Wiring an Atlas Switch with a Plastic Frog in a DCC Environment
Tom has this question for readers:
“I use Tortoise switch machines to control my HO switches. I would like to use the switch machine to change the current for the switched rails but don’t know understand where to connect the changing current lead from the tortoise as there does not appear to be a common point for both rails coming off the frog. Do I just solder is to both of the rails coming off the frog or is there a better/more correct way to do it?”

To my knowledge, If you are using an insulated frog turnout (plastic) there is no need to change the polarity.That would only be needed for a live frog turnout. you can use the Tortoise switch machine for switch action alone.
