CHICAGO — A section of the city’s transit system was shut down Tuesday after a derailment and fire forced commuters to evacuate a smoke-filled subway line. Terrorism wasn’t suspected, officials said.
Some commuters breathed in smoke and were receiving oxygen, but none of the injuries appeared critical, Chicago Fire Department spokesman Larry Langford told WLS-TV.
The smoke may have been caused by a brake fire or some other small blaze, Langford told the station. He said there was no indication of an explosion.
Service was affected between downtown and the city’s Wicker Park neighborhood on a line that connects downtown to O’Hare International Airport, said Chicago Transit Authority spokeswoman Ibis Antongiorgi.
Emergency crews were assisting commuters and trying to determine the cause of the disruption.
