shurlock1 posted:Dan I put catenary up on my dining room table for Christmas. It was hard to put up for a temporary layout. I used it for a non scale GG1 set. Its hard on turns such as 031 track for the wiper to touch contact wire. I also had to use two sided tape from home depot that had, I think 9 lbs sticking. It took a few hours so if this is for the temporary fix make sure you have time, larger diameter track I believe would be easier.
I would imagine a temporary set-up to be difficult as you say. When I was a kid, my buddies father brought home a trackless trolley system for him. It was unique. We tried setting it up on a table, but could not fasten the masts down. I've seen the same item on Youtube I think. I have also seen larger scale systems on Youtube.
O31 curves would make it even more difficult to do, as you have said.
