I see the Legacy controller pictured in the American flyer catalog. I'm thinking of ordering it. I'm wondering how the engine could get it's signal from two rail track if the engine gets turned around?
If the signal is applied to the neg rail on my dcs layout and the engine sees the signal, what happens if I physically turn the engine around? Will the engine still work? Do I need a reverse polarity switch in the engine? How do American flyer engines work? Maybe the engine still gets it?
Thank you for any help.
