I am working on a new layout and I am wondering how to do signal light placmants. I like to use a lot of track lights and have had Block lights at all my turnouts controlled by an Atlas #66 deluxe under table switch machine. The issue is I'm not sure if in reality there was all these block lights everywhere(14 on my layout). I would like to be more realistic with my signals. I have looked on line to find out how to place the lights but have been unsuccesful.
