Model Railroading > Bold infrastructure on the Texas & Gulf with tri-color signals

The Texas & Gulf has embarked on a infrastructure improvement, a signal installation program
with three color signals patterned after those still in use on the UP Corsicana Subdivision, an 
ex-Cotton Belt Route in East Texas.

Four of these were built and installed recently, protecting about 60 ft. of upper deck trackage.
Logic is also patterned after that on the Cotton Belt with yellow LED lamp lit when no
trains present (pic 1),  green LED lit when warrant issued for forward movement (pic 2), and red
LED when either a train passes the signal or train approaching the opposite direction.

The signals will also protect the ballast train whenever it arrives, if it ever arrives at all.

I'm still waiting on a ballast train myself. I think it's due in December :-).

Signals are interesting. My entire mainline scales out to about a mile and a half so hard to justify much.

It's funny how once you have operated on a layout with operating signals it hooks you in. Same as operating a layout with full DCC and sound, hard to go back afterwards.

Truer words have not been spoken in the model,rr world.

Goodie, goodie.

So these signals display a green light when you have Track Warrent authority to proceed?  How does the signal know that?
