The DB BR 425, a 4-coaches long efficient and light EMU was ordered by Deutsche Bahn in 1994 and built, beside the suburban-specific DB BR 423 for German S-Bahn services, by a consortium of Siemens, Adtranz/Bombardier and the DWA (Deutsche Waggonbau AG). The difference to its siblings, the DB BR 423 and 424, is that this type of EMU was built for normal stopping services. The equipment is slightly different: each car has one door less and one of the two motorized cab cars was fitted with a lavatory, that is handicapped accessible.
