History
At the beginning of the 1950s it became clear that VR needed multiple units to compete with buses in short-distance traffic. In 1952, seven Dm6s were ordered from Valmet, and eight more the next year.
After testing the Dm6:s and having noted that the new DMU:s worked well in Finnish conditions, VR ordered more units. In total, 197 Dm7 class multiple units were built with some modifications (a larger wheel size, for instance).
Variants
DmG7
Three Dm7:s (numbers 4145–4147) were transformed into goods transport vehicles. They were withdrawn in 1981.

16 Dm7:s were transformed into electric maintenance vehicles.

All Dm6:s have been withdrawn from service. 20 Dm7:s are preserved by Finnish museum railway associations.
