In readings the advice is to do a small layout, before attempting a room size. Makes sense. I have an HCD started, but also want to hook up a turnout with the electronics. The intention for any turnouts not manually controlled is to have both fascia control and computer control. Here's a start on a test turnout. I'm using PECO electrofrog Code 55 and modifying the wiring, not without anxiety. Tam Valley electronics: servo driver Octopus III with stationary decoder add on Servo switch with snap switch red/green fascia controller I've drawn their fascia controller mount in Sketchup and printed it on a Makerbot Replicator II, the yellow parts in the photo. I'm using 1" or deeper foam glued to 1/4" birch plywood, so using same for this. I'm waiting for a resistance solder unit to do the soldering on the bottom of the turnout. I've done power feeds with a regular soldering pencil but for this delicate wiring I bit the bullet on the resistance solder unit.
