One person was killed and nearly two dozen others were injured in South Jersey on Monday morning when a New Jersey Transit light rail train struck a tree on the tracks, the commuter rail said.

Just after 6 a.m., a River Line train traveling south from Trenton collided with a chunk of tree near the Roebling station in Mansfield Township, killing the train’s operator, New Jersey Transit said in statement.

Photos of the accident show the window of the front car smashed in and the tree partly under the train.

There were 42 passengers onboard, the statement said, and 23 people were treated for non-life threatening injuries, most of which were minor.

New Jersey Transit police officers were on the scene, and the agency was investigating the crash and how a chunk of a tree ended up on the tracks while a train was en route, the agency said.

Gov. Phil Murphy said on social media that he had been briefed on the accident and that an investigation was underway.

Some services were suspended.
