A CSX freight train derailed Friday in Southeast D.C., sending at least five cars toppling off of a bridge and into the Anacostia River.

The incident occurred around 3 p.m. The train was crossing a bridge in Anacostia Park just north of Pennsylvania Avenue when it derailed. Ten of the cars were damaged, at least five were in the water and several more were hanging off the bridge as of Friday afternoon, said Alan Etter, spokesman with the Department of Fire and Emergency Medical Services.
