Thanks Dan.
the catenary towers are tinplate traditions MTH telegraph poles modified with a (K&S) square brass tube set horizontally and a smaller connective brass tube slightly bent at the tips soldered to horozontal square tube at a fortyfive ish degree angle to the vertical post And yes, very Live power to run my electrics. Made a pilot model and went from there assembly line production. The under side of the square tubing horozontal has a soldered at 90 degrees O scale track standard end of track connector clip through which I run inverted code 100 scale Rail. Modified the Lionel electrics to pick up overhead juice.
The good news is my buddy that I sold everything to years back recently gave more half of them back to me. I am in the process of cleaning them up. If I can get the original but newly modified old layout built again I will use them again.
i will look for assembly photos on old PC and share.
have a good week.
