MOSCOW - A defect of a railcar's bogie and a human factor are currently examined as possible reasons behind an incident in which four railcars of a passenger train en route from Yekaterinburg to Adler ran off the rails in Mordovia on Saturday, a source with the local technical supervision service told Interfax.

‘A possible defect of bogies or that of the rail track, including its possible overheating and deformation, and also a human factor are currently being viewed as the most likely causes of the incident,’ the source said.

The locomotive remained on the tracks, but the leading four cars were partially derailed, he said.

‘Two cars turned over on their side, and the other two remained on their bogies,’ the source said.Conflicting reports have been coming as to the number of possible casualties.
