WILTON - A Greenfield man was flown by helicopter to a Massachusetts hospital on Wednesday after a train crashed into the truck he was driving, causing him serious injuries.

Police say Lawrence Fox, 48, of Greenfield, suffered serious internal injuries when his 2000 International dump truck collided with a single locomotive belonging to Milford-Bennington Railroad.

The crash occurred around 7:40 a.m. on Wednesday as Fox's truck was traveling south on Burns Hill Road and approaching the railroad crossing, said police.

The locomotive was traveling north on the tracks entering the Burns Hill Road intersection near the police station when the collision took place, according to authorities.

"Based on the preliminary investigation and witness statements, the railroad crossing signals were activated at the time, and the dump truck went through them," Chief Brent Hautanen said in a statement. "As the truck crossed the tracks, it was struck by the train."

After the collision, the truck was thrown off the tracks and hit a utility pole, damaging the structure, said police.

The single locomotive was driven by David Raymond, 49, of Allenstown. He was not injured in the accident, according to police.

Fox was transported by helicopter to UMass Memorial Medical Center in Worcester, Mass.

The accident is still under investigation by Hautanen, who was not immediately available for comment. Assisting at the scene was the Wilton Fire Department, Wilton Ambulance and members of the New Hampshire State Police Commercial Vehicle Unit.
