Authorities evacuated Union Station, the main train terminal in Washington, D.C., on Sunday afternoon due to a chemical odor from an equipment closet, according to a spokesman for the D.C. Fire and Emergency Medical Services Department.
The odor, described as smelling like sulfur or natural gas, was believed to come from an area where batteries and other equipment is stored, said fire department spokesman Peter Piringer.
A hazardous materials response team was on the scene, Piringer said. No injuries were reported, but authorities decided to evacuate the entire station as a precaution.
An Amtrak spokesman said all rail traffic in and out of the station was temporarily suspended due to the evacuation. Subway service continued to operate, but trains were not stopping at Union Station, according to the Washington Metro Area Transit Authority.
