design considerations
The FLIRT platform uses a lightweight aluminium structure, which reduces overall vehicle mass compared to conventional steel designs. This contributes to lower energy consumption during operation and supports reduced operating costs over the lifecycle of the trains.
