    The accident occurred at about 7:00 a.m. Moscow time (0300 GMT)on Sunday, when the passenger train was traveling from the Chechenrepublic capital Grozny to Moscow. Five cars jumped the tracks after the train's third car detached from its second car, the Interfax quoted officials in the Emergencies Ministry's branch forthe Moscow region as saying.

    As many as 350 passengers, who were in the Grozny-Moscow train,have boarded another Moscow-bound train, which is expected to arrive at the Paveletsky train station, Beltosv told Interfax.

    The government of Chechnya is to send a commission to Moscow tohelp investigate the cause of the derailment, said Chechen Prime Minister Sergei Abramov.
