Hello again all, The Foam board is in the process of being layed as I type this post . The question I have for this thread is, Do any fellow model railroaders have a mimic board of their layout setup , so they can tell where the trains are the layout? I had wanted to bury glass reed switches into the foam, under the track, at relative locations and have a magnet attached to the bottom of the loco. Once the reed switch is activated, a LED will light on the mimic board. Does anyone have any ideas regarding this question? It's all part of the master plan before i get too carried away. I love alot of bells and whistles and lights.
