Hi, Olddude -
As far as I can tell, the song is not in the New Lost City Ramblers Songbook. It is on the 1958 self-titled album by the New Lost City Ramblers.

Here are the lyrics from the album notes:

RAILROADING AND GAMBLING

What your mama done told you
Six months ago,
Keep on your hat and coat,
Be ready to go.

(CHORUS)
Railroading and gambling,
Picking up chits for a madman,
Lord, Lord, Lord.


Been in the State House
Been in that yard
Been in the coalhouse
Worked least of all.
(CHORUS)

Said that preacher,
Golly ain't it a sin,
Johnny get your britches
'Cause here comes the wind.

Out on the railroad
Down on the track.
Lost all my money,
No way to get back.

John - banjo and vocal

The liner notes say only that Uncle Dave Macon recorded the song.
