Hi all, I'm making a small layout out of my Delta starter set. I have three delta locomotives and a few analog ones. Some of the analog loks are very old and I'd like to keep them original, but I do like running the delta trains with the controller.

How can I wire up both systems so I can put a couple analog loks on the tracks with signals and blocks, then if I want, pick them up off the tracks and put the delta loks on the tracks and switch over to the Delta controller?

I can probably make up a simple switching array that feeds the trafo either into the delta module or to the track, but I'm wondering if there's a more elegant solution.

In the spirit of using as much from my starter set as I can, I am retaining the blue transformer and I bought a matching blue Delta unit on ebay.

To me, the logical solution would be to install a flip switch which would completely isolate one power source and would only allow operation of one system at a time. This would mean that both red/yellow and brown would be selected from one transformer at a time.
There would be no possibility of both being connected as the flip switch would have to be completely at one end for analog and completely at the other end for delta.
