Here's one accredited to Roy Acuff, as played by Earl Scruggs and Doc Watson, as remembered by me (probably missing a verse:

Ref: It's a long steel rail and a short cross tie,
I'm on my way back home,
I'm on the train, the queen of the rails,
That streamlined cannonball.

A headlight beams out through the night,
The firebox flash you can see,
I ride the line it's the life that I love,
for it's home sweet home to me.

I can see the smile on the engineer's face,
Although he is old and he's gray,
In his heart he waits for the call
On the Streamlined cannonball.
