@aaronpk Sigh. The bit about the tracks depressed me. The Talgo trains Amtrak Cascades uses are designed to run just as fast as the Siemens trains Brightline uses. But track conditions don't allow it.
I mean, all the amenities you describe are very nice, but having trains that fast would be life-changing for of lot of people in the PNW, even if you had to dine on stale crackers.
@aaronpk If tracks allowed the trains to run at full speed, it would be an 90-minute trip.
