"Federal Probe into NYC Subway System Escalates Following Derailment and Human Error Claims"
The National Transportation Safety Board (NTSB) is launching an investigation into the entire New York City subway system following a collision and minor derailment on the Upper West Side that injured over 20 people. This incident marks the second serious subway accident in Manhattan in just over a month. The NTSB will review the MTA's operations and safety protocols, while the MTA highlights the rarity of such events given the volume of train trips scheduled annually. The collision occurred when an out-of-service train struck a passenger train at a rail switch, with the cause still under investigation. Service disruptions continued into the following day as crews worked to repair the damage.
