The version posted above by bradfordian is almost exactly what she sings on the Hedy West album. There are a few minor changes (including the transposition he made deliberately), and it's definitely little Ella. (latter pronounced as Eller)

500 MILES

If you miss the train I'm on, you will know that I am gone -
You can hear the whistle blow a hundred miles.
  Hundred miles, a hundred miles, a hundred miles, a hundred miles.
  You can hear the whistle blow a hundred miles.

If my honey said so, I'd railroad no more,
I'd sidetrack my engine and go home.
  And go home, and go home, and go home and go home.
  I'd sidetrack my engine and go home.

Lord, I'm one, Lord, I'm two, Lord, I'm three, Lord, I'm four,
Lord, I'm five hundred miles away from home.
  Away from home, away from home, away from home, away from home,
  Lord, I'm five hundred miles away from home.

I told my little Ella, just as plain as I could tell her
That she'd better come along and go with me.
  Go with me, go with me, go with me, go with me;
  She'd better come along and go with me.

My clothes are all worm and my shoes are all torn,
Lord, I can't make a livin' this a-way.
  This a-way, this a-way, this a-way, this a-way,
  Lord, I can't make a livin' this a-way.

If this train runs on right, I'll be home tomorrow night,
For I'm coming down the line on Number Nine.
  Number Nine, Number Nine, Number Nine, Number Nine,
  For I'm coming down the line on Number Nine.

Not a shirt on my back, not a penny to my name,
Lord, I can't go back home this a-way.
  This a-way, this a-way, this a-way, this a-way
  Lord I can't go back home this away.

If you miss the train I'm on, You will know that I am gone
You can hear the whistle blow a hundred miles.
  Hundred miles, a hundred miles, a hundred miles, a hundred miles.
  You can hear the whistle blow a hundred miles.
