The Orange County Line began in 1990 as the Orange County Commuter, an Amtrak-operated service between Los Angeles and San Juan Capistrano. The Orange County Commuter made a single weekday round-trip; departing San Juan Capistrano in the morning and returning in the evening.Amtrak conveyed the route to Metrolink on March 28, 1994, becoming the "Orange County Line" and Metrolink's fifth route. Service is provided seven days a week, with 19 trains on weekdays, and six 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.
