On August 2, 1999, two trains collided at Gaisal in West Bengal. The railway minister, Nitish Kumar, resigned. “He resigned in 1999 after 290 people lost their lives in the Gaisal (West Bengal) accident,” Deccan Herald recalled after the train crash in Odisha in 2023. Wikipedia gives at least 285 deaths.
The article added that he “was back as Railway Minister two years later.”
