Metrolink and Amtrak train services could be suspended through December during repairs due to shifting ground beneath a stretch of seaside track in Southern California. Service between Orange and San Diego counties was halted Sept. 30 after a recent storm surge caused waves that shifted the tracks near the coastal community of San Clemente. Initially, officials said service would be restored in November. But the Los Angeles Times reports Wednesday that the work could keep passenger trains off the tracks through the end of the year.
