NS DD-AR, full name dubbeldeksaggloregiomaterieel, were built by Talbot or De Dietrich and Adtranz between 1992 and 1998. They are operated in the Netherlands by the Nederlandse Spoorwegen. This class is a type of an electric multiple unit and was delivered in two batches as DDM-2 and DDM-3 resembling the bilevel rail cars series DDM-1 from 1985
These are the driving trailers at the end of the sets. Each set features them. There are 79 coaches, they are 26.89 metres long and seat entirely second class. They can seat 120 people, 64 on the upper deck, 52 on the lower deck and 4 near the doors. They also feature a toilet.
Numbered 270 7001 - 270 7079
These are the coaches connected to the ABv, Bv, mDDM or the locomotive. Each set features them, either one or two. One if with an mDDM and 2 if with a Class 1700. There are 103 coaches, they are 26.40 metres long and seat entirely second class. They can seat 140 people, 64 on the upper deck, 64 on the lower deck and 12 near the doors.
Numbered 280 7201 - 280 7302, 280 7508
280 7508, which was converted from first and second class to second class only seats 124, it was previously numbered 380 7508
These are the coaches connected to the Bv and Bvs. All sets feature one. There are 76 coaches, they are 26.40 metres long and seat both first and second class. They have 64 first class seats and 60 second class seats, for a total of 124 seats, 56 on the upper deck, 56 on the lower deck and 12 near the doors. The first and second class seating is the same on both decks, 32 first and 24 second.
Numbered 380 7501 - 380 7507, 380 7509 - 380 7577
These are the motor coaches connected to the Bv. 50 sets features one. There are 50 of them, they are 21.39 metres long and seat both first and second class. There are 16 first class seats and 48 second class seats. They can seat 64 people, all on the upper deck, slightly lower than in the other coaches. There are no lower deck seats, as this is where all the electrical equipment is kept.
Numbered 390 7701 - 390 7750
- A set made up of Bvs + ABv + Bv + mDDM can seat 448.
- A set made up of Bvs + ABv + Bv + Bv + 1700 can seat 588.
A formation of Bvs + ABv + Bv + Bv + 1700 has a set number of 74xx and the last two digits are the same as the last two on the Bvs of the set. A formation of Bvs + ABv + Bv + mDDM has a set number of 78xx and the last two digits are the same as the last two on the Bvs of the set.
In 2009 NedTrain has started to modernise 240, including the 50 mDDM coaches, out of 308 coaches of the DD-AR rolling stock. The other 68 coaches will be taken out of service and subsequently sold or scrapped. The modernisation will transform the coaches to modern Intercity trains, which will be used as EMUs. The new name of the DD-AR is NID, which stands for 'Nieuwe Intercity Dubbeldekker (New Intercity Double decker)'. The upper decks will be quiet, meant for working purposes whereas the lower decks will be for fun and enjoyment. The 240 modernised coaches will form 30 EMUs consisting of ABvs + Bv + ABv + mBs (mBs = mDDM) and 20 EMUs consisting of ABvs + Bv + ABv + Bv + ABv + mBs; so a total of 50 EMUs will be formed. The first new EMU will come into service in 2012, the last EMU in 2013. After the modernisation of the DD-ARs, the 1700 series locomotives will no longer be used, since all new NID trains have a mDDM powercar.
The DD-AR is normally found in great numbers around Amsterdam, Hoorn, Uitgeest, Haarlem, Schiphol, Weesp, Almere, Lelystad, Amersfoort, Utrecht, Rotterdam, Den Haag, Leiden, Dordrecht, Roosendaal and Breda.
They rarely operate north of Zwolle, east of Amersfoort (towards Apeldoorn), east of Utrecht (towards Arnhem) or (south)east of 's-Hertogenbosch (towards Nijmegen and Eindhoven).
