That was kinda cool! The engineers were loading up for an extended trip, and sat there while I finished taking pictures several minutes after they were done loading up.
They rolled away a couple seconds after we got back in and were looking at the pictures. I gave 'em a wave out the window and they blew the horn.
I always thought it would be fun to ride in one of those.
Taken right outside the bnsf yard in down town Vancouver.
