(CNN) — A train derailed Thursday in Ferryville, Wisconsin, south of the Lansing Bridge, according to US Representative Derrick Van Orden. At least a dozen train cars fell off the tracks, according to video recorded by witness Caitlin Nolan.
Other images on social media, along with video Nolan recorded, show some of the train cars in the Mississippi River.
The Black Hawk Bridge connecting Lansing, Iowa, to western Wisconsin has collapsed, according to a spokesman for the Allamakee County Sheriff’s Office in Iowa.
CNN reached out to BNSF which, according to representative Van Orden, is the operator of the train.
Van Orden indicated that his office coordinates with state officials, BNSF and the Federal Emergency Management Agency (FEMA) to “get answers about what happened.”
The congressman’s staff were traveling to the site of the derailment and “will continue to monitor the situation and determine next steps,” their statement said.
Nolan told CNN in an interview that he was on his way to the university around noon when he saw the derailed train.
“I didn’t see fire or smell anything, but I did see several cars in the water on both sides of the tracks,” he told CNN. “There hadn’t been any emergency help until after I passed,” she said.
