Dual purpose DC/DCC layout design and construction

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?


This subject may be of interest to a lot of members and visitors who are contemplating DCC but don't want to have to chip all their locos and especially the older collectables that they may have that may not work so well with DCC.

What are the constraints when contemplating a dual purpose layout?


Is it better to opt for totally isolated seperate layouts within a layout?


I would guess that with Hornby keeping it simple and using the track as the "bus" then it would be equally simple with such a set up to incorporate a switch that immedietely converts to whole layout back to DC control. You then remove all your DCC chipped locos and have a play with your non chipped locos.

Happy modelling

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 points

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.
