Amtrak train 719, a westbound San Joaquin heading fro Bakersfield to Oakland, speeds through Blanco, just south of Corcoran, California, on February 20, 2018. These Amtrak trains operate with equipment owned by the state of California - in this case, a Siemens SC-44 "Charger" locomotive (CDTX 2106), five passenger cars (four ex-NJ Transit Arrow I "California Comet" coaches and one Horizon food service car), and a former Amtrak F40PH locomotive converted into a non-powered control unit.
From one train each way in 1973 between Bakersfield and Oakland when it started up, this line as expanded to six trips daily; four to Oakland and two to Sacramento.
