In one of the worst rail disasters in the country, at least 120 persons were killed and around 100 injured before dawn on Sunday when 14 coaches of the Indore-Patna Express derailed near Kanpur.
The tragedy occurred when the coaches of the Patna-bound train ran off the rails shortly after 3 a.m. near Pukhrayan station, about 60 km from Kanpur city in Uttar Pradesh, railway and police officials said.
Inspector General of Police, Kanpur, Zaki Ahmad told media that 120 people were killed in the accident and over 40 of the injured had been admitted to different hospitals in Kanpur. All others have been given first aid and discharged.
The deaths could rise as some passengers were in critical condition.
He also said that at least 60 of the bodies had been identified with most of the victims hailing from Uttar Pradesh and Madhya Pradesh.
Railway Minister Suresh Prabhu, Minister of State for Railways Manoj Sinha and a host of top railways officials visited the site and supervised rescue and relief operations.
Prabhu ordered an inquiry and vowed to take "strictest possible action" against the guilty.
While the cause of the derailment is yet to be ascertained, Sinha said the accident could have been caused due to rail fracture.
Panic set in when the coaches derailed in darkness, throwing scores of sleeping passengers over one another. Many took a while to realise that a tragedy had hit the train.
Passengers who survived related that there was screaming and shouting as many of the injured were in agony.
The worst hit were the sleeper coaches S1, S2, S3 and S4.
A passenger who survived told journalists that the train stopped a couple of moments after 3 a.m. for unexplained reasons.
"It then suddenly picked up speed," the man said. "And then I got an eerie feeling that the train was rolling down a valley," he said.
"By the time I learnt what had happened, some 20-25 people in my coach had been killed. A six-year-old girl was cut into two pieces," said the terrified man.
Swayambi Mishra, in her early 20s, said she was in S1 coach and did not know what had happened to her father.
A passenger in his 60s added: "God saved me. But most of the people who were with me in the coach seem to have disappeared. I can't find them."
It was the worst train accident in the country after the May 2010 disaster in West Bengal involving Gyaneshwari Express in which some 170 people were killed.
Relief officials described gory scenes, with many passengers crushed by tonnes of steel as several coaches rolled over. Gas cutters were used to rip through the coaches to take out the bodies and the wounded.
Hundreds of bags and suitcases belonging to the passengers were strewn all along the rail track.
National Disaster Response Force (NDRF) spokesperson Krishna Kumar told IANS: "Most bodies are beyond recognition as they are badly crushed."
Ruby Gupta, who was going from Indore to Mhow to attend a wedding, could not find her father after the accident. "Some people are telling me to look for him in the hospital. I need my father back."
Said another dazed survivor: "I was awake when the train derailed. There was a loud noise and then pandemonium broke out. I thought I was dreaming. My wife and children are fortunately safe...."
Survivors said the first to reach the semi-rural site were villagers.
An Uttar Pradesh Police constable rescued five people from the S1 coach. "I felt bad... I had to walk over some bodies, but I had no choice as I had to save those who were alive."
President Pranab Mukherjee and Prime Minister Narendra Modi led the nation in mourning the dead. Modi announced exgratia of Rs 2 lakh for the next of kin of each of those killed and Rs 50,000 for each of the seriously injured.
The governments of Uttar Pradesh, Madhya Pradesh and Bihar also announced financial compensation.
Meanwhile, a row erupted when Sinha visited a hospital in Kanpur and gave an injured woman Rs 5,000 in demonetised notes of Rs 500.
At the accident site, the railways used heavy machinery to separate the tangled coaches. NDRF personnel used hammers to smash the windowpanes to enter the air-conditioned coaches as most doors were locked from inside.
A railway official in Indore said the train, which left there on Saturday and would have reached Patna on Sunday evening, was carrying 1,266 passengers, including 308 in air-conditioned coaches.
The accident led to cancellation and diversion of several trains.
Later, a special train left from the crash site for Patna with the passengers who survived the disaster and could travel.
In the hospitals, the wounded remained frightened by what had happened. Some families got separated as relief officials, unknowingly, rushed a few from a family to one hospital and others to another.
