Questions
Is HO the same as OO?
They run on the same track gauge, but OO models are built to a slightly larger scale, so the two look mismatched when run side by side.
Can I run DCC locomotives on a DC layout?
Many DCC decoders can run on DC, but you lose the DCC features. DC-only locomotives need a decoder installed before they will run properly on DCC.
