Alan,
Great Website for your railroad. I've been to the Orrville Depot several times. Near Thanksgiving Weekend they always have an open house, along with open houses for several other area model railroads. Check out the "Route 30 express". Most likely will be cancelled this year
I grew up about two miles from the Pennsylvania yard and Roundhouse in Crestline, Ohio. Saw it decline and then be torn down. The yard became a roadrailer facility for a while, now is a large grain loading facility. Usually see about 20 -40 covered hoppers on the tracks. As a side note, we also lived in Marlette Michigan for a couple years in the 80s when I was a driver for Schwan Foods. Was back up there last July on vacation. Small World!
