A tractor-trailer struck the side of a passenger train in Nevada earlier Friday, according to officials with the Amtrak railroad.

In a statement Amtrak said the incident occurred about 2:20 p.m. EDT. at a railroad crossing east of Reno.

The National Transportation Safety Board said federal investigators were en route from Washington Friday evening.

The Associated Press reported that two people — the truck driver and a person on the train — were killed. An undetermined number of people were being transported to hospitals, the report said.

The train, the westbound California Zephyr, was carrying about 204 passengers and 14 crew members while en route from Chicago to Emeryville, Calif., Amtrak said.

Officials from Amtrak and Union Pacific, which owns the tracks, were en route to the scene.

“We are saddened by any injury and appreciate the emergency response by local and state agencies,” Amtrak said in its statement.  

Amtrak issued the following information line number for people with questions about families and friends who may have been aboard the Zephyr: 800-523-9101.
