Again Thank you so so much it was a very helpful video and I now fully understand

Absolutely outstanding! So I have a station with auto stop I had no idea they were using similar technology how outstanding! I am so grateful for this video and you taking the time to make it! This will help so many of us. I cheated with me signal because it is missing the bimetallic strip and mechanism. So I ordered the blinking red bulb and wired it in direct. I was able to achieve blinking however will keep my eyes open for the proper mechanism. I am watching a for parts signal due to the bad casting so hopefully I can win that auction and get im this one going the correct way. 😊 I love leaving them as original as possible.
