BUCKSPORT — The cause of a derailment near the Verso Paper mill Tuesday remains under investigation.
Cynthia Scarano, executive vice president for Pan Am Railways, said four empty boxcars that were part of a 34-car train went off the rails shortly before 11 a.m. March 12.
The derailment occurred in a switching yard along the Bucksport waterfront, behind Bucksport House of Pizza.
The cars involved derailed where an access road to the Webber Dock crosses the rail line. A Bucksport police dispatcher said public safety officials were not notified of the derailment, however, because that is not a public road.
None of the four cars appeared to have tipped over as a result of the derailment. The following day, however, one was being propped up by a pile of rail ties and other pieces of wood underneath it because some of its wheels had sunk into the mud.
Heavy machinery was brought to the scene, and crews worked to get the cars back on the rails. By Thursday afternoon, the scene of the derailment had been cleared.
