How could the high surf impacts on the coastal rail corridor affect San Diego?
San Diego rail service may face delays and cancellations due to coastal corridor damage The high surf has caused severe operational issues along the coastal rail corridor, including signal interference and track erosion near San Clemente. This has led to temporary closures and the cancellation of trains, such as two Pacific Surfliner trains between Los Angeles and San Diego. Because this corridor is San Diego's only railroad connection to Los Angeles and the rest of the United States, these disruptions directly impact the reliability and scheduling of rail service for the city.

How it reaches San Diego
-
High surf impacted the coastal rail corridor in Los Angeles, shorting out railroad communications systems south of the San Clemente Pier. Waves also eroded gravel ballast beneath the track, requiring emergency repairs. Metrolink experienced restricted speeds and flagging due to water intrusion, while Amtrak canceled two trains between Los Angeles and San Diego.
The full event1independent outlet -
The coastal corridor is the 351-mile LOSSAN corridor, which is San Diego’s only railroad connection to Los Angeles and the rest of the United States. Therefore, operational failures and delays on this corridor directly affect the ability of trains to reliably serve San Diego.

Why it matters
The coastal rail corridor is a critical piece of infrastructure for San Diego, serving as its sole railroad connection to the larger Los Angeles metropolitan area and the rest of the United States. Any disruption to this corridor, whether from high surf or other factors, immediately compromises the reliability of rail travel for residents and commuters in San Diego.
The ongoing nature of the high surf, which is expected to continue through Thursday, means that operational impacts are not isolated incidents. The long-term preservation of this low-lying track near San Clemente is a major concern, with planners considering options like rerouting miles of track away from the coastline in the future.
