This 10 Billion in bond money approved by the voters builds the first leg, from Anaheim and Disneyland Resort to LA Union Station, and then up the San Joaquin Valley to San Jose and San Fran's Transbay Terminal downtown. This will be the main trunk line for the system, and will get it started.
Further bond requests would add in the feeder lines and extensions from Anaheim to Irvine, from LA to Riverside and San Diego, and from San Jose to Oakland and Sacramento.
The Feds still need to chip in their share to the tune of another 10 Billion, and the stations are going to need to involve private investment. In Anaheim the Orange County Transit Authority has already drafted a proposal, blessed by President Bush's Secretary of Transportation during her visit this past summer, for a inter-modal station called ARTIC. Currently the Anaheim station near Disneyland is very busy with several dozen passenger trains per day from the Amtrak Surfliners and the Metrolink commuter trains. The ARTIC station would beef up the Amtrak and Metrolink facilities, be a major hub for the CaHighSpeed trains, and also link in with a proposed monorail extension from Disneyland. The Anaheim and Orange County proposal developed over the past few years under the assumption that High Speed Rail would eventually get built in SoCal, is being used as a model for other cities and counties who now have to come up with station proposals for the high speed trains.
