India is set to initiate an investigation on Tuesday regarding a train collision in West Bengal that resulted in nine fatalities and over 50 injuries. This follows a statement from a senior railway official attributing the accident to driver error. The death toll was adjusted from 15 to nine after the incident on Monday, where a freight train collided with a passenger train en route from Tripura to Kolkata. Chetan Kumar Shrivastava, the general manager of Northeast Frontier railway, informed Reuters that the investigation by the top railway safety official would commence on Tuesday. He mentioned that the inquiry would include eyewitness accounts, examination of official documents, and statements from railway officials concerning signaling and other safety protocols. On Monday, the chief railway official stated that the driver of the freight train, who perished in the accident, ignored a signal, leading to the collision with the Kanchanjunga Express, which was stationary near a station in the Darjeeling district. A railway spokesperson confirmed there were 1,400 passengers aboard. However, media reports indicated that the automatic signaling system was malfunctioning since Monday morning, prompting authorities to advise slower train movement using 'paper signals'. Opposition leaders in India criticized the railway safety record under Prime Minister Narendra Modi's government, citing negligence. This incident occurred just over a year after a major rail accident in Odisha killed approximately 288 people due to a signaling error. Indian Railways, a state-owned entity known for its congestion, operates the world's fourth largest train network, transporting 13 million passengers daily and nearly 1.5 billion tonnes of freight in 2022. Jaya Varma Sinha, the chairman of India's railway board, addressed the media on Monday, urging a reduction in human error and announcing the implementation of a nationwide anti-collision system. Partial train services resumed on the affected tracks on Tuesday, with some trains being rerouted and others operating at reduced speeds, according to railway officials.
