Hi Alex,
well, I have spent most of this weekend reading and re-reading your journey into making the most incredible layout that I have ever seen (or expected to see��). Before I forget, thank you for documenting this entire process. I am totally impressed. How I got started on this thread, and the reason for my post, is that I am stuck trying to make my control panel for a 16x20 layout. I have tried to learn about relays and the specs I need them to be via the Internet but to no avail. I came across your relay modules and was wondering if you could tell me how to build them including the exact type of relay you used, the specs and why? I have about 10 track blocks on two main lines and a number of sidings along with 17 turnouts (so far). The track wiring consists of 12 gauge main lines with 16 gauge drops. I obviously don't want to take 12 gauge to the control panel, thus the desire to use relays with a much smaller wire to the toggle switches on my control panel. I will be using DCS.
Thank you. If you would prefer not to reply on this thread, my email address is mike_mccormick444@verizon.net. I really appreciate your help.
