What you need to know about the runaway train that killed two people and injured eight more

A runaway train carrying passengers and a crew from China to Washington, D.C., derailed on Friday evening in the middle of the Virginia region, killing two people, injuring eight others and trapping hundreds of cars in a car wreck that left a trail of destruction in the path of emergency crews trying to rescue trapped passengers.

The incident happened about 11:30 p.m. in Loudoun County, Virginia.

The U.S. Coast Guard said the train’s speed of 80 miles per hour was “at a minimum” at the time of the derailment.

One of the passengers was killed and a second was hospitalized with minor injuries, according to the Coast Guard.

It was unclear whether the other passengers survived the wreck.

The train was traveling on a rural track about 1,000 feet above sea level.

The crash took place in a small rural area in the Potomac River valley, about 50 miles (80 kilometers) northwest of Washington, which has a population of about 17,000 people.

At least two cars had rolled down a hillside on a small residential street, but none of them had overturned.

The cause of the crash remains under investigation, officials said.

No one was immediately injured in the crash.

An investigation by the U.A.E. National Transportation Safety Board is continuing.
