Reply to "3 Rail DCC O vs 2 Rail DCC O"

It is correct that there is only one basic DCC control system format. What varies is the origin of the DCC control signal and the method by which the DCC decoder control signal is handed over to the loco. Traditional track signal based DCC layouts use various trackside encoders. More recently, wireless DCC systems have come on board which create the DCC control signal in the PC module onboard the loco. For a modeler considering DCC, this might be a more convenient approach as it avoids any modifications to the track power arrangement.
