I just purchased my first train set - a Bachmann DCC set with two locomotives. I have two questions that I've not seen in the forum. First, I have a crossover and turnouts which have green wires to hook up to an electric switch. Where does the power come from to operate these switches? I see no way to connect the red wires to my DCC controler. Second, I see there are #5 turnouts and #6 turnouts. What is the difference between these turnouts? Thanks in advance for the help. My grandson will be here tomorrow for a visit and I can't wait to show him "our" train set.
