l NS mDDM - EMU and Coaching Stock
The Netherlands Double Decker coaching stock has an interesting history and is intertwined with that of the Class 1700 loco and mDDM power cars that were specifically built much later to haul them. Both mDDM and DDM coaches are covered here

The DDM stock was built for service in the province of North Holland which hasd been experiencing high passenger growth with restricted length platforms. After trials with French double decker stock had been tested, this new design was constructed by Talbot at its Aachen factory in Germany.Very wide doors are fitted at the coach ends and access to both levels is by staircase. The trains are either powered by Class 1700 or mDDM power cars. Driving trailers are fitted with pantographs that can beraised when not coupled to a driving unit to power the on board systems

Of the original build, 14 type Bv coaches were rebuilt into bycycle coaches for use on trains between Haarlem and Eindhoven/Maastricht. During the summer the lower deck seats are removed to stow bikes. The seats are put back in for the winter but are most uncomfortable on these long distance services

The original series of DD-AR coaches is expected to be withdrawn in September 2010. The remaining 250 DD-AR coaches including the motorcars will be modernised and will get a new livery as well. There are going to be 25 sets of 4 cars and 25 sets of six cars which will be used for Intercity services. The first modernised set should be ready by the end of 2010 and the last one in 2013 and will be designated as DD-Z.
