In May of 1943 Jack Delano made a brief visit to a Chicago, Rock Island and Pacific Railroad yard (presumably) in Chicago. While there he recorded some of the switching operations of a crew. Their power was this EMC Winton powered NW1 (relatively rare – only 27 were built). Note the headlight with a visor, and the steam locomotive style bell.

Looks like a couple of “suits” from the front office are observing the crew (or perhaps the locomotive) on this overcast day.
