The Southeast High Speed Rail Corridor (SEHSR) is a passenger rail transportation project in the Southern United States to extend high-speed passenger rail services from Washington, D.C. south through Richmond, Petersburg with a spur to Norfolk (the Hampton Roads region) in Virginia through Raleigh, Durham, Greensboro and south to Charlotte in North Carolina and connect with the existing high-speed rail corridor from D.C. to Boston, Massachusetts known as the Northeast Corridor. Since first established in 1992, the U.S. Department of Transportation (USDOT) has extended the corridor to Atlanta, Georgia and Macon, Georgia; Greenville, South Carolina; Columbia, South Carolina; Jacksonville, Florida; and Birmingham, Alabama.
