The right way to do this is to create a 3-state agency to handle a triangle of HSR between LA/SD, Las Vegas, and Phoenix.
A line between Phoenix and Las Vegas could use the Phoenix-SoCal tracks past the Calfornia border, then travel due north parallel to US 95. Such an alignment would avoid having to cross the Colorado River at the Hoover Dam or any of the difficult spots to the south.
Much of the construction would be through a landscape like this:

Yes, much of the landscape is rural and desert, so construction costs should be lower. But where will the builders/contractors live during construction? How much will that add to the costs to build?
I keep repeating that HSR has a two to three hour sweet spot. Amtrak’s Acela Service between NY and DC takes 3 hours 10 minutes on average (225 rail miles), and NY to Boston takes 3 hours 50 minutes on average. It falls just short of that sweet spot, which is why Amtrak is willing to spend $Billions for a relatively small 10 minutes of time savings.
LA to LV by driving distance is 263 miles. LA to Victorville is 82 miles, Victorville to LV is 188 miles - yes the sum of the legs do not add up to the total.
For a train to make the LA-LV trip in 2 hours, it would have to average 132.5 mph.
For a train to make the LA-LV trip in 3 hours, it would have to average 88.3 mph.
LV to Phoenix driving distance is 297 miles.
For a train to make the trip in 2 hours, it would have to average 148.5 mph
For a train to make the trip in 3 hours, it would have to average 99 mph
LA to Phoenix driving distance is 373 miles.
For a train to make the trip in 2 hours, it would have to average 186.5 mph
For a train to make the trip in 3 hours, it would have to average 124.3 mph
Keep in mind that Acela trains between NY to DC average around 70 mph. Trains to LV will have the advantage of no stations between Victorville and Las Vegas, and could reach maximum speeds for about 188 miles, a fairly long time for HSR trains. So they should have higher average speeds than what Acela achieves on the NEC with even slower trains.
But I still do not see LA to Phoenix passengers choosing HSR over a jet plane in the numbers required to make it worthwhile.
