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.
6/
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.😈
Homicide statistics since the early 1960s are not comparable to earlier periods because medical advances have turned many fatal injuries into survivable ones.
I'm tempted to say the difference between military flag ranks who are competent at 2026 peer to peer warfare, and those who are not, is the understanding and application of attritional loss curves to combat loss rates, electronic warfare and logistics.
The set of curves I had an AI produce for me above have been used for air warfare many times starting at the end of WW2, in the USSBS after WW2 and by many classic RAND airpower studies from the 1950's to 1980's.

All post 9/11/2001 Western flag ranks are counter-insurgency (COIN) trained & experienced.
They have no gut feel at all to statistical attrition models at all.
These "COIN-head" flags may prove to be highly resistant to changing this. Which is required to deal with drones.
2/
The effectiveness of drones is directly affected by the electronic warfare competence of the drone users.
The fact that the US Army defenestrated every EW practitioner in the 2000's and has compete "EW virgins" as flag rank leadership means it will fail with mass casualties in its first major drone war combat.

3. The shooter arrived at the hotel the day before the event.😯
4. TSA rules require firearms to be transported in checked baggage, unloaded, and locked in a hard-sided container, declared to the airline at check-in.

5. Local DC law requires firearms in vehicles to be inaccessible from the passenger compartment and unloaded.
6. Washington DC is not a "safe passage" jurisdiction for non-residents without a license. The shooter lacked this license.

USN flag ranks & their staffers have been fighting the idea of distant economic blockade of China tooth an nail as a response to China invading Taiwan for 30 years.
They really don't want a recent precedent of a successful blockade...
...to prevent their Carrier fleet Pickett's charge into the South China Sea.
Specifically distant blockade as a strategy against China makes having/regaining 100 Cold War era

...frigates and destroyer tenders supporting them on distant blockade stations outside the 2nd Island chain, "budget relevant" for a military strategy of conducting three years of blockade enforcement.
