LOS ANGELES – Beginning Monday, Aug. 10, through Friday, Aug. 14, Metrolink will temporarily suspend Orange County Line service between the Laguna Niguel/Mission Viejo and Oceanside stations due to anticipated high tides. During this period, Orange County Line trains will only operate between Los Angeles and Laguna Niguel/Mission Viejo. Alternate bus transportation will not be provided. At this time, weekend service is not expected to be impacted.

These temporary adjustments are designed to preserve the overall reliability of Metrolink’s system after similar high-tide conditions late last month caused significant delays that extended beyond the affected corridor. Originating and terminating Orange County Line trains at the Laguna Niguel/Mission Viejo Station will help minimize broader disruptions, including potential cancellations, providing customers with more predictable service and a better travel experience.

Amtrak Pacific Surfliner and freight providers will operate normally as long as it remains safe to do so. Metrolink crews have been proactively preparing the track infrastructure in South Orange County this week, laying additional ballast and rip rap to protect against water erosion. Qualified personnel will continue to monitor coastal tracks during high tides, increasing inspections ahead of each passenger train approaching the area. Equipment and materials are also staged nearby to ensure necessary repairs can be completed as quickly and efficiently as possible.
