I did some research on who sells frogs, etc. for modeling overhead. My source came up with (Thanks RC!)--
O scale--Ed Miller--Current Line Models-- http://www.currentline.net
HO scale-- George Huckaby-- http://www.trolleyville.com
Can you explain about the "frogs". Does the Car weight pull the Pole along the wire and through a turnout?
I bought 5 -3' pieces of K&S Brass Rod to make my first Poles with.
