N scale 42"x42" DCC layout attatched file. 11" and 19" radius curves. Atlas #6 manual turnouts. NCE Power Cab DCC system. There is only one wire from the NCE to the track; is that wire to connect to a wire block and wires on the wire block to the track? I don't see any reverse loops. The inner circle will be used for two sidings (one on each half of the circle. Do I need any insulated areas(at turnouts?) How many wire connections to the track do I need, and where? If it's too complicated to mark on the attachment layout on this forum and someone could copy the attached layout, mark the connections on it , and mail it to me, I would VERY MUCH appreciate it and wouldn't wire it wrong.
