An Amtrak engineering worker was struck and killed by an Amtrak train about a half-mile north of the Bowie State University MARC station Tuesday morning.
The accident happened near the west end of the university campus.
Crews from Prince George's County Fire/EMS responded to the call at about 9 a.m., according to Mark Brady, a department spokesman.
The train was taking passengers along Amtrak's 86 route, part of its Northeast Corridor service. It operates Monday through Friday between Richmond, Virginia, and South Station in Boston.

The Bowie State station is, however, part of the MARC commuter rail route, known as the Penn Line that runs between Washington, D.C.'s Union Station and Perryville in the northeast corner of Maryland.
At the time of the incident, there were 251 passengers were on board the train. Those passengers were transferred to train 182 after a delay of about 90 minutes, Amtrak officials said.
There were no reported injuries to passengers or crew members. The tracks were re-opened at about 3 p.m., with some train passengers experiencing residual delays, acccording to Amtrak officials.
The National Transportation Safety Board confirmed the victim was an Amtrak employee and sent a pair of investigators to survey the scene.
"We are deeply saddened by the death of an Amtrak engineering employee this morning in Bowie, Maryland. We are working closely with the FRA (Federal Railroad Administration) and NTSB to thoroughly investigate the details of this incident," Amtrak spokeswoman Beth K. Toll said in a statement.
"We request you please respect the privacy of the family and co-workers during this difficult time."
