2024 Tamil Nadu train collision

On 11 October 2024, Bagmati Express, (Train No. 12577), a passenger train with WAP-7 was traveling from Darbhanga in Bihar to Mysore in Karnataka. The train was traveling near Kavaraipettai railway station on the Gudur–Chennai section of the Howrah-Chennai main line in Tiruvallur district, Tamil Nadu at 20:30 IST. The train rammed onto a goods train, which was stationary on an adjacent loop line. The collision resulted in the derailment of 13 coaches of the Bagmati Express, some of which caught fire. Two wagons of the goods train were also damaged. At least 19 people were injured including four people who were seriously injured in the accident. == Aftermath ==

The injured were treated at the Stanley Medical College Hospital in Chennai. The Indian Railways cancelled two trains and diverted multiple trains. The other passengers in the train were transported to Ponneri by buses and later to Chennai Central through Electric Multiple Units of Indian Railways. A special train carried them towards the original destination on 12 October. The tracks were cleared by 14 October and traffic was restored at 9:15 IST. == Causes ==

The train crew indicated that the train switched tracks after automatically after a sudden jolt. A spokesperson of Southern Railway said that there were no casualties due to the safety features of the LHB coaches used on the train. These coaches were designed to withstand higher impact and the coupling mechanism prevented coaches from climbing on top of each other on impact. He also said that the locomotive of the passenger train impacted the brake van of the goods train, which absorbed most of the impact. In July 2025, Commission of Railway Safety reported that it found 'sabotage' as the cause of derailment. == See also ==
