SANTA CLARA — A motorist was killed when an Amtrak train collided with a vehicle along Lafayette Street on Friday morning, authorities said.

The collision was reported just after 10 a.m. along Lafayette south of Agnew Road, involving Capitol Corridor train 527 that originated in Sacramento and was bound for San Jose, according to Amtrak.

Amtrak spokeswoman Vernae Graham said a single vehicle with one occupant was involved in the collision.

Graham added that none of the 45 passengers and crew aboard the train were injured. The train was delayed by about 2½ hours as a result of the collision.

Union Pacific and Santa Clara police are investigating the collision, said Amtrak spokesman Marc Magliari.

Magliari urged pedestrians and motorists to exercise caution at railroad crossings.

“The advice is always the same: Do not cross the tracks until there is space on the other side,” Magliari said. “Do not stop on the tracks for any reason.”
