The Surf Line is a railroad line that runs from San Diego north to Orange County along California's Pacific Coast. It was so named because much of the line is near the Pacific Ocean, within less than 100 ft (30 m) in some places. The tracks are now owned by the Southern California Regional Rail Authority and the North County Transit District, and hosts Metrolink's Orange County Line and Inland Empire–Orange County Line, the San Diego Coaster, and Amtrak Pacific Surfliner passenger trains. The BNSF Railway operates freight over the line using trackage rights.
