The Siemens Desiro can be built as a diesel or electric multiple unit (DMU or EMU). It is normally configured as two- and three-car trainsets. Although there are various differences between individual 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 sometimes referred to as light regional railcars. They are relatively cheap to build and operate. Their quick acceleration makes them suitable for services with short intervals between stations.
