Wiring up indicator lights are easy, but without any information about what operates your turnouts, telling you how to do it will take a book. I started to give instructions for all of the scenarios I could think of, but it was so long it was looking like war and peace and I had barely started. You need to tell us everything you can think of about how you operate your turnouts, what sort of control you are using, do you have a central control panel or is it walk around? Are you using manual switch control or switch machines and if electric switch machines, is it twin coil or slow motion stall or mootorized machines?
