Of the many versions, that by Jessie James is one of the most unusual. For comparison, here are a couple of verses from other versions.

From Furry Lewis:
Lord, some people said Mister Casey couldn't run,
Let me tell you what Mister Casey done;
He left Memphis, was a quarter to nine,
Got to Newport News, it was dinner time;
It was dinner time,
Got to Newport News, it was dinner time.
It uses a partial chorus,
On the road again,
I'm a natural born eastman, on the road again.

Possibly Cornelius Steen.
On a Sunday mornin' it begin to rain,
Around the curve he spied a passenger train;
On the pilot lay poor Jimmie Jones,
Dead and gone, oh, he's dead and gone;
He's a good old porter but he's dead and gone.

Versions like that sung by Jesse James show the hand of the Black railroad worker; they are quite different from the standard versions.
Verses above from Norm Cohen, "Long Steel Rail."
