SACO — A freight train derailment snagged traffic for several hours Friday afternoon.

Around 11:30 a.m. Friday, the Saco Police Department put out a notice that a train had slipped off the tracks and was blocking Industrial Park Road. Police asked those who typically use the nearby highway exit to instead enter or leave the highway on Main Street.

The train, owned by Pan Am Railways, consisted of a locomotive and a freight car. It had been headed East, on what is locally known as the Industrial Park Spur, when the locomotive derailed slightly. The locomotive remained upright, while the attached car, which was carrying lumber, was still on the tracks, according to Cynthia Scarano, Pan Am’s executive vice president.

Scarano said Friday afternoon that officials had not determined the cause of the derailment and were investigating the incident.

No one was injured in the derailment, according to Deputy Police Chief Jeffrey Holland.

Pan Am workers were on the scene mid-day, digging out snow and pouring down rock salt as temperatures hovered in the single digits. Holland said a crane was going to be brought to the scene to lift the locomotive up onto the rails. Officials hoped to have the train back on track by late afternoon, he said, to avoid back-ups during peak commuting times. Police had planned to have a number of officers on duty, and had notified press and turnpike authorities, but by 4:30 p.m., traffic appeared to be flowing again in the area.
