At least, this was the feedback someone gave me yesterday at another LHS. I could run sound on a DC layout but not get the full range of sound -- at least I'd hear some chuffs and whistles.
Hi Rob,
I would argue the exact opposite - the smaller the layout, the better DCC is as a control system. There is one big assumption - that you want to run more than one locomotive at the same time.
For small layouts like yours, iit is undoubtedly easiest to have one electrical block for the whole thing, powered by a conventional DC power pack. You can get into sidings that can be turned on/off in order to "park" locos without adding too much complexity.
But if you want to actually move two locos at the same time in close proximity (and in different directions at different speeds
), DCC is pretty much the only way to do it. Sound is just a bonus...!
