locked Re: CTC on the Atlanta-Bham line

What really got Southern into CTC big time was the elimination of double-track on parts of the CNO&TO and then the Mainline between Atlanta GA and Alexandria VA 

I do wonder if its first installation was a short stretch somewhere which may be viewed as an extended interlocking.

Here’s an ATS/ATC map from 1947….

Now for a gripe! I have mentioned how much material there is in the SRHA archives many times. Actually, it’s pretty useless if people will not go to Chattanooga to see what’s there. I realize we are in the “Google” era and many people will not travel farther than their PC keyboards.

Anyone is welcome...….Flame me off line if you wish….

I realize now I should asked when TT&TO was done away with, rather than when CTC was implemented.

Ah okay, I'd forgotten about ABS. The ancient TT&TO system was starting to disappear on many railroads by the 40s.

The H Line south of Atlanta wasn't converted to CTC until, what, 1988?
