Houston - 4th largest U.S. city, not exactly "3rd tier" (2000 Census)
Phoenix - 6th largest U.S. city
San Diego - 7th largest U.S. city
Dallas - 8th largest U.S. city
San Jose - 11th largest U.S. city
San Francisco - 13th largest U.S. city
Note also that we're talking about one corridor within a larger Los Angeles rail network.
BART : Muni light rail = Purple Line extension : Expo Line
There's need and justification for both, given limited transit funds: heavy rail for the highest-density corridors, light rail for others. LA's Red Line is the only new U.S. heavy rail system started in the last thirty years.
You sure about "100% grade separation everywhere"? Green Line photo at Boston University. Also see Jon Bell's Philadelphia Subway-Surface photos.
Overland, Centinela, Sepulveda, and Farmdale are gated crossings with full preemption.
