The death toll rose to 80 as workers sifted through the wreckage in Northern India on Monday.  At least 350 more were injured in the accident, one of the worst rail disasters to hit the country in years.

The accident occurred on Sunday in Uttar Pradesh state after the New Delhi-bound Kalka Mail suddenly stopped, derailing over a dozen carriages that piled on top of one another.

It was one of the most serious cases of rail accidents in India, said Sandeep Mathur, chief public relation officer of North Central Railways, who added an inquiry would be launched.

Rescue teams have struggled over the past twenty-four hours to locate and remove bodies from the rubble.
