ATLANTA — Atlanta city leaders are voicing frustration after nine people were injured in an escalator malfunction at a MARTA station following a recent Beyonce concert.

Around midnight on Tuesday, the escalator inside the MARTA Vine City location reportedly sped up briefly before coming to a sudden stop. The panic led to one person suffering a broken ankle and seven people being hospitalized, officials say. One person declined medical transport.

According to a statement from MARTA, the injuries occurred during a chaotic moment on an escalator, when a person began screaming and running because of a bug and that commotion sparked a panic.

City Council Transportation Committee Vice-Chair Marci Collier Overstreet says she is saddened that the incident led to people being injured.

She wants to see MARTA’s escalator’s maintenance records and a system-wide risk analysis.

“This incident was a near‑catastrophe. Dozens could have been seriously hurt or worse,” said Overstreet. “We don’t know the names of those hurt, but I hope that at the least MARTA is checking in on these people. One thing I do know: our city must understand exactly what went wrong to ensure this never happens again.”

She adds the public needs to be assured that MARTA is safe for all of the events the city plans to host.

Overstreet supports MARTA’s investigation, however, she insists it must be fully transparent, public, and accountable.

“It is absolutely necessary that council members, especially those that serve on the transportation committee are briefed,” she said. “We’re going to need some clarity and accountability.”

According to city officials, MARTA has faced recurring escalator and elevator issues over decades and “a $40 million modernization program launched in 2015 remains incomplete.”

Overstreet says with more major events coming to Atlanta, Overstreet says MARTA officials “must work to ensure we develop stronger transit safety protocols.”
