Below is probably the railroad song referenced in the News & Observer previously; it was reportedly a "popular worksong sung by the Negroes employed with Federal Flood Relief money in 1916 to construct highways in the lower part of Marion County (South Carolina)." I feel the style of song also lends itself well to railroad work.

Gwine back to Weldon, gal (Whuck)
Gwine back to Weldon, gal (Whuck)
Gwine back to Weldon, gal (Whuck)
To work on the Weldon road.

Hello, Mamie! (Whuck)
Hello, Mamie! (Whuck)
Hello, Mamie! (Whuck)
Honey, God bless yo' soul.

Gwine back to Weldon, gal; (Whuck)
Gwine back to Weldon, gal; (Whuck)
Gwine back to Weldon, gal - (Whuck)
Work on the Weldon road.

Gwine to Cincinnati, gal; (Whuck)
Gwine to Cincinnati, gal; (Whuck)
Gwine to Cincinnati, gal - (Whuck)
Honey, where they pay you mo'.


Bring you mo' money, gal; (Whuck)
Bring you mo' money, gal; (Whuck)
Bring you mo' money, gal - (Whuck)
Honey, dan yo' lap kin hol'.

Captain and the walkin' boss, (Whuck)
Captain and the walkin' boss, (Whuck)
Captain and the walkin' boss (Whuck)
A-raisin' cain all day.
