Thanks for all the help and advice.  I'm enjoying getting started with the hobby and I want to get my track completely layed out and then start on the scenery and buildings.  I'm sure I'll have more questions.  Thanks again.

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.
