A 14-car Pan Am Railways freight train derailed in Lawrence Friday morning, officials said.
The Lawrence Fire Department responded when seven cargo cars and one locomotive went off the tracks shortly after 11 a.m., said Chad Nickerson, a Lawrence firefighter.
The eight cars that derailed were in the middle of the train. Four additional cars in the front and two locomotives in the back remained on the tracks.
Deputy Fire Chief John McInnis said the train derailed between the South Union Street overpass and the rail yard on Andover Street.
No one was injured, said McInnis.
The train cars were empty and there were “no hazardous material concerns,” he said.
The Haverhill commuter rail line was delayed for a short time, said Keolis Commuter Services spokesman Mac Daniel.
Amtrak was unaffected.
Pan Am trains were unable to pass until the derailed train was moved.
