At least 16 people were injured Wednesday when an Amtrak train collided with a truck blocking the tracks and partially derailed in Southern California, local officials said.

The driver of the truck was transported to a trauma center and another person was taken to a medical center with a "minor medical emergency," according to the Ventura County Fire Department. Fourteen others were transported from the scene with minor injuries, it said in a tweet.

The department said the other passengers of the Coast Starlight train appeared uninjured.

Train No. 14 was traveling from Los Angeles to Seattle at about 11:15 a.m. PT when it struck the vehicle obstructing the tracks in Moorpark, California, about 50 miles northwest of Los Angeles, the rail line said in a statement.

"The train derailed as a result of the impact but remained upright. Amtrak is working with customers to make alternate travel arrangements," Amtrak's statement said.

There were approximately 198 passengers and 13 crew members on board who were evacuated from the train, Amtrak said.

Fire and emergency medical crews have cleared the scene, the fire department said. Passengers were taken to a reunification center where they could contact family members.

Amtrak said it will investigate the incident in coordination with local authorities.
