In the photo I posted, A would be furthest away, and E closest, yes:
So, to recap:
A-B: Yaw
B-C: Yaw
C-D: Yaw & Pitch
D-E: Yaw
7-module is 3-2-2; you can see the pitch articulations here pretty clearly, between C-D and E-F:
I feel like on the 7-module one, there must be a Roll axis in there somewhere - it's too long of a sausage to be totally rigid that way (frame stresses and all). I'll have to watch some more videos to see if I can spot any movement.
(The nomenclature for the modules might vary from operator to operator. I read through some of the maintenance manuals at the Leslie Barns open house for the TTC's new FLEXITY Outlook LRV's, and that's what it was in the manuals from Bombardier.)
