"Railroad Runs thru Georgia" is an old-time breakdown in A Major. It is played in AEae fiddle tuning. The parts are played AABB. The tune is crooked: the A part has nine measures.
The melody was in the repertoire of Oklahoma's Pottawatomie County Collins family, whose latter 20th century representative, fiddler Earl Collins, recorded several albums. Older members of the family (such as W.S. Collins) contributed to Marion Thede's book.
Lyrics from The Fiddle Book:
Railroad runs through Georgia,
Railroad and a canal.
If it hadn't been for Liza Jane
There never would've been no hell.

(Sung to the second part of the melody)
There never would've been no hell, boys,
There never would've been no hell;
There never would've been no hell, boys,
There never would've been no hell.
 (Sung to the second part of the melody)
Wrap up your troubles in your mind, boys,
Wrap up your troubles in your mind;
Wrap up your troubles in your mind, boys,
Wrap up your troubles in your mind.
The banjo tablature is by John Letscher.
