Focusing on the second photo in the group of enlargements of the Chalk Creek photo there are four short(or is it two long) SG width construction cars.Could they be hand me downs from the UP on narrow gauge trucks?I'm wondering if the glass plate still exists because it  is more or less impossible to make out any detail.I wonder if Ron Rudnick would have any info on these cars.
