NYDEPOT,
I found this thread while doing a Google search for information related to the Erie freight houses at Jamestown NY. I can't tell you how glad I am to find someone who is interested in this besides me. Here are some of the things I have found, hopefully, they will be helpful to you.
I have 4 pages from the 1930 Sanborn Fire Insurance Map of Jamestown, NY, Vol. 1 in jpg format on my computer from research I did in a university library that had a subscription. Together they show the Erie Railroad Inbound and Outbound freight houses and the track arrangement that supported them.
I believe the building you can see on Google Earth is the concrete portion of the Inbound Freight House:

I believe this photo is the west end of the Inbound Freight House:
Southwest corner and south side of the Inbound Freight House:
?? East end of the Inbound Freight House with Allied Furniture Co. in the left background ??
If you have been able to collect information that supports or corrects this, please let me known.
