The corridor has been closed multiple times in the past year as erosion and landslides put coastal rail infrastructure in jeopardy.

Passenger rail service resumes today in Southern California, where a landslide damaged tracks in late January, forcing rail agencies to suspend service on the popular line between Los Angeles and San Diego.
According to an article in Mass Transit, “The Orange County Transportation Authority (OCTA) worked in partnership with Metrolink to build a 200-foot-long wall at Mariposa Point to safely re-establish service on the track.” The project was funded by the California Transportation Commission. “In the past week, the construction team working at the San Clemente site finished the catchment wall and have continued to work on a more comprehensive drainage system and trenching along the rail right of way. The team also worked in coordination with the city of San Clemente to adjust a sewer access point.”
The rail segment between Los Angeles and San Diego has been plagued by closures caused by erosion threatening the stability of the tracks, but a patchwork of jurisdictions and ownership have hindered a comprehensive mitigation plan.
