NORTH BERWICK— The Massachusetts company that owned a trash hauling truck that collided with a moving Downeaster train is asking for more time to answer a civil lawsuit by Amtrak, which is seeking to recover its costs from the crash.

Attorneys for Triumverate Environmental Inc., of Somerville, Mass., filed papers on Thursday in federal court in Massachusetts that gives them until Sept. 26 to answer the complaint from National Railroad Passenger Corporation, Amtrak’s parent company.

On July 11, a Triumverate truck driven by a company employee hit an Amtrak train in North Berwick.

The truck driver, 35-year-old Peter Barnum, of Farmington, N.H., was killed.

Four Amtrak passengers suffered minor injuries.

Foster’s Daily Democrat cites court documents saying Amtrak claims the crash caused more than $3 million in damages.
