Okay, I'm back with my resource material. According to my 1928 Railroad Atlas. Atmore is served by 2 railroads, the L&N (now CSX) running east-west and the Frisco (now BNSF) running north-south.
For track layouts try the respective historical societies. Also look for old topographical maps. If you can get to the Atmore library, ask if they have any Sanborn maps. The Sanborn maps would show track layouts plus the layouts of the industries served and possible industry names. Can't remember for sure about the names it has been a long time since I look at some Sanborn maps.
