WTF is this accounting logic? This isn't Japan, Brightline doesn't own any of the land around their stations. Various local governments in Florida own many of the stations and they invested several billion of taxpayer dollars to help build them. Orlando alone spent $680 million for their station though they got reimbursed by the feds for some of that. Miami spent $77 million on the Aventura station and Biden gave them a $34 million grant to offer a commuter pass.
Brightline is going bankrupt, but makes enough money to keep the lights on if they don't have to pay for their capital expenses, so the train could stick around if the company is sold for pennies on the dollar. Of course, in that scenario all the investors and bondholders are screwed and good luck funding any capital improvements in the future.
HSR was made obsolete with the invention of the airplane over 100 years ago.
