Fourteen Pan Am Railways freight cars derailed in Westford Thursday, company officials said.
At about 7 a.m., the cars went off the tracks on Bridge Street at North Main Street, said Cynthia Scarano, executive vice president of Pan Am Railways Inc.
“We were pretty lucky,” she said. “They all landed upright. No merchandise spilled.”
The cars were part of a 63-car freight train carrying various supplies, including lumber and paper. Six of the derailed cars were loaded, while eight were empty, Scarano said.
Police and Pan Am employees were at the scene Thursday, said Westford police Sergeant Marc Proia. No injuries were reported.
Bridge Street was to remain closed at North Main Street and Pine Ridge Road until the cars were cleaned up, he said.
Scarano said the company would investigate the cause of the derailment, which could take a few days. She said she was not sure if it were weather-related.
The derailment came a day after four train cars carrying automobiles derailed in Gardner.Jacqueline Tempera can be reached at jacqueline.tempera
