Video starts with a passing freight train. One of the tankers appears to be in a bit of distress (it has been highlighted in the video)
An entire wreck train is dispatched, and apparently all that was done was to assemble some blocking under the errant truck and pull it back onto the railheads with another diesel. Unfortunately there may be a bit of additional info in the subtitles, but Google can't translate those (not that it does a particularly good job with Russian anyway). The comments, on the other hand reveal plenty of accusations of featherbedding
We do get a good look at a Russian "big hook" though...
(I ran across the above while reading a thread on 4chan's transportation board, in a thread dedicated to a Q&A session about Russian railroads. I'd asked about why so many of their freight railcars were so uniformly short, and the answer was 22-ton axle load limit--which explained why the only longer tankers in the train had eight axles.)
