NS DDZ (Full name: DubbelDekkerZonering) were built by Waggonfabrik Talbot (momentarily a part of Bombardier), 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. A 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.
The trains were formerly known as NS DD-AR (full name: Dubbeldeksaggloregiomaterieel) From 2009 the NS DD-AR were modernised to transform them from Sprinter to Intercity.
