Lullaby Lyrics

I've been looking for the words to an old lullaby my mother sang to me. I know there were more verses, but nobody can seem to remember them. What I remember is this:
The car was coming around the bend, goodnight my lover, goodnight.
It's loaded down with hard working men, goodnight my lover, goodnight.

Can't be too old if it has a car in it.
Thanks so much! Would love to sing it to my babies.
