Less than three days after a 175-car train derailment blocked freight and commuter rail service early this week, shipping company CSX says it finished clean-up of the mess on Tuesday night.

“All rail cars involved in the incident have been removed from the site, soil impacted by the sodium hydroxide release has been excavated and replaced with clean fill, and the rail infrastructure has been restored,” CSX said in a statement on Wednesday afternoon. “The first CSX freight train operated through the area at approximately 9:30 p.m. Tuesday, May 3.”

Sixteen of the trains cars derailed around 6:40 a.m. on Sunday near Rhode Island Avenue and Ninth Street NE. First-responders were able to contain chemical spills without having to evacuate residents.

No one was injured in the derailment and officials said no environmental impacts have been found. D.C. Del. Eleanor Holmes Norton is set to meet today with the Federal Railroad Administration, which is investigating the incident, to discuss it. “Unfortunately, Sunday’s CSX derailment is emblematic of the nation’s crumbling infrastructure, and we can expect to see more incidents unless we get serious about having a 21st-century transportation infrastructure,” she said in a statement on Monday. “This derailment is a wakeup call that should teach us about preventing future hazmat rail car derailments.”

Officials have not yet indicated what caused the derailment.
