In way of an update on current operations, the former ACL line between Thomasville and Albany, GA was sold some years ago to Mr. Pete Clausen, the owner of the (fill in the name) & Ohio systems of railroads, in this case the Gulf & Ohio. Several years ago, Mr. Clausen sold the Gulf & Ohio to USA Railnet, who began operations on several lines out of the Albany, GA area as the Georgia - Florida Railnet, with the reporting marks GFRR. These lines include the:
The above-mentioned line between Thomasville and Albany, GA;
The former South GA/NS line between Adel, GA and Perry, FL (with CSX having trackage rights between Quitman, GA and Perry, FL for shared service to a large paper mill about 4 miles SE of Perry, FL. (so the predecessor Seaboard Coast Line could abandon most of the old Perry Cutoff Line (between Perry and Metcalf, GA);
The former Georgia & Florida RR/NS line between Valdosta and Nashville, GA; and
The Albany - Sylvester, GA portion of the former ACL line between Albany and Waycross, GA.
The GA - FL Railnet's operating base and headquarters is the former ACL's Albany Yard in Albany, GA.
Noteworthy, the GA - FL has acquired four former Canadian National wide-cab GP40-2WL units, and have repainted them in a green with tangerine stripe color scheme. Nice looking! These were some of the original wide-cab, or North American comfort cab units, the forerunners of the wide cab styles of EMD and GE.
Regarding the cat litter, the only places that I am aware of that produce cat litter in the Thomasville, GA area are several processors on the former Seaboard Air Line (CSX) line between Bainbridge and Columbus, GA. These processors are located about 20 miles north of Bainbridge. This line is currently operated by the Georgia Southwestern RR. Cars from these processors would most likely have a Thomasville routing label, as Thomasville is the nearest yard point.
Keep 'em rolling!
