Thanks for the info Jim I have been looking at building a catenary and when I saw your suspension system and wondered about the single wire. I assumed it was not powered.
Is there some type of sheave on the trolley pole which keeps it on the wire. I seem to remember those poles "popping" (coming off the overhead wire) and then dropping down to the top of the car.
Since the last trolley ran in June 1958, while I was on this planet at the time, I cannot image forming that clear a memory at that age. Wow, the interweb is a great thing. It happens I was remembering "trolley buses". They used overhead power but did not rely on rails running instead on tires. Whether you call them trolley buses, trolley coaches, or trackless trolleys, rubber-tired buses with overhead wires were used in Chicago from 1930 to 1973 and were very popular.
