It would be one thing if they were just going to Fresno. There are three major cities in the Central Valley: Bakersfield, Fresno and Sacramento. You get Bakersfield for free; Sacramento is north of SF and has existing commuter rail. Fresno is big enough to justify a stop; it has room to grow, too. You could put a stop that's ten miles outside of Fresno, and you don't have to cut through the city too much. That's what they do with airports. Throw in a LRT while you're at it.
But the plan also calls for Tulare and Madera to have stops. Now you're doing three times the work for a 20-40% increase in the population served. Then they want a line to Sacramento that goes through Merced and Visalia At this point it looks silly. Fresno is larger than Tulare, Madera, Merced and Visalia combined. Stockton already has the Altamont Commuter Express line to San Jose.
Having HSR stops inside cities is one of the things that make it far better than flying for certain distances. Put the station outside the city and you're killing a lot of your benefits...
Ten miles from Fresno might be too far. I just picked a distance out of thin air.
But when you have a minor stop, it's less important to build the perfect configuration. Even if you have to go outside of Fresno to get on the train, you're still in downtown SF or LA when you get off. And the traffic in Fresno is not as bad as the traffic in SF. And the flights from Fresno airport are probably not as cheap, since it's a lower-volume airport (capex per flight is larger), so you have more of a cost advantage.
So I'm pointing out a false dilemma. You don't have to choose between downtown Fresno and no Fresno. You can have a worse-is-better Fresno without sacrificing the goals of HSR for the really big cities.
