I've got the chance at my LHS to purchase an Atlas B23-7 with the decoder installed at a good price. Problem is, my layout is DC. I plan on my next layout to operate DCC, switching my DC diesels over to DCC as budget permits. My question is, can I operate that DCC diesel on my DC track without doing damage to the decoder? I was told there would be an AC to DC problem with capacitors on the decoder board which might make the DCC diesel work erratically at times on my DC layout...is this true? I thought that by getting a DCC now, I'd at least have one to run on the new DCC layout when I start it (which might be pretty soon). But until then, I was hoping to run it a while on my DC track. Also, can you run a DCC diesel on a DC track with other DC-only diesels without doing damage? I'm sure this type of question has been asked before - but I was unable to find the thread. Thanks guys.
