Pat Sky did a version of "Reuben's Train" on his first album way back in the 60s. His version has a variation in the way the verses are done. I took the part with the longer (more lines & repetition) and applied the "folk process" to create a new song to the tune that I called "J.J.'s Train." It's about a short-lived short track railroad built in my home county by entrepreneur JJ White in the early 20th century. Lasted only about 17 years. I had a Great Uncle who tried to catch a ride on one of the slow moving freights when he'd been drinking and he fell off and got such a hard blow to the head that he died within a couple of days. I wrote him into the song as well.
Don't have my lyrics handy to post but you can hear a rough recording of it on my ezFolk page (it's down the list near the end).
All the chords are built around major chords, root (starting) chord of G.
