Project

The loan will be used to finance the acquisition of 13 new double-decker trains from the Swiss manufacturer Stadler on behalf of Mälardalstrafik AB. The new trains will be delivered starting in spring 2028 and are expected to enter service between 2028 and 2029. 

Mälardalstrafik operates regional trains in the Mälardalen region, carrying over 15 million passengers each year. The investment will strengthen the capacity and reliability of the fleet, helping to meet growing transport demand and ensure stable operations as services expand. 

Fulfilment of NIB's mandate

Productivity 

Swedish railways face underinvestment and congestion, leading to frequent delays. To meet rising demand, Mälardalen will add 13 double-decker trains, increasing seating by 22% and improving peak-hour service to support workforce mobility. Urbanisation continues to drive rail travel growth and the need for more rolling stock. 

The investment aligns with long-term regional development plans, enabling to offer more flexible scheduling and greater capacity. The Stockholm–Mälardalen region, home to over 4 million people and generating nearly 40% of Sweden’s GDP, depends on efficient transport links to connect its cities and labour markets. Strengthened rail connections will help balance housing growth, ease pressure on Stockholm, and promote development across the seven counties.
