CHICAGO (CBS) — Brake smoke on a train at the Roosevelt Red Line station prompted the CTA to reroute the line overnight.

By 2:45 a.m., Red Line trains were running normally again, but for about an hour and a half before that, the trains were rerouted to the Brown-Purple Line, Loop and Green Line tracks between the Roosevelt and Cermak-Chinatown stations, according to Chicago Transit Authority spokeswoman Lambrini Lukidis.

Commuters were evacuated from the Roosevelt subway station, but there were no injuries, Lukidis said.

Fire Department crews initially called a still-and-box alarm and called five ambulances to the scene, and crews were seen entering the subway stop in full gear.

But firefighters found only light smoke from the train’s brakes, according to Fire Media Affairs.
