June 28, 2016 was a momentous day. On that day, four years after the first rail was laid on the Cape Ann, the last of the temporary coffee-stirrer block marker flags was removed and tossed in the ditch. By the end of the day, there would be no more dark territory as the layout became fully signalized. This required the installation of 40+ signal masts and 2 signal bridges. All are controlled automatically as blocks are selected from the control panels and comparator circuits beneath the layout compare adjacent block assignments to light the correct aspect.
Signal masts are scratchbuilt from brass tubing, LEDs, ladder from plastic canvas, and bases from old computer keyboard keys. Details >> http://rickmillsproject.com/mrr/signals/signals.html
