June 1991
The militants stopped the two trains about a kilometre from Ludhiana station by pulling the emergency cords, triggering emergency brakes. They proceeded to open fire inside the trains at around 9:35 p.m. (IST), killing at least 80 passengers. After the attackers fled, the train moved back to Badduwal station, where the rescue team arrived with doctors. Local villagers helped the survivors with food, water, medicine, and mental support. The attacks came less than five hours after polling closed in a national election already marred by violence and interrupted by the assassination of ex-Prime Minister Rajiv Gandhi around a month prior. December 1991
On 27 December, four men, believed to have been Khalistani, boarded a local passenger train travelling from Ludhiana to Ferozepur at Ludhiana. They pulled the emergency cord about 7:30 in the evening near a village called Sohian. Six other armed militants climbed aboard the train at the Sohian crossing. The militants shot at passengers who appeared to be Hindu using AK-47s. All but two of the 49 victims were Hindus. After the massacre, the gunmen left the train and disappeared into the night.
