Ol Reuben had wreck
And it broke Reuben's neck
But it never hurt a hair on my head

Ol Reuben's goin down the track
And he's got the throttle back
And the rails are a carryin him from home

Your 4th verse is comparable to a verse from John Hardy:
I've been to the East, and I been to the West
I've been this whole world around
I've been to the river and I've been baptized
Tomorrow be my buryin ground, Oh Lord
Tomorrow be my burying ground.
