Train orders and timetable schedules were phased out in late '80's/early '90's in favor of track warrant control. CEA

I wonder where Southern's first CTC installation was? Jack Wyatt

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

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? Scott Chatfield

I just thought I would point out that groups.io has a built in database feature that can be directly accessed from the groups.io web page. So if you read these posts on your email, you would never

Connecting control points and track circuits from along a route to CTC machines was not a trivial (or inexpensive) project. The Southern's C&S Dept. was innovative when they adapted the signaling (E&M

Odd to imagine TT&TO still being used so late.

CTC wasn't common on Western Lines. Southern liked to make sure the ROI was there. CEA

Ike, I would be happy to help with the F cards. Just assign the lower numbered ones to me, principally the wood cars, since that is what I have been working on already. Dave

One other thing….. Having some form of lookup process will help is a big way. A single Card List can include different car series (note the three pairs of columns). Those series may/may not be from

Would any SRHA members be interested in helping to catalog SRHA’s drawings by entering the pages on the different card lists into a spreadsheet? When that is done, we will link the pages from the

Does anyone know when the Southern's Atlanta-Birmingham line converted to CTC?

Hey Ike, I did not get an attachment. Dave -- Owner, Cumberland Model Engineeringwww.CumberlandModelEngineering.com (865) 333-5712Pastor, St. Paul Presbyterian

Attached is one of the very few linens in the SRHA collection that does not have a title block or date. It is obviously a box car but the odd strapping on the sides of the car suggests it is a wood

I’ve attached two examples from Card Index ("F-Card”) F-13 that Dave mentioned. Virtually all of the F-Cards for Southern railway freight cars and passenger cars (P-Cards) are in the SRHA
