Sunday, killing at least 31 and injuring 100 others, officials said.
The Kalka Mail train was on its way to Kalka, in the foothills of the Himalayas, from Howrah, a station near Kolkata in eastern India, when 12 coaches and the engine jumped the tracks at Malwan station, near the town of Fatehpur in Uttar Pradesh state, senior railway official A.K. Jain said.
The cause of the derailment was not immediately clear but it appeared that the driver applied the emergency brakes, Jain said.
At least 31 people were killed and rescue workers pulled at least 100 injured passengers out of the wreckage, said Brij Lal, a state police official.
The accident site was a pile of twisted metal. At least one coach flew above the roof of another ahead of it and was dangling precariously, television footage showed. Another coach was thrown away from the rest of the train.
The toll was likely to rise as rescuers made their way through the coaches and used gas cutters to cut through the mangled metal, Lal said. Rescue efforts continued late into the night.
"We're trying to cut into the coaches and rescue those still trapped inside," Lal said.
A senior railway official, H.C. Joshi, told CNN-IBN news channel that rescuers were struggling to free at least five people pinned under the wreckage of one of the worst-damaged coaches.
Medical personnel rushed to the area, about 75 miles (120 kilometers) southeast of Lucknow, the capital of Uttar Pradesh state.
