A spokesman for the New York Fire Department said 37 people are suffering non-life threatening injuries in relation to the A train derailment Tuesday morning.
Passengers were evacuated after two cars derailed in Harlem at 10:00 AM, according to the chairman of the MTA, Joe Lhota.
Lhota spoke from the scene at 125th Street at noon on Tuesday. He said that the train's emergency breaks engaged for unknown reasons, causing the two of the eight cars to come off the tracks.
"The train bucked forward, it bucked backwards, and in the process of doing that, two of the - there are eight cars on this train - two of the cars derailed, they scraped the side of the wall," Lhota recounted.
Lhota says everybody on the derailed train, as well as three other trains nearby, have been evacuated by fire department personnel.
Six people went to area hospitals to seek treatment for smoke inhalation.
The New York City Riders Alliance issued a statement praising the MTA personnel and emergency responders at the scene, but also pointing to Governor Andrew Cuomo to shoulder the blame.
"Scared subway riders have one question: where is Governor Cuomo? As the subway crumbles from decades of neglect, Governor Cuomo continues to point fingers instead of coming up with a credible plan to fix the MTA," said Executive Director John Raskin.
Firefighters said they responded to a report of a smoke condition on the train at 9:45 a.m. at West 125th Street and Saint Nicholas Avenue. Emergency responders are on the scene, and the incident is under investigation.
