Chris brings home a good point. 9V is what it is, probably because of the
powered rails. No other LEGO Train system has that. However, I do beleive that
one day very soon (if not already) battery technology will allow more power than
can be safely delivered through AC or DC, and it will last much longer than you
would ever expect:

Chris's Bluetooth suggestion is a good one. It got me to thinking about another
possible problem with wireless control. At larger Train Shows, if the wireless
waves travel too far they could effect the wireless trains on surrounding
exhibits.
Perhaps the coded and encrypted Bluetooth technology would be better than RF in
more than just computer control. Bluetooth requires a manual synchronization
between the controller and receiver. This synchronization tells the Bluetooth
transmitter which receiver that you want to communicate with.
Does anyone know how many receivers can be synch'd to one Bluetooth transmitter?
Thanks,
Scott W.
