The Associated Press is reporting that seven cars of a freight train have derailed over the Anacostia River.

No injuries have been reported. Six of the seven cars are in the river, and another is hanging off the trestle. Coal and some hydraulic fluid and oil ended up in the river, but the fire department says it’s been contained.

We’ll update again when we learn more.

UPDATE 4:45 p.m. Thanks to an anonymous reader who sent us this photo of the derailment, taken on their phone.

UPDATE 5:20 p.m. Better photos added. NBC4 is reporting that witnesses said they heard a loud explosion and then saw the cars plunge into the river. They said the train appeared to be traveling at a slow speed.
