The East Ventura station and layover facility are on the Santa Paula Branch Line. History The railway was originally constructed by the Southern Pacific Railroad as their Coast Line, connecting Los Angeles to San Francisco. The Montalvo Cutoff between Burbank and Ventura via the Simi Valley was built in 1904, bypassing the old line further to the north. Caltrans ran commuter rail service over the line very briefly in 1982 and 1983, but CalTrain was unsustainable due to a number of factors. In 1990 the Los Angeles County Transportation Commission, predecessor of Los Angeles County Metropolitan Transportation Authority, acquired a portion of the right of way between Los Angeles and Moorpark from Southern Pacific and transferred it to the newly formed Southern California Regional Rail Authority for commuter service. The line began operations in 1992 as one of Metrolink's original three routes, with service from Moorpark to Los Angeles Union Station in Downtown Los Angeles. Service was extended to Camarillo and Oxnard in 1994 after the Northridge earthquake, then to East Ventura in 2002. Because Amtrak trains operate on the same corridor all day, every day, Metrolink did not operate weekend service on the line. As part of a six-month trial program to determine demand, Metrolink added Saturday service on April 6, 2020. Permanent Saturday service started on May 29, 2021, with one round trip between LA Union Station and Moorpark. Service was extended to Ventura–East on August 9, 2021. Metrolink established a code sharing agreement with Amtrak, allowing all Metrolink passengers to ride select Pacific Surfliner trains with any ticket or pass, starting April 4, 2022. The code sharing agreement adds one more morning and early afternoon trip to Ventura, expanding midday and Saturday service, and establishing defacto Sunday service on the line.
