No.
If the putative investors come up with untold millions to reactivate creaky rail lines through the middle of nowhere, to serve almost nobody and pander to some unrealistic fantasies, then they can make an announcement when work is ready to begin.
I'm sure that Mister Richie Rich will spend his money however he likes. If he wants to micturate it into the dusty South Australian scrub, then that's his choice, and I wish him the very best best of luck.
Of course, that's if they choose not to spend their money on something more likely to make money. Like, oh, I don't know, magic beans, or using rainbows and puppy love to generate electricity.
Until then, let's not waste electrons on giving it attention. Or oxygen.
Cheers,
Matt
