Thank you, Darrell, Gene, Tom, Rod, Randy!
I actually have the Z-Stuff turnout controllers and the push buttons are temporarily placed on the front of the layout frame. The plan is to have about 3 local panels with the button lights showing. My trouble is that I don't remember to throw all the switches I want when I want to change routes. I do have the capability to setup routes in the DCS AIU, but haven't done it yet. I still think I want to have a visual. The one problem with this layout is that the switches on the upper level for the passing track and the tops of the two inclines are near the backdrop, and at 30 inches in depth at 50 inches above the floor, I have trouble reaching if I do have a derailment. I have had them with certain cars because 3 of those switches were in the last batch I bought. After installing and wiring, I discovered the plastic frog is a smidgen higher than the rails. That doesn't bother my engines, but does bother lighter lit cars having pickup rollers. I hope my solution is to shave the plastic frog down on them. The trouble is, I don't want to remove them from the layout, so it could be a painful job. I could try the Dremel, but will have to watch I don't melt the plastic. I'm not very handy with it.
Rod, you didn't side track at all. You presented your solution to the problem I brought up. Your indicator lights are really nice looking, and yes you could put them anywhere. That's a very slick design.
