Surefire posted:You can see the B unit in the color photo posted a few posts above if you zoom in. Notice how the A unit looks extra long. If you zoom in there's a paint matched piece in-between the units.
In that photo above, the "b"unit that you seem to reference to with those 8 square windows near the "end" appears more like a building attachment to the rear of the "A"unit carbody rather than a "b"unit.
If it was a true "b"unit, I doubt that EMD could fit those 8 square windows in that configuration in relation to the structural supports on how a "b"unit carbody is built. In other words where's the angled steel beams behind the glass? I don't see any.
