Two train staffers were left injured after a train hit a semi-truck that was sitting on the tracks. The incident occurred in Chattanooga, Tennessee, on Tuesday evening, with heavy delays expected to last throughout Wednesday.
Three locomotives and at least 10 railroad cars were derailed while waiting for a traffic light to change in Collegedale.
The freight train hit a truck carrying a 134-foot (41-meter) concrete truss bridge beam that was intended to be used for a reconstruction project, according to Tennessee Department of Transportation spokesperson Rae Anne Bradley.
Two Norfolk Southern Train employees were hospitalized with minor injuries, said the Hamilton County Office of Emergency Management.
Photos showed the black locomotive and carriages lopsided alongside the tracks, while other photos showed smashed rebar and glass.
The truck was stopped on the railroad tracks waiting for the light to turn green, according to the Tri-Community Volunteer Fire Department.
Officials said when the crossing arms were activated the driver attempted to clear the tracks but was unsuccessful.
The crossing was blocked by the crash and an investigation is underway, and several agencies responded to the collision including a team to clean up hazardous materials like leaking diesel fuel from the locomotives.
Posting on Twitter, the Chattanooga Fire Department said at 7.59pm local time (12.59am on Wednesday GMT): “Chattanooga Fire is assisting with a train derailment in Collegedale.
