Wikipedia: Not to be confused with Southern Pacific Railroad. The Southern Railway (reporting mark SOU) (also known as Southern Railway Company and now known as the Norfolk Southern Railway) was a class 1 railroad based in the Southern United States between 1894 and 1982, when it merged with the Norfolk & Western to form Norfolk Southern. The railroad was the product of nearly 150 predecessor lines that were combined, reorganized and recombined beginning in the 1830s, formally becoming the Southern Railway in 1894.[1]

At the end of 1971, the Southern operated 6,026 miles (9,698 km) of railroad, not including its Class I subsidiaries Alabama Great Southern (528 miles or 850 km); Central of Georgia (1729 miles); Savannah & Atlanta (167 miles); Cincinnati, New Orleans and Texas Pacific Railway (415 miles); Georgia Southern & Florida (454 miles); and twelve Class II subsidiaries. That year, the Southern itself reported 26,111 million net ton-miles of revenue freight and 110 million passenger-miles. Alabama Great Southern reported 3,854 million net ton-miles of revenue freight and 11 million passenger-miles; Central of Georgia 3,595 and 17; Savannah & Atlanta 140 and 0; Cincinnati, New Orleans and Texas Pacific Railway 4906 and 0.3; and Georgia Southern & Florida 1,431 and 0.3.

The railroad joined forces with the Norfolk and Western Railway (N&W) in 1980 to form the Norfolk Southern Corporation. The Norfolk Southern Corporation was created in response to the creation of the CSX Corporation (its rail system was later transformed to CSX Transportation in 1986). Southern and N&W continued as operating companies of Norfolk Southern until in 1982, when Norfolk Southern merged nearly all of N&W’s operations into Southern to form the Norfolk Southern Railway. The railroad has used that name since.
