Surf Line

The Surf Line was a railroad line that ran from San Diego north to Orange County along California's Pacific Coast. It was so named because much of the line was near the Pacific Ocean, within less than 100 feet (30 m) in 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.

Construction of the Surf Line between Los Angeles and San Diego began on October 12, 1880, with the organization of the California Southern Railroad Company. On January 2, 1882, the California Southern commenced passenger and freight service between National City and Fallbrook Junction, just north of Oceanside. From Oceanside the line turned northeast for a winding route through the Temecula Canyon, and was finished on August 21, 1882.
