Might as well keep this thread going...
The lights get their track power through wires that run from the trucks up to a brass "finger": this brass piece (in theory) contacts another piece of brass that's attached to the inside of the roof. This second piece has wires that run to the lights.
I wanted to make sure there was a good electrical connection between those brass pieces, and wanted to come up with something that wouldn't put undue upwards pressure on the roof as I want the roof to sit flush on the walls of the car.
I soldered a centering spring from a Kadee coupler on each end, as shown here:
They work great.
Now, a question: I want to convert this to 2-rail and have had these trucks for as long as I can remember:
I know they are insulated for 2-rail (I tested them). Can anyone identify these? They're pretty nice...
Thank you.
