The 4DD was a completely different design, with individual compartments leading to narrow staircases for commuter services. The TGV-M has a vestibule at each end (a 'long distance' layout) as per most European DOuble-deck stock.So the same issues which led to the Bulleid 4DD sets being withdrawn! Lack of space overall and very likely will lead to even longer boarding/disembarking times
