Train service was halted on the CTA Red, Brown and Purple lines Tuesday morning after a man was found dead on the tracks at the Fullerton station.
Emergency crews were called to the station about 6:30 a.m. to recover the body of a man, thought to be in his 40s, on the tracks, according to Chicago Fire Department Chief Juan Hernandez and Chicago Police.
It was not clear whether the man was struck by a train, but detectives believe the death was a suicide, police said.
Chicago Fire Department spokesman Larry Langford said a severed head and a leg on the tracks were reportedly found on the tracks.
The train stoppage led to packed bus stops, angry tweets and a lot of frustrated commuters.
As of 8:15 a.m., Brown Line service was suspended between the Belmont and Merchandise Mart stations, according to the CTA. Red Line service was temporarily suspended between the Belmont and North/Clybourn stations. Purple Line trains were only operating from Linden to Howard.
By 9:30 a.m., service was resuming, but delays were still expected.
Shuttle buses were made available to CTA customers, to provide connecting service through the affected areas.
