@Tracker John posted:The locos he mentions will work on conventional control that's the best configuration to start. With the exception of DCC which uses DC current, all of the systems mentioned operate on AC current and can be used on the same layout.
This is incorrect, DCC is actually modulated AC power to the track. And DCC locomotives can run AC conventionally, depending on the decoder. I use the ESU LokSound L and XL decoders which can run conventionally on AC and DC.
I don't understand why DCC continues to be mentioned as a command control system in the 3 rail world. Neither MTH PS2 or Lionel TMCC or Legacy can run on track powered by DCC.
The OP's question had DCC in it, hence why it is part of this conversation. But how he interchanged it with DCS, it could be he got them mixed up. But I do run DCC at home on my 3 rail layout. It's out there as has been shown by other posters to this thread.
You cannot operate AC powered 3 rail locomotives on DCC. That includes all non-command (conventional) locomotives, TMCC, Legacy, or DCS.
This is not 100% correct. Most Legacy locomotives can run on DCC powered track. But due to some issues I do not recommend it.
I realize this is the 3-rail traditional toy trains section but I must modify a statement above about Legacy and DCC. First, DCC track power is not DC. Second, almost all the S Gauge Legacy engines will run on DCC powered track in DCC mode, but not with a full set of features. The tradeoff Lionel made for DCC functionality is the S Gauge Legacy engines do not have Bluetooth capability.
This is why I stated in O in my 1st comment, because I know Legacy S has DCC, which I wise they'd bring to O instead of Bluetooth.
