Good to hear from you MattW and thanks for that information. You are correct that CSX has downgraded the Georgia line Class 1 Railroad status to Class 2 from Lithonia to Comack Georgia. From Atlanta to Redan it retains Class 1 status, how that is possible I do not know. All container freight unit trains are now being moved from Atlanta to Savannah via the Mansfield subdivision. It appears that Cindy Sandborn, VP at CSX did not want to spend the money for PTC upgrades on the Georgia line Augusta to Lithonia and this has relegated the traffic to essentially local movements only. The line now seems to have LESS traffic on it than the Norfolk Southern 'S' Line between Atlanta to Macon; that particular line was TWC just like the Georgia Line albeit less control signals. It will be interesting to see if CSX will keep the control signals operational from Lithonia to Augusta now with so much less traffic. Of course, the Georgia Line remains a relief line in cases of emergency,.
Since this thread is about PTC in TWC territory - there is more TWC territory on CSX than just the Georgia Sub.
PTC has been installed and made operational on both the Short Line Sub and the Ohio River Sub and this is 'totally dark' territory without any form of ABS signaling. PTC was made operational during the Summer of 2016. The territory runs between Grafton, WV and Huntington, WV
