    Hello,

    Was hoping someone could steer me in the right direction. Am looking for signal info, drawings, details, diagrams, for modern signal systems used on the AT&SF/BNSF lines! Can anyone steer me to existing websites for info or sites of model manufaturers that sell this type of signal equipment?

    Also have another question. The single target signal. Does it have red and green, red, yellow and green, or red and yellow lights?

    I want to use some scratchbuilding techniques to make what I can't find. I have some micro and nano LEDs, just need to find some info.

    Any help would be Greatly Appreciated!

    Thanks in advance!

    It has one white light and 3 occulars (lenses) that move in front of the light. I know, picky picky, but you really can see the lenses moving when the light changes. Red is in the center, and is the default if the occular motor fails (for safety). Green and yellow are to each side. So, when the signal goes from green to yellow, the signal shows:

    green:dark:red:dark:yellow

    Of course, it's real fast, but you can see the change and it's very distinctive. I have a searchlight mechanism in the garage (OK, I'm weird, I know it!)
    :teeth:


    The latest BNSF signals are upside down traffic signals, and they are being put on the new OSHA required highway-style signal posts. In Orange County (LA), the new masts have the old searchlights on them! :w20z6q:
