Hi everyone, I hope you can answer one fundamental question I can't seem to find the answer to anywhere. Having had a traditional HO system as a child, and now introducing my son to railway modelling, I've decided to go N gauge to save space and make a more interesting layout. I've had the chance to acquire an MRC Prodigy Advance DCC system, but I can't find out anywhere how I wire it up two run two circuits connected by a pair of points (Uk speak !) and some sidings running of both circuits. I can see lots of talk about wiring up return loops, but I can't fathon out how this applies to a couple of normal circuits. Is it possible to do all this with the DCC system I've got ? Also, does anyone know of any problems with using Kato Unitrack and DCC ? Thanks guys ! ( & gals !) Nigel.
