The National Transportation Safety Board (NTSB) has sent a full go-team to Crozet, VA to investigate yesterday’s grade-crossing accident involving an Amtrak passenger train and a truck.

The chartered train, which was carrying Republican lawmakers headed to a retreat in West Virginia, collided with what news sources say was a garbage truck. One person associated with the truck was killed and another critically injured. Amtrak said in a statement that two of the train’s crew members and three passengers were taken to a local hospital with minor injuries.

Amtrak said the truck was on the track at the time of the collision.

As investigator-in-charge, NTSB senior highway safety investigator Pete Kotowski will lead a multi-disciplinary team with expertise in human performance, highway factors, survival factors, vehicle factors, truck operations, train operations and grade crossing signals. The NTSB’s Office of Railroad, Pipeline and Hazardous Materials Investigations and the Office of Research and Engineering are also sending investigators.
