NS DDZ

what is it?

NS DDZ (Full name: DubbelDekkerZonering) were built by Waggonfabrik Talbot (later a part of Bombardier, which in turn sold its railway section to Alstom), De Dietrich Ferroviaire (now Alstom DDF) and Adtranz between 1992 and 1998 and are operated in the Netherlands by Nederlandse Spoorwegen (NS). This class is a type of a power concentrated electric multiple unit and was delivered in two batches as DDM-2 and DDM-3. The trailer cars of this multiple unit can also be operated with a Class 1700 electric locomotive instead of a motor car, forming a push-pull train.
