The Sm4 electric multiple unit (EMU) is a low-floor train used by the VR Group for longer-distance Helsinki commuter rail services. The initial order was for ten EMUs with the first unit entering service in 1999. Another 20 units were ordered in 2002 and the deliveries were completed in 2005.

The Sm4 is designed for longer-distance trips than typical metro-like local services. The Sm4 units have largely replaced the older Sm1 and Sm2 units on commuter services from Helsinki to Riihimäki and Lahti. The units are also used in commuter traffic on the Tampere–Riihimäki and Riihimäki–Kouvola routes. The Sm4s were also used for the shorter, frequently-stopping services because of the lack of more suitable low floor trains. The new Sm5 low floor trains that started to enter commercial service in November 2009 have completely replaced the Sm4 units on the short routes.

Nickname

Some railway enthusiasts use the nickname Pupu ("Bunny") for Sm4.
