Six persons were killed on Wednesday when nine coaches and the engine of an Express train heading to Delhi from Malda in West Bengal derailed in Rae Bareli in Uttar Pradesh, officials said.
More than 60 people were also injured when the New Farakka Express derailed near Harchandpur around 6.05 a.m. Nine passengers have been critically injured, a police officer said.
Most passengers were asleep when the disaster occurred. One passenger who did not give his name told journalists at the site that he woke up after hearing a loud thud and realized that many coaches had gone off the tracks.
The injured were taken to the Rae Bareli district hospital. Later, they were shifted to Lucknow and then sent to Delhi in buses and a special train.

He said the seriously injured would get Rs 1 lakh and Rs 50,000 would be given to those who suffered simple injuries.
