VR Class Dm7
The Dm6 and Dm7 were diesel multiple units built by Valmet in the 1950s and 1960s for Valtionrautatiet.[1] They are known by their nickname lättähattu (Finnish for "flat cap", the first widespread youth culture movement in Finland).[2]
History
At the beginning of the 1950s it became clear that VR needed multiple units to compete with buses in short-distance traffic.[3] In 1952, seven Dm6s were ordered from Valmet, and eight more the next year.[3]
After testing the Dm6:s and having noted that the new DMU:s worked well in Finnish conditions, VR ordered more units.[4] In total, 197 Dm7 class multiple units were built with some modifications (a larger wheel size, for instance).[4]
Variants
DmG7
Three Dm7:s (numbers 4145–4147) were transformed into goods transport vehicles. They were withdrawn in 1981.[5]
Ttv
16 Dm7:s were transformed into electric maintenance vehicles.[6]
Preservation
All Dm6:s have been withdrawn from service.[7] 20 Dm7:s are preserved by Finnish museum railway associations.[8]
No:4020 is at the Finnish Railway Museum.
