|AT&SF E6 15 at Albuquerque, New Mexico, circa 1942, photograph by Jack Delano, image from the Library of Congress ( LoC ). The description at the LoC was: Santa Fe R.R. streamliner, the "Super Chief," being serviced at the depot, Albuquerque, N[ew] Mex[ico]. Servicing these diesel streamliners takes five minutes.
Number 15 was built in May 1941 ( c/n 1242 ), retired and traded to EMD in June 1968. Note it was equipped with a visor over the headlight, which I believe was installed to make the light less noticeable from the air, the fear being air raids from Japan during World War II. I count 11 men servicing the locomotives, although one man is carrying a grip bag, so maybe he is part of the locomotive crew. Also of interest ( to me ) is the man on the right stacking white bags on a baggage cart, and he is standing on something that is covered with a white fabric cloth.
