Upon my arrival at the east end of Princeton yard to catch 112, I was surprised to find there were NO cars (especially auto racks) anywhere to be seen, it was wide open west towards Princeton and all the way east towards Hydes Chapel. That changed in the course of about 10 minutes. Stack extra train 24N as seen in the background pulled down on the main, 112 came in on yard track 3 and soon after, coal train 71T came up the siding followed by local train BP90 pulling racks and coil cars from Toyota.
