A tragic accident occurred on July 8, 2025, in Semmankuppam, Cuddalore district, Tamil Nadu, where a school van carrying students was struck by Train No. 56813, the Villupuram–Mayiladuthurai passenger train, while attempting to cross Railway Level Crossing Gate No. 170. The collision resulted in the deaths of three students and injuries to several others, including the bus driver. The railway gate was reportedly unmanned or non-interlocked at the time, and investigations are ongoing to determine the exact cause. Initial reports suggest a mechanical failure that allowed the train to pass without the gate being closed, and there are conflicting accounts about the presence and actions of the gatekeeper. The incident has raised concerns about safety lapses at multiple levels. Tamil Nadu Chief Minister M.K. Stalin expressed condolences and announced ex-gratia compensation of Rs 5 lakh for the families of the deceased and Rs 1 lakh for the injured. The ruling DMK party attributed the accident partly to a language barrier, claiming the railway gatekeeper did not understand Tamil, which may have contributed to the mishap. The accident disrupted train services in the area, and police along with railway authorities are conducting further investigations.
