The end of the week sees all the three switches wired, and PC-controllable.
But let's start where we left off - the second switch on the PT segment. A couple of tests were done to ensure everything works ok at this point, and the BR 66 worked flawlessly (first photo). Next the place for the hole in the foam board for the third switch was marked, I heated up the soldering gun, started cutting along the markings....and soon 
stopped. The thing is this last switch does not need to be "sunk"; both its starting and ending point are well above the ground foam level. So instead of carving the whole switch ballast contour, adding the 13 mm pieces where the old squares were, and glueing on top the 30 mm thick board, so the required height could be met, a portion of the ramp where the height was lower was used (4 mm lower actually - since that is the distance from the bottom of the tie to the bottom of the switch ballast piece).
Next on the list was a minimal wiring - connecting all the return conductors (red on the 86112 Tillig switch motor), and the other 2 wires (pink/yellow) to a Phidget 1017 board. The return conductors were all connected to the center casette (a future post will detail the wiring), using a Viessmann connector (if you're looking for something like this - the code for the yellow one is 6842), while the Phidget and its corresponding wires were placed in a new casette that was dug, right below the front track in the second photo. Also new holes were carved in the foam board for easier access to the wires.

The outer track was cut to size using the Xuron tool, and Tillig connectors were used when needed to hold the rails together.
What needs to be done next: solder feeders to the end of each track segment (the Viessmann 85501 connectors are good, but they will fail eventually regarding electrical conductivity), polarization of the frogs (the frog of the Tillig switches is not "live" - but the 86112 motor comes with wires especially for this), insulation between the diverging track of the switch pair (Tillig 85502 connectors), cut holes in the base wooden board for later access to the switch motors (and the really important thing - find a way to hide it), connect the wires for the feedback indication (which way the switch is set), airbrush the ties on all 3 switches, and any remaining track strips (6 strips are already done since a couple of months ago), and mount the last remaining piece of the ramp up to the station.
