• SAN FRANCISCO TO SAN JOSE — The board said using the existing Caltrain corridor and sharing track with the slower commuter trains was the only “realistic alternative” even though that approach would reduce the number of daily high-speed trains between the two cities. The board dropped the idea of creating a separate high-speed line in the Caltrain corridor or creating a high-speed line that would follow Highway 101.
• OAKLAND TO SAN JOSE — The board kept two potential routes for more study. One would follow the Union Pacific’s Hayward line and then use an aerial structure in the Interstate 880 median. The other would follow a series of UP lines.
• SYLMAR TO LOS ANGELES — One route kept for more study would generally follow the Metrolink-Union Pacific corridor to Union Station or a new station close by. The other would veer off that corridor at Burbank and follow Interstate 5 before going through a tunnel under Elysian Park to the Union Station area.
• LOS ANGELES TO MARCH AIR RESERVE BASE — One possible alignment would follow the Union Pacific corridor to Colton, then turn south along the Burlington Northern-Santa Fe corridor before following Interstate 215 to the base. The other would follow a different Union Pacific corridor through South El Monte before picking up the Colton corridor near the City of Industry.
• MARCH AIR RESERVE BASE TO MIRA LOMA — The board selected a “minimizing tunnels” option that would go through Murrieta, Temecula and Escondido along Interstate 15.
• MIRA LOMA TO SAN DIEGO — There are still four potential routes under study. One would follow Interstate 15, then turn west along Miramar Road to the Los Angeles-San Diego rail corridor and then to south along the corridor or another route to the Sante Fe depot. Another would follow Interstate 15, State Highway 163 and then tunnel under Balboa Park to the Santa Fe depot. A third would cut from Interstate 15 through Carroll Canyon to the Los Angeles-San Diego rail corridor and then turn south. The fourth would follow Interstate 15 and stop at Qualcomm Stadium.
• LOS ANGELES TO ANAHEIM — The board settled on two possible routes: Following the Los Angeles-San Diego rail corridor with a stop in Fullerton or a Union Pacific branch line,
• ANAHEIM TO SAN DIEGO — The route would follow the Los Angeles-San Diego rail line, but only slower diesel-powered trains with a top speed of 150 mph would be used south of Irvine because the coastal communities consider the wires needed for electric trains unsightly.
The board is scheduled to consider routes between San Jose and Merced, Sacramento and Bakersfield, and Bakersfield and Sylmar when it meets in January.
