Another caving-in happened not long ago not far from Berezniki station in the Perm region. It's about 5 meters in diameter but it was enough for the railway car to fall into it.
It happened in about 400 meters from the "big" gap, that formed in the summer of 2007 and reached about 50 meters in diameter.
The gap collapsed under the last car of the standing train.
In the early morning somebody shot the picture of the car hanging just above the pit. The pit seems to be small and insignificant but it may expand. And nobody knows where the next caving-in will happen...
