Rob, thanks for the link. As shown on their page, Lynn's full name was Linda Anderson, and she went by Lynn. I will amend my original post with the link.
The store is an amazing shop. The present owner, Chris, wasn't there yesterday, and I know he is close to or past retirement age. For those of you who don't know, the original shop and owner was Nicholas Smith, who had the store in downtown Philly, and it was one of the first Lionel dealers in the country ~ dating back to early 1900s. Chris bought the name and store and moved it to Broomall, PA in the 1970s I believe. They used to display a portion of the G-scale display in the upstairs part of the shop - the very same display that the original Nicholas Smith and crew set-up every year at John Wanamaker's Dept. Store in Philly. I have fond memories of viewing that display when my family patronized center city at Christmas time in the early 1970s. Now, the shop has a smaller O and HO layout, which itself is pretty neat.
The train displays are first rate. For some reason, I always thought that the trains on those shelves looked better than my trains; I could never figure it out. Perhaps the shop's shelves being at eye-level and higher present the engines in a very prominent and grand way showing details that we don't see when standing slightly above while running trains on our layouts, which tend to be less than eye-level. Maybe it was the lighting, too. At any rate, I kind of feel sorry for younger people who only shop on-line and have never seen such a train shop. I read about train shops closing every year on the forum, and unfortunately the general trend in America has been the closing of Mom & Pop stores of every variety, in favor of corporate giants. Nicholas Smith is not your average Mom & Pop train shop, however. I reckon its one of the giants, but in a good way if you know what I mean. If you have a chance, visit Nicholas Smith sometime. Give yourself a couple of hours at least. I understand there's a separate warehouse as well, off location somewhere, that, if rumors among the staff at Nicholas Smith are true, house train treasures of unimaginable variety.
