I was looking at a photo from the 1930s of the electric tunnel motors towing trains in and out of the East Portal of the tunnel. I noticed a small siding just outside the portal that ended at the road crossing and ran next to that building at road's edge. What was this siding used for? Was the building a freight house or MOW shed? The photo shows a boxcar and flatcar there; the switch must have been just outside the tunnel mouth.
