A passenger train derailed on Thursday in northern India, resulting in the deaths of at least two passengers and injuring 20 others, according to a railroad official. The cause of the accident is currently under investigation.

Naveen Kumar, a state relief commissioner, reported that rescuers and ambulances swiftly arrived at the accident site to assist the victims. The train, en route from the northern city of Chandigarh to Dibrugarh in northeastern Assam state, derailed near the town of Gonda, causing several coaches to overturn.

Television images from the scene showed scores of passengers standing beside the derailed coaches, anxiously awaiting assistance from rescuers. This incident adds to a series of recent train accidents in India, highlighting ongoing concerns about rail safety in the country.

In June, a tragic collision occurred in the eastern state of West Bengal when a cargo train rammed into a passenger train, killing nine people and injuring dozens more. Investigators attributed that accident to the cargo train driver’s failure to heed a signal, which led to the fatal crash.

India’s railway network, one of the largest in the world, serves over 12 million passengers daily on 14,000 trains that traverse 64,000 kilometers (40,000 miles) of track. Despite government efforts to enhance rail safety, the country continues to experience several hundred rail accidents annually, most of which are attributed to human error or outdated signaling equipment.
