Underground Railroad Shop in New Castle, PA. Nice shop with lots of post war Lionel. Modern MTH and Lionel also.... new and pre-owned. Nice 50's - 60s music is always playing too! Lou Palumbo owns and runs the shop. Very nice guy! He writes a column for Classic Toy Trains. Although I don't subscribe to CTT I do occasionally pick up a copy at local train shops just to read Lou's article ... "Views from the Underground"
I always enjoyed visiting Mercer Junction Train Store whenever I was up that way. Great shop! Now with Dave closing the shop at the end of 20202, I don't have a reason to go to Mercer anymore.
I've never visited the other stores in the Pittsburgh area, suggested in this thread, but will do so next time I'm up that way.
