I can run one train thru both loops via the switches or run two trains (one inner, one outer) thru the A terminal of my KW transformer. It's a problem, since one goes faster than the other and will run off the track while the other (outer) is barely moving. Right now both loops are powered off the same terminal/control lever. So here's the question - I would like to run the inner loop and outer loop separately using the two separate controls on the KW 190W transformer. If I put fiber pins in the center rail of the "outer loop side" of the switches that allow entry into the inner loop, then wire the inner loop to the B terminal (outer loop on A) will I be able to control each loop separately ?

That's what I thought. I will give it a try. *****************************************************
