Good morning,
Lionel and Williams by Bachmann are 3 rail AC powered O-gauge.
DCC is a square wave DC power for 2 rail operation. As far as I know there are incompatible.
Bachmann does make DCC equipment but I think they only make HO and N scales for DCC.
There is such a thing as 2 rail O-gauge but Lionel does not make it.
What kind of power and control system and track are you using?
If you can give us more information we will be glad to try to help you.
Louis
