Amtrak Train No. 14, the Coast Starlight, left Los Angeles at 10:10 a.m. Saturday and was scheduled to arrive in Vancouver at about 12:30 a.m. Sunday, spokeswoman Christina Leeds said.
At about 9 p.m., two miles north of Fremont, however, the two wheels of the front truck on the lead locomotive derailed from the track, Leeds said.
Fourteen crew members and 154 passengers were aboard the train at the time of the derailment, but no one was injured, she said.
Leeds said the train left Fremont at about 12:30 a.m., and is scheduled to arrive in Vancouver about four hours later than its original destination.
The cause of the derailment is under investigation.
