Yep, this is South Hammond, at the north end of the north yard, south of 165th Street, at about Vine street I'd say. Lyman street is to the right and parallels the yard. The NW-2 is kicking cars. I used to hear them working day and night as a kid living at Jackson and Vine.
Revving up... silence .... and the light (or not-so-light!) BOOM of the car(s) hitting the standing cut, over and over.
I feel for the switchmen, it sure looks cold in this photo!
