Is anyone here interested in Train Signals and how they work?

ARGH!

(Stupid me - again)

At least I posted the sub-flow way back near the start.

Today I was getting curious on how to get it working better, and I stuffed up.

Ok, I'll get the sub-flow I posted and stick it back in.

News flash:
All the links inside the subflow aren't there.

Anyone have an idea why that is?
Unless I am missing something.

I'm kinda stuck now because I did such a good job of fixing it until it broke I don't seem able to get the original sub-flow back.
