Speaking to reporters here, Railway Minister Mamata Banerjee said that the train comprised 10 coaches of which five derailed and three toppled over as also the engine.
She said two bodies were found in a overturned bogie, while 47 passengers were injured. Six passengers were trapped in another capsized bogie.
"Maoists blew up a portion of a railway track which caused the derailment. There were also three to four blasts nearby to deter rescuers," Banerjee said.
The blast occurred between Manohar and Posoita railway stations just in front of the engine of the train, some 20 minutes after a pilot engine had passed.
Superintendent of police (rail) A B Homker said in Ranchi, "Railway staff and rescue teams have reached the spot, and are cutting open the bogies to rescue the injured passengers."
