VR Class Sm7
Class of Finnish electric multiple unit trains
From Wikipedia, the free encyclopedia
The Sm7 is a class of 4-carriage electric multiple unit trains planned to enter service on the VR commuter rail network starting in 2026.[1][2] The trains are based on the Stadler FLIRT platform (same as the urban Sm5 trains) and are assembled in Poland.[3] They will replace the Sm4 trains on the D, R, T, Z and M routes which will in turn allow the non-accessible Sm2 trains to be retired entirely.[4][5]

The first Sm7 train was delivered to Port of Hanko, Finland in May 2025. Four additional units were delivered before the units entered in commercial service, and the full initial order is due to be in service in early 2028.[1][6]
The sets are owned by Railstock Finland, a government-owned rolling stock leasing company, and are leased to VR Group at least until 2030.[1]
