Articulations and double deck vehicles are generally not compatible.
In all of the variations of double deck railway carriages I have
encountered, none has gangway connections on both levels.

No, though SBB's double deck IC stock has the gangway well above the
(traditional screw) coupling, probably about a metre or so.


There is actually a Talgo prototype train that has gangway connections
on both levels. It was built as a concept demonstrator for Finnland
but no orders ensued. AFAIK the prototype is still in store somewhere.
