WASHINGTON — A 13-year-old girl has died after she was hit by a Virginia Railway Express train on the Manassas Line Wednesday afternoon.

The teen, whose name has not yet been released, was hit by a VRE train between mile marker 28 and 29 near Clifton, Virginia, around 3 p.m. Fairfax County police said the girl had been hiking with two family members: a 13-year-old boy and a 22-year-old man.

The teens were walking on the bridge at Bull Run between Clifton and Manassas. When a train approached, the boy was able to get out of the way, but the girl was hit, according to police.

Police say she was a student at Lake Braddock Secondary School.

VRE planned to resume regular service on the Manassas Line Thursday.

The VRE incident happened less than a day after two CSX workers were fatally struck by an Amtrak train just north of Union Station. The fatal collision on Tuesday night led to suspended service, delays and disruptions on both the Amtrak and MARC lines into Wednesday morning.
