the desiro can be made as a diesel or electric multiple unit (dmu or emu). it is normally made as two and three-car trainsets. although there are many differences between single trains, the basic body design is the same. these trains are mostly used for regional services, and belong to a new generation of light, modular trains which have become common in many european countries. they are sometimes thought as light regional railcars. they are mostly cheap to make and work. their fast acceleration makes them good for services with short intervals between stations. however, they are sometimes complained by people for their poor passenger comfort.
