OK, so I'm not crazy (not legally, anyway! ;-)
I only saw them in a large yard, in Edmonton, near the airport. Never
on the roads...and I don't think I ever saw a 'real' "B" unit before
the pictures I saw today. (In the SF Bay Area, I'm on one of the oldest
commuter corridors, but the freight typically stops in Oakland, so we
don't see many big freights on the peninsula heading for SF.)
Maybe I saw one as a kid, but that seems such a long time ago.
(That *WAS* after Steam, thankyouverymuch! ;-)
I'll play back the video, and see if there is a good shot of the
connections between units. (I don't think I saw them moving....)
