An Amtrak train derailed in central Vermont on Monday morning, Vermont State Police told ABC News.
The Montpelier Fire Department said that at least four people were reported injured when several cars went over an embankment, reported CNBC.
A total of five occupied vehicles were involved, with three falling into the steep embankment, the fire department told ABC.
The cause of the incident, which occurred around 10:30 a.m. EST, was not immediately identified, CNBC reported.
Train 55 was part of the railway company’s “Vermonter” service, which runs between Washington, D.C. and St. Albans, Vermont, Amtrak wrote on their blog.
Amtrak added that there were no “immediate reports” of any life-threatening injuries.
Police and emergency crews are responding to the scene, and investigators from the Federal Railroad Administration were also headed to the derailment site, reported ABC.
“We are aware of the derailment of train 55 in VT. Emergency personnel are on the scene & we are assessing the situation,” Amtrak tweeted. “Updates to follow.”
Earlier this year, another Amtrak train derailed in Philadelphia, killing eight and leaving at least 200 more injured.
At the time, officials said the train was traveling at more than 100 mph, over twice the speed limit, when it jumped the tracks en rote to New York.
