CSX St.Louis line ATCS

Why is it that it is not possible to make a ATCS for the St.Louis line?
Charge your camera battery BEFORE you go to the tracks.

The way the signal system communicates does not work with ATCS. As I understand it, it will never get ATCS as CSX has moved on to a new system.

I was pretty sure that route wasn't ATCS.
And you are right, CSX has gone to a satellite based comm system now, so their new stuff won't be ATCS.
That and some other projects use the signal system through the rails.

Which, in this case, you'll know when there's a broken rail too.

Uhh...with the conventional signal systems, the tracks all carry a low voltage current through them at all times.  The wheels 'shunt' the circuit, which is how the signal system operates.  A broken rail now causes a break in the circuit, and puts the signals to 'red' (and its associated meaning).  As long as you have a signal system operating, you'll always know when you have a broken rail, at least one that breaks the entire rail.  Still doesn't pick up when chunks of rail break off, but doesn't result in a complete break of the rail.  Always fun hitting a missing chunk of rail at 50 mph.

BEFORE THE DAYS OF ATCS BEING THE NORM FOR SIGNAL CONTROL, THE RAILS WERE THE IMPORTANT PART OF HTE SYSTEM. THE ERIE WAS ALL BATTERY POWERED SYMAPHORES FROM HUNTINGTON TO LIMA. NO WELDED RAIL, AT THE JOINTS WAS A CABLE CALLED A BOND THAT CARRIED THE CURRENT FROM ONE RAIL TO THE NEXT. WE WOULD HAVE TO WALK THE SECTION EVERY 30 DAYS TO TEST THESE BONDS TO MAKE SURE THEY WERE NOT READY OT FAIL. TEST CONSISTED OF A STEEL ROD TO PRY ON THE BOND AND A LOT OF LEGWORK, MY HOW THINGS HAVE CHANGED.

The only big change is the loss of codeline in many cases.
Electracode via the rail, or via satallite or via radio waves.

No worries, there are still bonded joints a many, granted not as many as there use to be!

I WORKED WIH A MAINTAINER AT KINGSLAND WHO KNOW HOW TO WORK THE SYSTEM, HE WENT TO WORK ON THE ERIE IN 1939. HE WOULD NEVER LET ME FIX A BOND I THOUGHT WAS GOING TO FAIL, HIS RESPONSE WAS IT WILL BE OKAY WE WILL GET IT NEXT TIME.  WITHIN A WEEK WE WOULD GET A CALL OUT MIDDLE OF THE NIGHT, SIGNAL DOWN. WE BOTH LIVED CLOSE BY SO WE WOULD HAVE IT FIXED WITHIN AN HOUR. AND THEN GET 4HRS O/T CALLOUT. HE WAS A VERY COLORFUL PERSON.
