context: Passenger rail service is provided by Amtrak San Joaquins. The main passenger rail station is the recently renovated historic Santa Fe Railroad Depot in Downtown Fresno. The Bakersfield-Stockton mainlines of the Burlington Northern Santa Fe Railway and Union Pacific Railroad railroads cross in Fresno, and both railroads maintain railyards within the city; the San Joaquin Valley Railroad also operates former Southern Pacific branchlines heading west and south out of the city. The city of Fresno is planned to serve the future California High Speed Rail.
question: Who owns the California High Speed Rail?
