One man was seriously injured Friday morning following an accident involving a westbound Norfolk Southern train and a passenger vehicle at the Liberty Street railroad crossing.

Suffolk Police and Suffolk and Fire and Rescue responded just after 5 a.m. to the accident. The man, who was the only person in the vehicle, was treated at the scene, according to a news release, before he was taken by ambulance to a local hospital for further treatment.

The train did not derail, and all crossings are clear.

The investigation remains ongoing at this time.
