The two small cities it will connect are actually on opposite ends of some bigger cities, meaning they will be connected to those larger job and commerce centers. This is how German high speed rail developed.
"If he meant Borden and Corcoran, the two rural end points of the line, they have a combined population somewhere north of 25,000. But the main stations along this first stretch of the system won't be in Borden and Corcoran. They'll be in Fresno and Hanford and, eventually, Bakersfield. Metropolitan Fresno alone (942,000) dwarfs Anaheim (354,000).
Population numbers aren't the point, though, because the short rural section is just a slow start to something large and complicated - which is the right way to build high-speed rail, if you look at the systems in Europe."
