Here is the version I recall hearing as a kid:

In the Blue Ridge mountains of Virginny,
Lived a cow by a railroad track.
She was a good old cow with eyes so fine,
But you can't expect a cow to read a railroad sign,
So she stood in the middle of the track,
And the train came and hit her in the back.
You'll find her bones in the mountains of Virginny,
And her spine on the Lonesome Pine.
