Years ago I purchased 2 very nicely restored restored 500 cars at a show. Having no standard gauge stuff, It took a while to figure out what I was going to do with them. I finally decided to try an alternating 72" layout under the tree.
Kirk from USA track sent me the track and I added the Lionel corp repro switches. The track radius was perfect to my template cut on CNC.
I added small quarter turn connectors to allow the layout to reduce to 4 pcs
I painted the plywood, ran a jumper wire form switch to switch and attached the track.
I picked up a trolley and 4-4-0 steamer to pull the old cars
The test run took a bit of tweaking but finally worked the bugs out. (separate power supply to switches to get 14 volts) I would like to figure out how to slow down the trolley at some point.
The automation part uses 2 Lionel 153IR's with bridge diode and 12 volt relay. (article by Donald Miller)
I am very happy how it turned out so far, just hope everything works again when I set it up under the tree after the kids go to bed!!!
