So I recently bought the N scale ex track first railroad track pack. Poorly documented. Basically no documentation.

Many question. What power pack would be the best to use with this pack. Need to control the turnouts. Second, my DCC system (bachmann golden spike) does not have the capability to control power turnouts. So what do I need to either power the turnout with the DCC system or to power the rail and turnouts with a standard DC xfmr. Any suggestion? how to kill two birds with one stone.

I am getting back into my n scale RR. All my cars and locos have the rapido couplers. The question is, was there ever a direct conversion kit from the rapido to the newer nuckler type. Meaning that I don't have to replace all the trucks to accomplish this. I know Bachmann has the ez mate type but in no way can one convert to these without a wholesale buying of appropriate trucks. Any suggestions?
