There is a train shop in Defiance, Ohio, Phil's Hobby Shop. Mostly R/C with a smattering of trains last time I was there. They also have two shops in Fort Wayne, one is better for trains, located on Clinton, not far from the Coliseum. It could be worth the trip.
And there are quite a few train shows in the area, most in the fall and winter. A few are definite thumbs up!!
