Is it possible to create a layout which with the throw of a simple switch can go from DC control to DCC control and back again?Mine does. I have two oval circuits with several terminal branches. The power feeds from the track have crocodile clips at the end so that when (or more accurately if) I want to use analogue dc I connect the crocodile clips to the terminals on the analogue dc controller. When I go back to DCC I connect the two negative clips together and the two positive clips together and connect them to the DCC power feed. Takes seconds.
I also have the option to have one section analogue and DCC should I wish as the two circuits are isolated due to their analogue origins.
My accessories at this point still comes from the AC output from the analogue controller but when I get my new DCC system and more dosh I will ultimately have them operated from the new system.
Where control of your accessories lies and if you have isolate sections and electrofrog pointsWhat are the constraints when contemplating a dual purpose layout?
Defeats the purpose of having DCC. One of the big selling features of DCC is that you don't have to mess around with all the extensive wiring of isolated sections.Is it better to opt for totally isolated separate layouts within a layout?
