The Sm7 is a class of electric multiple unit trains planned to enter service on the VR commuter rail network starting in 2026. The new trains will have 4 carriages per unit and they will be 50% more energy efficient than the older stock.[1] The trains are based on the Stadler FLIRT platform (same as the urban Sm5 trains) and will be assembled in Poland.[2] 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.[3] [4]
The first Sm7 train was delivered to Port of Hanko, Finland in May 2025. Three additional units are expected to be delivered during the testing phase which is scheduled to last until spring 2026.[5]
The Sm7 will have a modifiable interior, where if needed more bicycle spots can be added during summer and the trains have tables with the chairs, so using a computer is easier. The trains also have free Wi-Fi for all passengers and charging sockets for all seats.[4]
