The Dm10 was an experimental diesel multiple unit built by VR Group's Pieksämäki workshop in 1994.

[1] It was based on a blue passenger carriage, Eit 23018, which was fitted with two diesel engines taken from HKL buses 601 and 608.

[1] The train had 80 no-smoking seats[1] and had the driver selling tickets, which was unusual for Finnish conditions.

[4] The unit was finally used in regular service for only three years, 1994 to 1997, mostly in regional traffic in Eastern Finland before being withdrawn.

[8] The nickname of the Dm10 is Junttilan Salama (Finnish for "Redneck land lightning").
