The B&O used to set up a train display at the CG&E/Cinergy/Duke building in downtown Cincinnati, OH from Thanksgiving to New Year's. My Dad and I would make a day trip out of it by visiting the large layout, eating lunch, and visiting a hobby shop or two along the way. What memories!
Now, the layout is housed & displayed at the Cincinnati Union Terminal.
Here are a few pictures over the years of B&O and C&O stuff.
Enjoy!
