 This is a demo of the Logic Rail Fuzi Pro product. It's a board you put on the rails and it gives you a 10 minute burn just like a real prototype Fuzi. What's great about the Logic Rail product is that you can set the 10 minute time to fit any fast clock ratio from 1 to 1 to 16 to 1. In this demo, I set the Fuzi Pro to burn at 8 to 1, which is the speed I use on my Cisco line. And it's actually just over 1 real minute in length. A railroad flare or Fuzi is time to burn for 10 minutes. And a Fuzi is typically dropped behind a train to ensure a safe spacing is maintained. The following train encounters a burning Fuzi. It is not to pass until the Fuzi burns out. Fuzis made specifically for railroad use have a sharp steel spike at one end, which is used to embed the Fuzi upright in a wooden railroad tie. The Logic Rail Fuzi starts out burning bright, then flickers realistically. And once the burn time has expired, the Fuzi will slowly fade out, as we can see it doing right here. Once the board goes dark, to remind you to remove the board from the rails, a yellow LED flashes periodically. To reset the board for another burn, just remove it from the rails. It's all set and ready for a new burn. You can find this product at logicrailtech.com.
