Jim - Looks and sounds great! I have dealt mostly with DC Analog, but want to go to DCC. I beleive what I posted will work fine for either, with some small changes for DCC (mostly where the track power comes from). Your description of an automatic reversing module usage seems even simpler than my DC method, I am going to try both to see. I have copied your drawings and comments to a file for future use. If anyone else tries the DC Analog drawings, I would appreciate some feedback - good or bad. Everything we do is a learning experience. Thanks to all. |

Not sure about the drive current of the SMC-12 but if you are using 4 switch machines why not drive the other three of them with the DPDT switch in the first one. This would give you an effective 6PDT switch to use for the other functions at no cost. I am using a mechanical linkage to control all four sets of points so it is not an issue for me. The "wire" is 0.030 copper plated wire feed welding wire that solders very easily to a piece of rail for the "push rod".
