NEW DELHI — Dozens of people were killed and more than 100 were injured when a train headed for the capital here derailed in the northern state of Uttar Pradesh on Sunday.

Television news footage from the site of the crash showed rail cars jumbled atop one another and gouged with deep gashes. The train, known as the Kalka Mail, derailed about 75 miles from Lucknow, the capital of Uttar Pradesh.

Rescue workers, aided by the Indian Army, struggled to pull survivors from the wreckage.

“It is so badly mangled,” Harish Chandra Joshi, a senior railway official, told NDTV, a private television news station, describing the effort to rescue several trapped passengers. “Anything you try to lift off, the pressure is put on the bodies.”

Railway officials put the death toll at 60 on Monday as more bodies were being pulled, The Associated Press reported.
