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 the Amtrak California brand. It runs from the San Francisco Bay Area to Sacramento, roughly parallel to Interstate 80. One train a day continues through the eastern Sacramento suburbs to Auburn, in the foothills of the Sierra Nevada. The trains are administered by the Capitol Corridor Joint Powers Authority and managed by employees of Bay Area Rapid Transit. Capitol Corridor trains started in 1991.
