Don't recall any train stores where I grew up though there were seasonal displays in Sears & Roebuck (RIP) and Western Auto and Firestone Tire -- the latter two may also be gone by now. Hard to keep up.
I do remember Mom taking direct route across town, which meant waiting for the trains in downtown Charlottesville VA.

"C&O for Progress"
Might have been a subliminal message there but I didn't catch it at the time. I was too busy counting the railcars as they drifted past.
