Yes. DCC puts an AC power signal(ok, it's not technically AC, it's a digital square wave signal) in the track. I can adjust my system, usually I put about 16.5-17 Volts out of my booster, I have an adustable 24V power supply, so I turn it down for O scale. That's the input voltage, that actually track voltage, measured RMS voltage, is probably around 16V. Remember, the DCC command signals are low voltage digital waves combined with the power signal, sent out on the rails in conjunction with the the power wave, as if they were signal wires. Everything ignores them on the rails except for the address of the engine receiving the signal. LionChief is an over air system, uses Bluetooth I believe. They don't use the rails for train control. All you need for LionChief is a 16v+ DC or AC voltage on the track, which DCC provides. I've run 2 DCC engines and 1 LionChief many times in my smaller layout. The LionChief engines simply filter the power to DC, this what they actually use to power the trains. EDIT: This post was edited to clarify some of the things I mentioned, ie. square wave digital instead of AC, etc. DCC is AC-Like, but not AC.
