Incidentally, I failed to draw attention to an error in the first post.
This is the first E3, EMD Demonstrator 822.
When it was delivered it had a standard headlight fitted. Comparing it with the E1 above in Penny's post, ATSF 8, or ATSF 4 just above, the three small radiator inlet vents compared to the two large vents on the E1 can be seen.
No 8 is on a sitting car train, either an El Capitan or a San Diegan.
