Scott,

The photo certainly looks like Cranberry Grade.  The quad hopper is a B&O, judging from the location and shape of the lettering and herald - probably from one of the W-2 classes.  The 325156 twin is not familiar.  My Jan 1952 ORER says 799 cars, 31'-6" IL, 10'-8" to the top of the side chord, and 1790 cuft.  The USRA twin was 30'-6" IL and 1880 cuft for comparison.
