What I see as evidence for the railway roller bearing hypothesis is the derailment happened at the 6th car behind the diesel locomotives and not _AT_ the locomotives.
If it was a flooded track issue the locomotive, as the heaviest piece of the train would have derailed first.
Yet the _Sixth_ rail car was the one that derailed.

The areas with least maintained railway tracks will put the most wear and tear on roller bearings.
It is also where the Russian railcar & locomotive fleets have been the most neglected.
So you all need to be watching for more of this in the Russian Arctic & Far East, as I have.

The Russian pattern of the most neglected track meeting the most neglected engines & rolling stock will cause more & more derailments starting in the arctic, then the Far East.
Then derailments in the Caucuses, moving towards Moscow/St Petersburg.
Finally derailments of the repair trains.
8/
The movement of DPRK artillery shells, weapons and now troops through overused and ill maintained Trans-Siberian rail stock & tracks in the arctic summer will show how non-existent Russian preventive maintenance has been since the April of 2021.😈

You find both mission failures & gross errors were "excluded data" 2/
And that both increased altitude and the number of combat boxes involved made CEP worse.

I've spent the last few hours reposting my 2022 to date take down's of Alex Vershinin's "Truck beer math" (from the Nov. 2021 War on the Rocks article "Feeding the Bear") which I used to review this Tochnyi article⬇️
TLDR: Tochnyi screwed up & used Vershinin's disproven work. 1/
Specifically this bit stating Russian trucks did three trips a day because they spent one hour loading and one hour unloading trucks.
That is, like Alex Vershinin, they assumed mechanized logistics loading times with pallets & forklifts⬇️
2/
This is Alex Vershinin's truck "Beer Math" for comparison.
It assumes 45 miles vice 50 km, but both show the same mirror imaging of Western mechanized logistics on Red/Russian Army non-mechanized logistics.
