The Sm5 electric multiple unit (EMU) is a low-floor train used on the Helsinki commuter rail network. Unlike other train types on the network, the Sm5 units are owned by Pääkaupunkiseudun Junakalusto Oy, a subsidiary of the cities of Helsinki, Espoo, Vantaa and Kauniainen. The units are leased to the Helsinki Regional Transport Authority (HSL), and VR operates them. [5]
