NEW DELHI: At least six people have died and 24 others injured after a Delhi-bound train derailed early morning today in Bihar's Vaishali district, about 30 km from Patna. Eleven coaches of Seemanchal Express derailed near Sahadai Buzurg at around 4 am.

The superfast train from Jogbani in Bihar to Delhi's Anand Vihar Terminal was running at full speed when the accident took place, officials said. Three of the coaches overturned and the high force of the impact destroyed them completely.

Two teams of the National Disaster Response Force have reached the spot, a railway official said. As per initial probe, the engine separated and chugged forward with the first few coaches and those decoupled eventually derailed. A fracture in the track appears to have caused the accident, the railways said.
