How to isolate inner and out loops with KW transformer
« on: January 05, 2021, 02:23:17 pm »
I have a simple 027 layout that has an inner loop and an outer loop linked by two switches from the outer loop to two switches on the inner loop.  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 ?

Thanks

Wherever the switches join to the inner loop is where you need to isolate them with fiber pins on the center rail.

Hi,

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