(NEW YORK) — New York City will pilot a program to install platform barriers at three subway stations, Metropolitan Transportation Authority officials announced Wednesday, a month after a woman died when a stranger pushed her in front of an oncoming train.

The doors, which will create a barrier between the platform and track to prevent people from falling onto the tracks, will be installed at the Times Square station along the 7 line, the Third Avenue station on the L and the Sutphin Boulevard-JFK station stop on the E, MTA Chairman and CEO Janno Lieber said on NY1’s “Mornings On 1” Wednesday.

“It’s going to take a while and we’re going to have to put the money together, which is a little complicated,” Lieber told NY1. “But our goal is to try out these technologies at different places in the system, including three stations, trying out platform doors.”

The pilot program is expected to cost more than $100 million, with the doors likely to be installed at the three locations in 2024, the MTA said. The project is scheduled to be discussed at Thursday’s MTA board meeting.

The announcement comes amid safety concerns in the nation’s largest public transit system. On Jan. 15, Michelle Go, 40, died after she was shoved in front of an oncoming train on the N/Q/R/W line inside the Times Square-42nd Street subway station in what police said was an unprovoked attack.

Following Go’s death, several city officials, including Manhattan Borough President Mark Levine, called on the MTA to install the platform barriers, which are used in transit systems in cities including Paris, London and Hong Kong, as well as along the John F. Kennedy International Airport AirTrain.

Previously, the MTA had said installing platform barriers would be prohibitively expensive and complicated due to the age of the subway system. Last month, the agency released a 3,000-page report from 2020 that found that most of the city’s 472 stations can’t accommodate the protective barriers and that it would cost about $7 billion to install them at the 128 stations that could.

In recent weeks, though, Lieber said the MTA was revisiting the issue. On Wednesday, he said the MTA identified the three stations in the pilot as locations “where the engineering does work.”

Levine called the pilot program a “huge win for safety & efficiency.”

“Truly a milestone in the history of NYC’s subways. Congrats to all who fought for this,” he said on Twitter.

From January 2021 to July 2021, 37 people died after getting struck by a train, according to the MTA.

In 2021, 30 people were pushed onto the tracks, according to the New York Police Department’s public information office. So far this year, as of Jan. 23, five people have been pushed onto the tracks, the NYPD said. A further breakdown of injuries or fatalities was not available.

Among other safety measures, the MTA is looking at piloting new technologies, including thermal sensors and lasers, that would detect when someone has fallen onto the tracks, Lieber said.

The city also recently launched a subway safety plan in response to a spike in crime that involves sending more police, mental health clinicians and social service outreach workers into the subways.

(CHICAGO) — The family of Irene Chavez – a woman who died in Chicago police custody last December after an apparent suicide – filed a federal civil rights lawsuit against the city and several police officers.

“What we know is Irene Chavez died in the care and custody of the Chicago police. The officers knew Irene had mental health challenges,” Andrew Stroth, the family’s attorney, said at a press conference on Tuesday.

Stroth referenced a video of Chavez released last week by the Chicago’s Civilian Office of Police Accountability, where Chavez is seen arguing with arresting officers and telling them that she is a military veteran who suffers from PTSD.

Those details are also documented in a police incident report released by COPA.

“CPD officers ignored this information and failed to modify standard arrest procedures to accommodate Irene’s mental health needs,” the lawsuit, which was obtained by ABC News, alleges.

“Not only did CPD officers refuse to accommodate Irene’s disability during the arrest, but they intentionally escalated the situation by mocking Irene and her friend, and using foul, aggressive language,” the lawsuit says.

The Chicago Police Department told ABC News that it does not comment on pending litigation and has referred all questions about the case to COPA.

The City of Chicago’s Law Department did not immediately respond to ABC News’ request for comment but told the ABC station in Chicago, WLS, on Tuesday that “The City has not yet been served with a complaint and will have no further comment as the matter is now in litigation.”

The documents and videos related to the death of Chavez were released as part of an investigation by the civilian oversight agency looking into Chavez’s death.

Body camera video released by COPA shows Chavez arguing while being arrested hours before her death.

According to police, the 33-year-old woman died after an “attempted suicide” on Dec. 18, 2021, at the 3rd District Police Station. The official cause and manner of death are pending autopsy results, the Cook County Medical Examiner’s Office told ABC News.

Police said Chavez was taken into custody after her involvement in a bar fight at the Jeffery Pub Tavern and was belligerent during processing.

Chavez could be heard by police shouting in the holding cell, the report by COPA said. After about five minutes of silence, an officer went to check on her well-being by looking through the window, the report said. That’s when Chavez was found with her shirt wrapped around her neck, tied to a bench and had a “faint pulse,” according to the report.

Video released by COPA shows officers performing CPR before Chavez was transported to the University of Chicago Hospital. According to COPA, Chavez was in “critical condition” at the time and was pronounced dead at the hospital.

Iris Chavez, Irene’s sister, accused police of neglect and said officers should have recognized that her sister was struggling with mental health.

“[I’m] Looking at the video and saying to myself, why aren’t they doing this instead? Why didn’t they do this? Or why is he talking to her like that?” Iris Chavez said.

According to the lawsuit, Irene Chavez was a “queer Afro-Latina” woman from Chicago and was a “decorated military veteran” who served in combat zones.

“After her honorable discharge from the military, Irene developed serious post-traumatic stress disorder (“PTSD”) and struggled with alcohol dependency,” the lawsuit says.

According to the lawsuit, Chavez was “in the midst of a mental health crisis” when she was arrested and had relapsed to drinking that day after being sober for a month.

“Both Irene and her friend repeatedly told CPD officers that Irene was a veteran, that she had PTSD, and that she needed hospitalization,” the lawsuit says.

Irene Chavez is one of two women to die in Chicago police custody within less than two months.

COPA is also investigating the death of London Marquez, 31, who died on Jan. 27. According to Marquez’s family, she was pregnant at the time of her death.

Chicago police declined to comment on that case and referred questions regarding both cases to COPA.
