I'm certain among so many experienced electricians many of you have heard of a "trolley system". I live in an area with many older homes and knob and tube wiring is a daily sight. It is my understanding the trolley system is an "ancient" method for running three way lighting. I recently heard of this and was wondering if someone could explain the how it works, why it was used and is it legal by todays code standards. Thanks
