Ah, we've both been doing the same thing, yes there's plenty of info on there. Getting an accent you can understand is sometimes the hardest part. One of the most confusing things about DCC, is though wiring follows DC polarity conventions to a certain amount, it is actually a different wavelength and is the reason DCC decodered engines can run on the same track in different directions and he talks about track 1 and track 2 rather than positive and negative. Short circuits still happen as well as other similarities i.e. reversing circuits, but in the case of turnouts as you can see, it's different. The Peco Electrofrog as it's produced for DC, will short on DCC. Just don't ask me why.
