An accident relief train with paramedic staff was sent to the site, according to a North East Frontier Railway spokesperson.[9]
After the derailment, the villagers came forward to help the trapped passengers.[10] Emergency services arrived at the scene within a few minutes and the trapped passengers were rescued and were rushed to Jalpaiguri district hospital and Maynaguri rural hospital. Passengers in critical condition were sent to North Bengal Medical College and Hospital in Siliguri.[11]
According to Railway minister, Ashwini Vaishnaw, initial probe of the incident pointed towards a technical glitch in the locomotive of the train.[12]
A part of the New Jalpaiguri–New Bongaigaon section line was closed due to extensive damage to the tracks. The line was opened for operations on 15 January following necessary repairs.[13]
Five days later, a team of inspectors from the State Forensic Science Laboratory (SFSL) of West Bengal were deployed at the scene. The inspectors reviewed the scene by examining the engine's traction motors and the derailed coaches. The team along with Soma Das Mitra, the deputy inspector general (railways) of the state police also interviewed the train driver.[13]
The report points out that the last scheduled maintenance date of the locomotive on 9 January 2022 was skipped and the locomotive hadn't been inspected since its last inspection on 11 November 2021. It also stated that one of the traction motors fell off the locomotive, prompting the drivers to apply emergency brakes to the speeding train causing the last two assemblies of the locomotive to derail.[15]
Final safety report
The final safety report issued by the Commission of Railway Safety (CRS) revealed that the locomotive bearing number 22375 had skipped numerous inspections. According to the report, the WAP-4 locomotive must be inspected after every 4,500 km but the ill-fated locomotive was running continuously for 16,000 km without any maintenance.[16]
The report added that the locomotive was a 'missing link loco'. All locomotives have their mother divisions where they undergo maintenance and repairs. This locomotive was running in the National Capital Region (NCR) far away from its division. This led to irregular maintenance. It also stated that these 'missing link loco' undergo maintenance at locations without proper infrastructure and these 'ghost inspections' were a matter of concern for the Indian Railways.[17]
Response
India's Railway minister Ashwini Vaishnaw announced an ex-gratia payment of ₹5lakh each to the next of kin of those who lost their lives and ₹1 lakh each for seriously injured passengers.[18] He further announced ₹25,000 for passengers with minor injuries. Chief Minister of West Bengal, Mamata Banerjee and Prime Minister Narendra Modi also assisted the injured people by providing cash amounts to them.[citation needed]
