The Virginia Railway Express’s Manassas Line tracks are shut down south of Burke Centre while police investigate a death this morning.

A Fairfax County police spokeswoman said that the investigation, which according to a dispatcher began about 11 a.m., would likely last through the end of the evening rush hour.

Officer Shelley Broderick said that the body of a female was found in the woods of Hemlock Park. Police are not releasing the woman’s identity yet.

“There is no sign of foul play,” she said.

Buses will bring riders who need to travel past Burke Centre to the three remaining stops on the Manassas Line. When the 327 train arrived at Burke Centre about 4:40 p.m., the railway said that two buses were available to ferry riders, and six more were on their way to the station.

The VRE said that passengers who plan to have others pick them up at the station may want to disembark at an earlier stop, since Burke Centre’s parking lot will be unusually crowded today.

Trains that were south of Burke Centre when police asked the VRE to shut down the tracks at about 2:30 p.m. could not return to the beginning of the line at Union Station. Therefore,VRE canceled the trains that normally depart from Union Station at 4:25 and 6:10. The 5:05, 5:30, and 6:50 trains from Union Station were scheduled to depart as usual.

VRE riders can also use their tickets or passes to take the Metro today.

The VRE and police officers in Fairfax City and Fairfax County declined to provide information about the death that caused the tracks to close. A county police dispatcher said that “it’s going to be a long-running incident,” and a VRE spokesman said “it’s a safe bet that it’ll go through rush hour.”
