Could someone give me a brief summary of the pros and cons of the various methods of providing power and control to model trains? I.E., basic transformer vs R/C, DCC, command control and whatever else may be available.
This would be for use with an outdoor G scale layout, if that makes any difference.

Generaly yes, that was the idea. But now that I've given it some thought I see that it is a bit more complicated. First: THe power source can not be DC. DCC uses square wave AC power. There goes the idea of a simple battery to power the locomotive.
Second: You would need to separate the DCC control signal from the DCC power. Actually this may not be that difficult if you take the signal from the control bus, between the cab and the booster.
Trying to kludge a DCC system into a wireless system with DC power is probably not a good way to go. But if a manufacturer were to market a purpose built decoder with a radio link that could run on DC power... Now that would be somthing. And very feasable.
Which is essentially the same, radio control with batteries, using DCC as part of it allows some common components, such as decoder. The radio reciever needs to deliver the dcc signal to the decoder which can get its power from a battery. See

Sure it could be done. But that adds one more thing that can fail. A purpose built DCC controler could be designed with an 'H-Drive' motor control. THat would allow the motor to be controled in either direction with a simple DC source.
I don't think they got lost, I just think no one answered because there is no such product. You can certainly do it, but you will have to cobble together a system from existing airplane and model car systems and adapt it yourself to your model railroad application.
From the text of your question ". . . sound/lights/smoke . . ." it sounds like you are running O gauge tinplate with AC track power. You can use DCC with tinplate, but you need to get answers from other tinplaters who have adopted DCC to operate their trains. A good place to go in addition to this board is the Digitrax users forum. You can find it on Google.
