Heavy rain severely eroded soil under train tracks in northern San Diego, canceling Amtrak and commuter rail service at least through Christmas weekend.
The soil is completely gone under sections running 50 to 75 feet, leaving the track hanging in midair.
The transit district has ordered 2,000 tons of gravel to reinforce the track.
Wiggins says Amtrak has suspended service between Oceanside and San Diego. The transit district canceled service on its Coaster commuter line, which carries about 6,000 passengers on weekdays. Freight service is also suspended.
