SD40-2 950 and SD45 907 at St. Louis, Missouri in August 1978.
The location is the Lindenwood Yard diesel shop service track fuel pad.
The view is looking northeast toward downtown St. Louis. In the distance, by the yard tower, one can see the Arsenal Street overpass over the yard. To the left beyond the trees, on the north side of the yard, is the River Des Peres. This is near its junction with Deer Creek.
