CHICAGO (STMW) — Red Line trains are rerouted Wednesday night after a train hit and critically injured a person at the Chicago Avenue subway station on the Near North Side Wednesday evening, officials said.

The southbound Red Line train struck the person near the station, in the 800 block of North State Street, some time after 9 p.m., CTA spokesman Brian Steele said, citing preliminary information.

Chicago Fire Department crews found the person pinned under the train, a Fire Media Affairs spokesman said. Paramedics took the person to Northwestern Memorial Hospital in critical condition.

The transit agency is rerouting Red Line trains to the elevated tracks between the Fullerton and Cermak/Chinatown stations because of the incident, Steele said.

A bus shuttle is also in place to take passengers between those stations.

Information on the circumstances surrounding the incident was not yet known.
