DMUjunayksiköt
DMUjunayksiköt is a Finnish term referring to multiple-unit train sets. These are rail vehicles made up of two or more permanently or semi-permanently coupled carriages that function as a single train. Unlike locomotive-hauled trains, DMUjunayksiköt have their own propulsion systems distributed throughout the set, often in one or more carriages. This design allows for greater flexibility in train length and passenger capacity.
The propulsion can be diesel, electric, or a combination. Diesel multiple units (DMUs) are powered by diesel
