I am also a 2 railer but I love going to York. It’s true you won’t find much 2 rail equipment there and the 2 rail equipment can be in any hall. There is a vendor who is always in the Orange Hall. His name is Howard Serig and he almost always has only 2 rail equipment on his tables. He is located slightly down an aisle somewhat close to the Lionel display. Over the years I have bought 2 locomotives from him and a bunch of cars. He is a great guy with prices that are fair.
I go to York to see the manufacturers displays, see old friends, and basically look for things that pertain to both 2 rail and 3 rail like structures but everyone is different. Last April York I found a US Hobbies NYC Niagara in the Orange Hall (not at Howard’s table) for $700. I wanted it but didn’t have enough money with me.
Just wanted to give you some information. If you want to see a lot of 2 rail equipment you will be better off going to Strasburg which is a great show. I usually don’t go to that because I work weekends and I don’t really need more trains.
