I am using bachmann ez track for my whole layout. All of my turnouts are also bachmann. However, they turnouts don't work very well with derailments. So I purchased all tortoise machines to control my turnouts. I also have digitrax DS64's to control the turnouts. With that being said, there is a switch under the turnout. One wire (Red) goes to one set of rails, and the other wire (Orange) Goes to the other set. I'm sure that is so that you power the rails when the points touch that rail... (Something like that). However, the black wire goes to the frog. I assume the frog is powered depending on where the points are? So how do I wire this so that it works the same way with my Tortoise machines?
