I had assumed that if they were going to the trouble of digging a multi-mile tunnel they would use it as a test bed for key hyperloop technologies. It's obviously not going to make any money, so it seems like it's more of a proof of concept to help pitch bigger projects to cities in the future. But as-is, this has lower passenger capacity per minute and more failure points than a fast lightrail system.
