Over 20 injured in shocking New York subway collision

The collision transpired around 9:00 AM Eastern Time on Thursday in the Upper West Side near the 96th Street station. The incident involved a passenger train with about 300 commuters and a service train with just four technical support workers onboard.

Officials are investigating to identify the causes of the accident, which led to traffic disruption in Manhattan.

In an interview with AP, Richard Davey of the New York City Transportation Board stated that the service train, which was not in service, experienced delays as the emergency brakes had been repeatedly activated. "Two trains are not supposed to collide. We will deeply investigate this incident," he said.

Photos shared by city authorities on social media depict the passenger train partially derailed in an area with switches. Officials mentioned that there were no immediate signs of equipment malfunction and are probing if human error was a factor in the accident.

Evelyn Aguilar, a 19-year-old heading home to Brooklyn, described the incident as "terrifying" in an interview with the New York Daily News. "Personal belongings were flying throughout the train. My head hit the door's window," she added.
