OkScout, you said:

"Honey, you can't love one,
Honey, you can't love one,
You can't love one and still be fun
So I'm leaving on the midnight train
La-dee-dah, oh boy, toot, toot!"

That's similar to the old-time song, Ridin' on that New River Train".

Ridin' on that New River Train,
Ridin' on that New River Train,
My sweetheart said, said she'd rather see me dead
Than ridin' on that New River Train.

Darlin', you can't love one.
Darlin', you can't love one.
You can't love one and have any fun!
Ridin' on that New River Train."

The New River is an actual river, in Tennessee I think. Seems to me I've heard an historical explanation about why it was so undesirable to be seen ridin' on that train, but I disremember it now.
