Finland is investing in its public transport infrastructure through new rolling stock and maintenance equipment. RailStock Finland Oy has exercised a contract option to purchase 21 additional Stadler FLIRT electric train units, bringing the total order to 41 Sm7 type units. These trains are designed for extreme climatic conditions, featuring enhanced thermal insulation, floor heating, and oversized snow plows.

In addition to the new trains, maintenance capabilities are being expanded in Helsinki. Plasser & Theurer has delivered a specialized 08-275/4 ZW maintenance vehicle. This machine is designed to service both the metro and tram networks by operating on two different gauges: 1,524 mm for the Finnish railway and metro, and 1,000 mm for the Helsinki tram system.
