The train hit a man and his dog on the tracks near Santa Fe and Ash around one o'clock Wednesday afternoon. Both were killed.
Amtrak officials say forty-seven people were on the train at the time. None of the passengers or crew members were hurt.
The train was heading south from Oakland to Bakersfield and was delayed for just over an hour because of the crash.
It's not clear yet why the man was walking on the tracks.
