San Clemente’s already battered coastal rail line is getting another overnight rescue mission after high tides and large swells damaged track protection, forcing a temporary closure and fresh emergency work this week. Crews are scrambling to shore up the route before another round of high tides arrives.
According to ABC7 Los Angeles, the Orange County Transportation Authority and Metrolink are repairing two sections between the San Clemente Pier and the San Diego County line. Crews are replacing damaged rock protection, adding several truckloads of ballast and working overnight from 10:30 p.m. to 5 a.m. through Wednesday.
Another Surf Assault On South Orange County Tracks
Recent swell activity damaged coastal infrastructure and eroded the rail line’s protective materials, while salt water also caused communication interference affecting other trains, ABC7 reported. The repairs are limited to the existing track footprint, but forecasts calling for more high tides later this week are keeping crews on a tight schedule.
The immediate problem is part of a much larger vulnerability along the coast. The Orange County Transportation Authority says the San Clemente segment is part of the 351-mile LOSSAN corridor, the nation’s second-busiest passenger rail route, which also carries more than $1 billion in freight annually.
Rocks Are The Quick Fix While Officials Study Bigger Moves
OCTA’s emergency program covers four vulnerable areas and combines rock reinforcement with sand nourishment. Its project plans call for roughly 540,000 cubic yards of sand, with riprap used where needed to stabilize slopes and shield the tracks from wave action.
The broader Coastal Rail Resiliency Study is examining ways to protect about seven miles of railroad for the next 10 to 30 years. A separate state-led effort could consider moving the rail line inland, but officials say that kind of solution would take decades and cost billions of dollars, according to ABC7.
San Clemente’s Rail Emergency Has Become A Recurring Headache
This week’s damage is the latest in a string of disruptions along the scenic but increasingly fragile route. A previous landslide shutdown kept Metrolink and Pacific Surfliner trains out of San Clemente for nearly two months in early 2024, after debris and slope movement threatened the tracks.
For now, the strategy remains familiar: repair the rock, replace the ballast and hope the ocean gives the railroad a little breathing room. The long-term question is whether repeated emergency work can keep the line running—or merely postpone a much more expensive decision about where the tracks belong.
