Gwinnett County fire is assisting Norcross police with a train vs. truck incident at the intersection of Holcomb Bridge Road and South Peachtree Street, police said.
No injuries have been reported, Gwinnett fire Deputy Chief Charles Wells said.
The train bisected a tractor-trailer shortly before 5 p.m., according to Channel 2 Action News.
Roads were closed in the area as crews worked to cleanup the debris from the truck.
Just after 8 p.m., Norcross police said all railroad crossings had been reopened, except the crossing at Holcomb Bridge Road.
Police are still investigating the cause of the crash, but signs in the area say trucks are prohibited and show an image of a truck getting stuck on the tracks.
