Very cool shot, but I think that forth unit out is a AC6000.

Will: The unit is UP No. 7064, which is a 4,400 hp “convertible” that was never converted to 6,000 hp. I think UP called them C44/60AC or C6044AC at the time. These so-called convertibles do have the large radiators of the 6,000 hp. units though.

Wow I knew that most if not all the AC6000s were converted but I never knew that some never even had 6,000 hp. Thank you for the info, you learn something new everyday!
