Jerry,
Thank you for the warm welcome and accepting me into the group! I hope to attach some photos of the early days at Trolley Park. I had to go back and look for these photos and learned that I have been working on the park since about 2015. There was a year prior to that when I was working on building those brass poles to hold the overhead. I got a dozen of the them from Jim Rivers and proceeded to solder little fittings etc. At the time I had no idea of just what I was going to do with them. Then slowly my OCD took over and I was reading and pursuing a lot of information on traction systems. With my limited space and 027 turns I had created a bit of a monster for hanging the overhead. The last photo shows my technique for installing the Lionel animated accessories. I cut out the 1/2" homosote from the top of the table and dropped the units in. Then I could use Sculp-ta-mold (spelling = wrong) to blend them into the rest of the table. Now if any of those units fail, it is get our a knife and hammer and have at it. Anyhow for consideration:
