Norm Cohen's book "Long Steel Rail, The Railroad in American Folksong" (1981 Univ of Illinois Press, and according to another recent thread here about to be reprinted) devotes about 20 pages to the Casey Jones saga and some of the subsequent lyrics that are posted above. I do not know to what extent Cohen's analysis and descriptions of the historical events may agree or differ with those at the linked site. Interestingly Cohen did not include a complete set of the lyrics to what is probably the best known of the Casey Jones songs, but used the Furry Lewis version as his primary source.
