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.

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.😈
The semiconductor industrial base is the foundation of 21st century economic & military power.
The USSR only ever produced single detector element technology like Long Wavelength Infrared (LWIR) Infrared Line Scan (IRLS) or scanning infrared Search and Track (IRST) like those on the MiG-29 Fulcrum A.

The USSR never produced any of the classic nodding or spinning mirror LWIR Forward Looking Infrared (FLIRs) sensors that the US introduced during the Vietnam war.
In fact there is no evidence Russia was able to sustain any of the large Soviet semiconductor industry.

The vast majority of US military aid to Ukraine was in fact spent inside the USA to replace vastly overpriced by the Biden Adm. National Guard & Air Guard surplus weapons.
Spending aid money buying Joint Light Tactical Vehicle (JLTV) to replace NG surplus Humvees
...was just one of the aid grifts @JakeSullivan46 NSC crew played to pretend they were helping Ukraine while not offending Russia & buying US Defense contractor kit.
Pres. Trump is literally parroting Russian reflexive control scripts from Biden Adm.
This should not be a surprise as I've pounded on the fact for 2 years that Russia has mapped & fed to each specific US tribal & professional demographic the data to eat up messages/memes Russia wants those groups to believe.
This @sambendett thread here makes Russia seem like a poor kid looking through a candy store window at the "candy" of Ukrainian ground resupply drones.
I mean, seriously, Russia is now introducing a camel transport corps because the Russian startups and big defense contractors cannot produce supply UGV's at scale to deliver potable water to front line troops.
This 🧵by @GrandpaRoy2 demonstrating the increasing battlefield obsolescence of tube artillery in the face of fiber optic fiber guided FPV drones is a useful jumping off point the following:
66% of RuAF AFV's & equipment killed in Jan 2025 were victims of drones
Back in November 2024 I did a long thread on how drones were an "effectiveness revolution" on the battlefield and we would see drones displacing other battlefield weapons because of it.
It appears the collapse of Russian Army motor transport is nearly complete and hippo train (mules & horses) are being pulled out of the 19th century for the "2nd strongest Army in the world."
Being a WW2 historian of electronic warfare and logistics has it's advantages when it comes to looking up US Army standard operating procedures for horse & mule logistics.
See #1 thru #9 below and consider if a Mobik from a Russian city could do them.

Russian Mobiks have a hard enough time maintaining trucks, cars and tractors. How do you think they will care for a mule?
Again, from the US Army Wagoner S.O.P.:
"ROUTINE DUTIES OF THE WAGONER
It is a good plan to have a fixed time for every routine duty, as then there will be no chance of over looking anything. Certain duties should be attended to daily and others weekly. The following is suggested as a daily program to be followed:
