On rail that you mentioned:  SKY TRAN
Whoever it was that posted this on Sky Tran has the answer, and it would only cost about $400M to do the entire 20 mile route.  It would cut the time from 60 mins one way to about 15 or 20 mins.  Much cheaper, looks far better, would cost far less ($400M compared to $10B+), and is a beautiful project.  Cheap, fast, efficient, and very low maintenance costs.  Of course, it wouldn't have any room for the graft and corruption that the cement train has already built into it (went from $3B to $10B in feigned ignorance, bad luck, incompetence, and hidden meetings).  This would end all of that and be 30 times cheaper.  Way Faster, cheaper, better.  NO STOPS between your destinations makes it far faster!!!  And no creepy, smelly people!  lol!  Enjoy!
Take a look at this yourselves, and thanks to whomever it was that sent it first in here...:
