> That’s a function of the train speed. If the train traveled at 300 mph, then LA<->SF becomes faster than Brightline’s 180 mile LA to Vegas route, which looks like it will average 100 mph.

Even with the speed, you would have to do LA <-> SF as the crow flies. California HSR Phase 1 is 520 mi.

On the other hand, LA <-> LV is effectively flat, at least from where the Brightline leaves in Palmdale. The difference between the two projects is pretty stark.
