The National Transportation Safety Board will not be investigating a June 30 freight train derailment in Bensalem that put two Bucks County towns on alert, resulted in evacuations, closed a major road and suspended commuter train service for hours.
Overnight Tuesday, crews worked to successfully remove the 16 derailed cars that had jumped the tracks and toppled into a roadbed, CSX spokesman Jonathan Stuckey said Wednesday.
The work crews were still working on the track and site restoration as of late Wednesday afternoon with the hope of reopening the line sometime later that day, Stuckey said.
Crews work at the train derailment near Neshaminy Falls station in Feasterville-Trevose on June 30, 2026.
An NTSB spokesperson confirmed that the agency will not be investigating the accident, but a Federal Railroad Administration spokesman said Wednesday that it is monitoring the response, recovery and service restoration activities.
A safety report detailing the cause of the derailment must be submitted to the FRA within three months and it will be available online, the spokesman said.
CSX investigators are working to determine what caused the 72-car freight traveling eastbound to derail between Street Road and the Neshaminy Falls train station shortly after 2 p.m. Only CSX trains operate on the portion of the rails where the accident occurred, Stuckey said.
The incident remained under investigation Wednesday, Stuckey said.
Kim Vu lives on Grove Avenue and her backyard backs up to the tracks where the derailment happened.
On Tuesday afternoon she heard a noise and then minutes later there was knocking at the front door, she said Wednesday. She found two police officers and at least three patrol cars on the street. They told her something happened and she needed to evacuate.
“I asked them how long I get it,” she said.
Kim Vu, who lives next to the Neshaminy Falls Station, talks about having to evacuate due to the June 30 train derailment and finally getting to return home in Feasterville-Trevose on July 1, 2026.
She only had five minutes to gather her belongings and leave, Vu said.
“That’s what the scariest part cause I never left my home and don’t know when I can come back,” Vu said.
She was able to return home around 8:30 p.m., she said.
No one was injured when 16 freight cars located toward the rear of the train derailed, but safety concerns arose after three cars were found to display hazardous material placards, officials said.
Two cars were confirmed to be carrying adipic acid, a solid chemical used in the production of polymers and synthetic materials and isopropanol alcohol, a flammable liquid used as a disinfectant and solvent.
Bensalem police officers went door-to-door on Grove Avenue and Old Lincoln Highway to notify residents and businesses in Lower Southampton and Bensalem to evacuate before they knew no substances had leaked.

Bucks County put out an emergency alert advising nearby residents in a one-mile radius of the derailment to shelter-in-place and others to avoid the area.
Emergency and Hazmat crews from Bensalem, Bucks and CSX eventually confirmed no hazardous materials had leaked or spilled in the accident. The evacuation and shelter-in-place orders were rescinded around 4:30 p.m.
The busy corridor is shared by SEPTA, Amtrak and freight trains outside of Philadelphia.
No damage was reported along the West Trenton rail lines, which run parallel to the CSX line, but SEPTA suspended commuter service for five hours while the investigation was underway.
The Neshaminy Falls commuter station off Bristol Road remained closed Wednesday and it would not reopen until after track restoration work was completed, according to a SEPTA spokesman.
Part of heavily traveled Bristol Road near the scene was also closed for seven hours before fully reopening Tuesday night.
Crews continue to work at the June 30 derailment site near Neshaminy Falls Station in Bensalem on June 30, 2026.
