News reports from Russia quote witnesses as saying they heard an explosion before the train abruptly stopped, causing four carriages to derail. Two carriages were overturned.
The injured were taken to two area hospitals.
Russian President Dmitri Medvedev Saturday hosted a conference on the train crash and observed a minute of silence for the victims.
