This is the Amtrak Pacific Surfliner With SC-44 Charger. The Pacific Surfliner is a 350-mile (560 km) passenger train service serving the communities on the coast of Southern California between San Diego and San Luis Obispo. The route is the successor of the San Diegan, a Los Angeles-San Diego service operated since 1938 by the Santa Fe Railway. It had been one of the Santa Fe's premier routes until Amtrak took over operations in 1971. Initially there were three daily trips, but the schedule was expanded to six round trips during the 1970s with funding from the state of California. In 1988 the service was extended to Santa Barbara to provide the Central Coast with an additional train to Los Angeles, followed in 1995 with one trip a day going all the way to San Luis Obispo. To better reflect the route's extent, it was renamed the Pacific Surfliner in 2000. The route is named after the Surf Line, which now comprises the route's busiest section from Los Angeles to San Diego. A stop at Old Town Transit Center was added in 2004. Stops at Orange and Laguna Niguel/Mission Viejo were added in 2007 but dropped in 2012. On October 7, 2013, stops were added at Coaster stations at Carlsbad Village, Carlsbad Poinsettia, Encinitas and Sorrento Valley. The Carlsbad Poinsettia and Encinitas stops were dropped on October 9, 2017 due to low ridership. The Carlsbad Village and Sorrento Valley stops were dropped on October 8, 2018 due to changes with the cross-ticketing arrangement with Coaster. The Pacific Surfliner runs on track owned by several private railroads and public agencies Union Pacific Railroad: San Luis Obispo – Moorpark (Coast Line), Southern California Regional Rail Authority: Moorpark – Los Angeles, BNSF Railway: Los Angeles – Fullerton, Southern California Regional Rail Authority: Fullerton – Orange County/San Diego County line, North County Transit District: Orange County/San Diego County line – San Diego.
