A train crash occurs when a train collides with another train, vehicle, or object, often resulting in significant damage and potential injuries. These incidents can happen due to various factors, including human error, mechanical failure, or obstacles on the tracks. Emergency responders typically arrive quickly to assist those affected and investigate the cause of the crash. Safety measures, such as improved signaling systems and regular maintenance, are essential to prevent such accidents. Organizations like the National Transportation Safety Board (NTSB) often conduct investigations to determine the causes and recommend safety improvements.
