This video will demonstrate how my Block Detector and Turnout Block/Sensor Turnout boards work to control my block signals on a demo layout. It also shows how my Flasher board and Solid state relay board works with my block detector board to control the LEDs on a railway crossing. The video shows how to wire up my Capacitor discharge board. The video will also show using block diagrams how to wire these boards up. At the end of the video I show how I built my home made Block Signals.
