Thanks and we can end this thread now.

Thanks for all the replies! I like the idea that when I want to toggle on the NCE controller you can have designated almost any number up to 9999. So for each district I could have 2000, 3000 and so on. It is basically one control to get to the booster and then the number of the booster. But I can relate to the fact this might cost me a great deal of money. Currently I have 23 turnouts. But NCE just announced the Throw-it and Throw-8. If I use the throw-8 I would need only 3 decoder boards. Choices, Choices.

  All my track is EZ track and all my turnouts are Bachmann pre-DCC. I am going to use a NCE DCC system to control all of the turnouts using NCE stationary decoders. So first I noticed that I have 2 types of toggles, A) left or right and B) left or right then momentarily push. Are there two types of switch machines in use? If not what type am I using? (STALL or?)

Secondly, there are a combo of 3 green wires going from the switch machines to the toggles. Is the middle one a common or ground wire?
