Where's the funding going to come from? USA has no money for infrastructure. MTA is struggling in NYC. Seattle's light rail is going to be completed in 2041+ and is being paid through a regressive car tab tax. I think it's a pipe dream that rail or transit will ever be improved other than very modestly in the USA.
Plenty of money and land for pipelines though https://i.imgur.com/IdwIHQB.gif
