Sure, but it would cost a few billion. For just modestly sized stretch of rail and a couple of stations and trains. Waymo is of course not cheap but they can do a lot with a few billion. Rail just isn't cheap. Privately funded rail tracks are basically not a thing in most countries. Just too expensive to be interesting to normal investors. Especially if they are looking for ROI measured in years rather than decades/centuries. Governments spend on rail because of the wider economic effects it has on their economies. Not because exploiting rail roads is particularly lucrative or even profitable.
