The 351-mile Los Angeles – San Diego – San Luis Obispo Rail Corridor (LOSSAN Corridor) travels through a six-county coastal region in Southern California and is the second busiest intercity passenger rail corridor in the United States. The LOSSAN Corridor service includes 41 stations and more than 150 daily passenger trains, which includes the Amtrak Pacific Surfliner as well as Metrolink and COASTER commuter trains.
The LOSSAN Rail Corridor Agency is a joint powers authority comprised of rail owners, operators, and planning agencies along the entire LOSSAN rail corridor. The LOSSAN Agency is governed by an 11-member Board of Directors composed of elected officials representing the counties of San Diego, Orange, Los Angeles, Ventura, Santa Barbara and San Luis Obispo. Management responsibility for the Pacific Surfliner service was assumed by the LOSSAN Agency in July 2015, following the execution of an interagency transfer agreement with the state of California. Amtrak is the contracted operator of the Pacific Surfliner service. The Orange County Transportation Authority (OCTA) provides management and administrative support to the LOSSAN Agency.
