The Capitol Corridor is a 168-mile (275 km) 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 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.

During fiscal year 2011 the Capitol Corridor service carried over 1.7 million passengers, an 8.1% increase over FY2010. Revenue in FY2011 was $25,720,252, a 12.5% increase over FY2010. It is the fourth busiest Amtrak route by ridership, surpassed only by the Northeast Regional, Acela Express, and Pacific Surfliner.

The Capitol Corridor is used by commuters between the Sacramento area and the Bay Area as an alternative to driving on congested Interstate 80. Monthly passes and discounted trip tickets are available. Many politicians, lobbyists, and aides live in the Bay Area and commute to their jobs in Sacramento, while workers in the Oakland, San Francisco, and Silicon Valley employment centers take the Capitol Corridor trains from their less expensive homes in Solano County and the Sacramento metropolitan area.

John Griffith "Jack" London (born John Griffith Chaney, January 12, 1876 – November 22, 1916) was an American author, journalist, and social activist. He was a pioneer in the then-burgeoning world of commercial magazine fiction and was one of the first fiction writers to obtain worldwide celebrity and a large fortune from his fiction alone. He is best remembered as the author of Call of the Wild and White Fang, both set in the Klondike Gold Rush, as well as the short stories "To Build a Fire", "An Odyssey of the North", and "Love of Life".^{[citation needed]} He also wrote of the South Pacific in such stories as "The Pearls of Parlay" and "The Heathen", and of the San Francisco Bay area in The Sea Wolf.

London was a passionate advocate of unionization, socialism, and the rights of workers and wrote several powerful works dealing with these topics such as his dystopian novel, The Iron Heel and his non-fiction exposé, The People of the Abyss.

Jack London's mother, Flora Wellman, was the fifth and youngest child of Pennsylvania Canal builder Marshall Wellman and his first wife, Eleanor Garrett Jones. Marshall Wellman was a great-great-great-grandson of Puritan Thomas Wellman. Flora left Ohio and moved to the Pacific coast when her father remarried after her mother died. In San Francisco, Flora worked as a music teacher and spiritualist claiming to channel the spirit of an Indian chief.
