Two years ago an Amtrak Capitol Corridor passenger train outside Sacramento jolted so violently that passengers thought it would derail.
The engineer had mistakenly sped at double the limit through a track crossover. Coffees, laptops and some bodies went flying. Two people were slightly injured. Ultimately, two train operators were disciplined. But the human-error incident left several passengers saying they wondered if rail officials were really focused on safety.
Now, corridor train officials say, an incident like that is unlikely to happen again.
As of this fall, all trains on the 170-mile Capitol Corridor system have been equipped with a computer system that will take control of the train from the engineer if the engineer fails to heed speed or other warnings.
