We have similar buses in Leningrad only with miners. They go to mines and houses. They can be distinguished after the change by the characteristically painted eyes. So coal dust is filled, and it seems to be deceived. In one of the buses, a mother and her daughter were injured. Looking around the men in the bus, she sees that everyone's eyes are painted, she goes out of the bus with the words - let's go daughter, another bus we'll look for, here some kids are going.
