A freight train derailed in North Bergen just before 4 p.m. along Tonnelle Avenue near Route 3, prompting a large emergency response.
• Officials said one of the train cars spilled a chemical identified as ethyl acetate, with Hazmat teams working to dilute and contain it.
• No injuries have been reported, and authorities say there is no confirmed danger to the public, though Route 3 is closed in both directions near the incident.
