|The Capitol Corridor is a 168-mile passenger train route operated by Amtrak in California. Because it is fully supported by the state, the Capitol Corridor operates under Amtrak California. It runs daily from the San Francisco Bay Area to Sacramento, roughly parallel to Interstate 80. One daily-scheduled train continues through the eastern Sacramento suburbs to Auburn, in the foothills of the Sierra Nevada. There are plans to increase train frequency throughout the route. The trains are administered by the Capitol Corridor Joint Powers Authority, with management provided by employees of Bay Area Rapid Transit. The Capitol Corridor has been in operation since 1991.
