Thanks for posting.... Working the brakeman's spare board I've worked at a few wrecks site with CN's 250 ton hook.. Maybe 3 tops.
As for the Russian video.. No shortage of man power. It must have been stationed close by . Although a crew might be able to re-rail the car around a yard with a supply of blocks it would be difficult to do out on the road, best left to the experts. Besides the re-railers that hang on the engine are really heavy. It takes two crew members to handle them.
Now days a road repair truck (car dept) handle this type of thing if thy can drive to it.
I'm not sure the big hook would have worked out underneath the over head wires?
