Orange County Line

The Orange County Line began on April 30, 1990 as the Orange County Commuter, an Amtrak-operated service between Los Angeles and San Juan Capistrano funded by the Orange County Transportation Authority.[4][5] The Orange County Commuter made a single weekday round-trip, departing San Juan Capistrano in the morning and returning in the evening.[6] Between July and December 1993 during the Orange County Commuter's final months, both the Commerce and Orange Transportation Center stations opened. Amtrak conveyed the route to Metrolink on March 28, 1994, becoming the "Orange County Line" and Metrolink's fifth route.[7][8] Service expanded to eight trips in 1995.[9]

In October 2005, the Orange County Transportation Authority announced that it would increase service on the Orange County Line, running trains twenty hours daily, seven days a week every 30 minutes. The first part of the additional service was implemented in June 2006 with Saturday service, and July 2006 with Sunday service. The plan has drawn criticism as many Metrolink stations are located beyond walking distance from important destinations such as Disneyland and the adjacent Anaheim Convention Center, Knott's Berry Farm, and the Irvine Spectrum. Funds for new rolling stock and track improvements were allocated from the voter-approved Measure M half-cent sales tax, while critics had advocated using the money for bus operations or other transit service instead. To address some of these issues, OCTA operates a series of Stationlink shuttle routes that connect Metrolink stations in Orange County to nearby destinations.

As of 2019 service is provided seven days a week, with 29 trains on weekdays, and 8 on weekends. The Amtrak Pacific Surfliner supplements Orange County Line service by providing limited stop service along the corridor and more service during mid-days, nights and weekends.

While the Orange County Line shares trackage with Amtrak's Pacific Surfliner trains, its northernmost stations (from Los Angeles to Fullerton, excluding Commerce) are shared with the 91 Line and nearly all of its other stations with the IEOC line (from Orange to Oceanside).

The Orange County Line runs on the BNSF Railway's Southern Transcon track between Los Angeles and Fullerton, under a shared-right-of-way agreement. Several stations, most notably the ones in downtown Fullerton and Santa Ana, are renovated Spanish Colonial Revival depots originally built by the Atchison, Topeka and Santa Fe Railway. Sections of the line between Santa Ana and Oceanside allow for 90-mile-per-hour (140 km/h) operating speeds.[1]

Under Amtrak operation the Orange County Commuter stopped at the following stations: Los Angeles, Commerce, Fullerton, Anaheim–Stadium, Orange, Santa Ana, Irvine, and San Juan Capistrano.[10] With the Metrolink takeover in 1994 the southern terminus moved to Oceanside and five infill stations were subsequently added:[11] San Clemente and Norwalk/Santa Fe Springs in 1995,[12][13] Tustin and Laguna Niguel/​Mission Viejo in 2002,[14][15] and Buena Park in 2007[16]
