A rail car carrying wood caught fire just after noon Sunday in Southwest Washington.
Firefighters from the D.C. Fire Department extinguished the flames and moved the car to a rail yard in Virginia to unload its contents.
Officials said the fire began sometime before the car was stopped at Fourth Street and Virginia Avenue SW between the L’Enfant Plaza and Federal Center Southwest Metro stations, but they have not identified a cause.
There were no injuries.
Three businesses in Anne Arundel County were held up at gunpoint within a few hours Friday night, possibly by the same robbers, authorities said.
The robberies occurred at an automotive service station in Millersville about 7 p.m., at a fast food restaurant in Glen Burnie about 9 p.m. and at a doughnut store in Pasadena at 9:20 p.m., the county police said.
One robber carried out the first holdup and two were involved in the others, police said.
However, the descriptions of the robbers in the three incidents were roughly similar. Ski masks were worn in two and dark clothing in all three.
At least one robber in all the incidents was described as about 5 feet 7 to 5 feet 9, with a stocky build. In all cases, police said the robbers carried black handguns.
