Greetings all. I just pulled my father's 70+ year old standard gauge lionels out of my mother's attic for my kids to enjoy - as I did when I was a kid. He always used to hook up a signal which would stop, and then ultimately release the train.
Problem is, my father died a couple of years ago. And while I still have the signal - he took the knowledge as to how it gets hooked up with him. From what I can see it is referred to as a #78 block signal - it has a green and red light like a traffic light - and a three wire track connector. I know the trick is insulating the track - but I can't remember how it is done. Does anyone have any knowledge of this accessory and how it operates?
Thanks for any help to the new guy!
