I was just at the place you are talking about. I forget the name. It is on Rte. 30 a block or so past the roundabout, next to a hair salon. It is on your way to the Seminary school.
There is a PINK train out in front of the house, and inside it's basically some guy's house, packed to the gills with stuff, Lionel mainly, lots of older stuff.
If you hit the Pizza Hut you have gone too far. Parking was limited, we parked behind the hair salon and I popped in for a few minutes.
