I have none at this time, but hopefully I will have one in the near future. I did have some years ago but when I had the opportunity of using my trains to start a public Christmas display at a volunteer fire station 35 years ago I had to dismantle the one that I had in my basement to bring the display together.
My goal was to have as much moving as possible. We started off with a 10' x 32' display and it has grown to 22' x 44'. The last year that I was involved with was in 2007. But in 2004 I had 18 trains and 2 trolleys each operating on their own tracks and on 7 different levels. I even designed the display to have a 6' wide walkway right thru the center of it.
But right after they opened to the public last year I have decided to go back and help them out again. Last year they had 9 trains operating by DCS, so maybe they will have more running this year.
I just wish that I had the room to put a large layout together. I have to at least wait for my youngest daughter graduates next year to see what the future will hold.
Anyway here are some photos of that 20 rail display.
