@Mark Boyce, Mark, thanks for the kind words and I’ll bet your laughing at my wiring, and when I look at the pictures I can see why. Although lt looks like a lot of colored spaghetti with masking tape with ID numbers. There are plans to clean this mess up. Also you can see 1/2 of my ASC’s, BPC’s that control 41 turnouts and 19 blocks. This allows me and friends to walk around the layout and turn in any block or train or switches from the Cab 1L, Cab 2 hand held remotes, or I-phones?… My plans this winter is to change up some blocks, add new switch machines to some of the 20 year old Atlas switches, also replace some older DZ1000 machines. When Captain Will Porath, @will2926 was here a few months ago, we set up blocks for going to different levels, up and down the helixes, and it makes a huge difference as some routes have 10 or more switches, using Cab 2, hit the route desired then Fire….. Today I just adjusted power to the different accessories. Happy Railroading Everyone
