Nice! Are those guys train operators?

No. These are wagon workers. When the train is attached to the locomotive, they check the brakes and the rest of the similar work.

The back of a truck loaded coal wagons for heating. Overhead wire for heating after the station Lisakovsk will not.

@tzhs Thanks for explaining! Very interesting operation.
