Context: Florida is served by Amtrak, operating numerous lines throughout, connecting the state's largest cities to points north in the United States and Canada. The busiest Amtrak train stations in Florida in 2011 were: Sanford (259,944), Orlando (179,142), Tampa Union Station (140,785), Miami (94,556), and Jacksonville (74,733). Sanford, in Greater Orlando, is the southern terminus of the Auto Train, which originates at Lorton, Virginia, south of Washington, D.C.. Until 2005, Orlando was also the eastern terminus of the Sunset Limited, which travels across the southern United States via New Orleans, Houston, and San Antonio to its western terminus of Los Angeles. Florida is served by two additional Amtrak trains (the Silver Star and the Silver Meteor), which operate between New York City and Miami. Miami Central Station, the city's rapid transit, commuter rail, intercity rail, and bus hub, is under construction.
