VR Class Sm2 electric multiple unit

A total of fifty Sm2 units were built between 1975 and 1981 by Valmet in Tampere. Since the withdrawal of the older Sm1 units, the Sm2 units are the oldest multiple units in use in Finland.

All Sm2 units were completely renovated between 2002 and 2011. Only the bodywork and the technics remained mostly untouched. Many of the changes are visible to the passengers, including a different type of seat and modern toilets. Between 2018 and 2024, all remaining operational units were refreshed, with new moquette and a new livery consisting of a white bodyside with a green lower band, except for units 90 and 91, which remains in their vintage red livery.

The two-car sets (powered car plus driving trailer) can seat 200 passengers, have a power output of 4x155 kW = 620 kW or 830 hp and a maximum speed of 120 kmh.
