Very interesting. Why is that a low flashing yellow indication, yet the turnout is not open for the diverging route?

I will have to pass on all technical questions to Roy... this is way over my head 
. The software programming involved in building the signal and switch control panel continues to absolutely boggle my mind!! I'll add photos to my original post.
Where did you get those signals?, they look pretty neat.

Slow to stop... proceed slow speed passing signal and through turnouts, preparing to stop at the next signal. ( yes I had to look that one up 
) I must say I don't think I've ever run across this signal with the switch set for the normal route. On the other hand we had a sub ( Halton sub in the Toronto area ) that was sometimes single track .double track,, all over the place with high speed turnouts.
Anyway I love the signals and hope your train crews obey the rules.... . Wouldn't it be nice to have a CTC panel with a crew member designated as a train dispatcher setting up signals. If not the signals could revert to Automatic block signals,,,, Fun stuff.

In the U.S. "Flashing Yellow" is "Approach Medium", and rarely if ever used on a lower quadrant signal, especially with the turnout NOT open. Since the turnout is NOT open, a "Flashing Yellow" should have been on the top position, thus indicating that the next signal would be "Yellow" (Approach). A "Flashing Yellow" on a single signal head could also mean that the next signal could be a "Diverging" indication.
Roy this is amazing looking work my friend.

Locally (Cleveland Ohio) NS uses 3 head signals. Track speed (top) is RYG. Medium speed (middle) is fixed red. Slow speed (bottom) is RYG.
They use a sequence of: red over red over flashing yellow (slow approach)/ red over red over yellow (restricting)/yellow over red over red (approach)/ green (clear block). This allows high speed freight to be well separated.
Flashing yellow on the top target is advanced approach (train 2 blocks ahead) indicating that the next aspect will be approach. Not necessarily a diverging aspect.
Also red over red over green is used as a diverging aspect (slow clear into the intermodal yard e.g.)
Each railroad has their idiosyncrasies. The Employee timetable is the final word.

Wow! Leave it to you guys to push the envelope, FANTASTIC. Good pictures of Roy and George.
Is this your layout,or are you building it for a customer?
Beautiful work !!
LOU N,
Your explanation is informative, however it still does not explain why there is a "flashing yellow" on the lower signal head, with the turnout not open, in the video posted above.
Another Great job by the DYNAMIC DUO, ROY & GEORGE!!!!! Holy WIRES & WATTS!!!!!

I watched the last picture which was a video, and at one point the video shows someone on the floor poking wires. So maybe not everything was fully hooked up and boards didn't "know" the turnouts position yet to correctly indicate on the signal.
I use Custom Signal stuff and until I got everything hooked up and debugged protypically, my poor layout engineers were surely perplexed with weird signal indications that weren't in any NORAC books!

HOT WATER,
I was just indicating that in the real world (specifically CP110 NS Cleveland Line) one can see a flashing yellow on the slow target in a thru traffic mode. It happens when the dispatcher has the line in FLEET for multiple westbounds.
Not sure who designed the aspects this way. Like I said, slow target green is the diverging mode at this control point.

RRMAN is correct this project is no where near complete or programed. Look's interesting but I'm glad someone else is doing it..Good luck guys.

Hi Jim,
This is a layout for one of our customers who recently retired from CSX. Man... you'd think our studio was a part time lab for Texas Instruments! Oh my the brain power involved in getting all these signals to work and talk with the programming... not to even mention the incredible wiring going on underneath... Roy, Mike, and George are doing a smash up job!!! I keep rolling my eyes and saying... "this is a TOY TRAIN layout guys... it's not for REAL trains!" lol. That's my way of encouraging them when a challenge is encountered
Happy Easter/Passover Weekend!

This post was to show off the first.... very first signal that was wired and turned on. I'll post again and it'll blow your mind when all the signals are working and the scenic landscaping is complete!
