CHICAGO — Service has resumed but delays remain after a partial train derailment on CTA’s Green Line Thursday.

[Significant Delays] Some Green Line trains are running with residual delays following an earlier derailment near 47th. Service is resuming. — cta (@cta) June 6, 2019

The derailment happened at about 11 a.m. at 47th Street, halting service between Ashland/63rd-Cottage Grove and Roosevelt.

CTA officials said one of the train’s four cars came off the track and was leaning, but did not fall. CTA officials are investigating what caused it to happen.

Passenger Drake Hills had just gotten on the Green line, headed from the South Loop to Hyde Park, when he noticed the train started to wobble

“We looked up and saw there was a lot of smoke coming up from in front of us,” he said. “We saw the car in front of us had tilted to the left significantly.”

Passengers said there was a sudden jolt and the train came to an abrupt stop between Calumet Avenue and Prairie Street.

80 Chicago fire personnel responded and went into triage to determine which passengers should be evacuated from the cars first.

“They got people who had some back and neck pain off first,” passenger Jane Miller said. “It was mostly trying to figure out the best way to get them down since it’s so elevated.”

Of the 30 people on board the train, seven people were transported to area hospitals with minor injuries. All other passengers refused treatment.

According to CTA’s website, trains are operating in two sections:

between Ashland/63rd-Cottage Grove and 51st , and,

, and, between 35th-Bronzville-IIT and Harlem, only.

While Green Line service is suspended, CTA will provide shuttle service between Ashland and Roosevelt. CTA officials also suggest alternate travel options such as Red Line train service or bus routes 3, 4 and 29.
