EuclidI am surprised that these bearings can be re-manufactured. I wonder if they have manufacturing dates and serial numbers. I also wonder if the car that had the bearing failure at East Palestine is equipped other bearings that have the same history as the one that failed. If the car does have bearings with the same history as the one that failed, they should all be removed and analyzed.
And, one must ask "what advantage does a remanufactured component usually offer, that a completely new unit does not?" $$$

TTCI R&D, RAILWAY AGE NOVEMBER 2021 ISSUE: Roller bearing reconditioning is a common practice in the railroad industry, with 90% of the bearings in revenue service having been through the reconditioning process.

You people are ignoring what is likely the most important factor in these 'remanufactured' bearings -- their material and quality make them "500,000" mile or better MTBF... but even multiwear wheels last only a fraction of that, and the bearing components must usually be disassembled to replace the wheels on the axles.
So save the Earl Scheib quality and Asian schadenfreude cracks until we have demonstrated proof of such practices in the industry -- not sayin, after the loose-wheels-on-new-cars fiasco, that there aren't.

I would think that the market for reman bearings and axles would nominally be for equipment that IS NOT going to be used in Interchange service. ie. short lines and historic operations on equipment that WILL NOT be going off line.
Such carriers can be willing to 'roll the dice' on such reman components knowing that they will not be subject to either high speed or high mileage uses.
Never too old to have a happy childhood!

Some people are acrobatic in trying to paint the cause of this accident as the railroads being cheap.
An "expensive model collector"
Do you actually know what is involved in either the fabrication or reconstruction of an AP bearing? These are parts that pass at least equal NDT testing to new manufacture, with hundreds of thousands of miles' worth of nominal life on them, and are installed with no less care than new components on the axle ends. Where, then, is the perceived 'unsuitability' for another wheel's worth of interchange wear?
Did you think they pulled bearing rollers out of a bucket and stuck them into a grease-filled cage putting a bearing back together?

In my perusal of the various NTSB reports that have been published, there is repeated reference to the hot bearing on the 23rd car in the train, however, I have not been able to ascertain the car initial and number of the 23rd car. Without knowing the ownership of the car, making any assertions to 'cheap' are way out of line.

Where I'm worried stuff will be found in the woodwork is with the equivalent of places that forge, or pretend, to have proper procedures and certification for highly-stressed components that supposedly have anticipated service life well beyond expectations in service. I suspect that it is difficult to eyeball, say, a roller, and be able to determine whether it is developing internal stress raisers or inclusions leading to face spalling... 150,000 miles of rolling after being re-included in a bearing structure.
What is still 'yet to be determined' is whether lenient track-geometry or flat-wheel standards are leading these components to develop cumulative damage faster, even though they were suitable-for-purpose when installed. The 1998 catastrophic-damage-in-10-miles spalling was both massive and pre-existing when the test bearing was made up. But that level of damage, if developed suddenly in a working bearing, would have the additional damage of the debris in addition to the tribology faillure contributing...
OvermodBut that level of damage, if developed suddenly in a working bearing, would have the additional damage of the debris in addition to the tribology failure contributing...
This is why I look at the possibility of a single roller essentially disintegrating as a possibility. The pieces of that one roller could cause massive destruction of the rest of the bearing.
Note in my linked source that rebuilt bearings are actually quite common - to the extent that most of the cars on the railroad may well have remanufactured bearings, railroad owned and privately owned.
I'm pretty sure that there is a mechanism in place for whatever railroad a car happens to be on to be reimbursed for necessary repairs. Thus the car in question might have been repaired by, say, UP, from their stock of wheels if the car had a condemnable flat wheel.
EuclidThere has been other discussion and controversy on-line about the question who formulated and executed the decision to do the controlled burn. Notice is says that NS did this. I have yet to see any references indicating whether or not the regulators approved of the vent/burn treatment of the five tank cars of vinyl chloride, either before it was done, or after it was done.
My guess is that the incident commander (often the fire chief) with input from environmental engineers and the RR, would have approved it as the best alternative. This was done to mitigate an explosive situation. The point is that it was still NS's accident/spill.
Overmod(And I say that as a confirmed and very satisfied perpetual customer on the yard at Pull-A-Part on Farrisview here...)
Yes, I've had considerable good fortune at the self-serve salvage yards as well. But there is ONLY one reason I use such places.
Same logic would apply to "factory reconditioned" warez, as well.
One would think that with all the emphasis we've heard about efforts to remove rolling stock from inventory the past decade or so, that there would be a considerable stockpile of used bearings awaiting reconditioning?

In the legal action announced in the first post here, the EPA does say that the controlled burn added five loaded cars of vinyl chloride to the “release,” a term that I assume refers to the general chemical spillage of the derailment, as opposed to the release of smoke during the controlled burn. It also says that it was the NS that vented and burned the five tank cars. I must conclude that if NS did not make the decision to vent and burn the five cars, they surely must know who did make that decision.
The ONLY real issue that makes East Palestine other than most other 'serious' derailments is the implementation of the botched "controlled release". (I will address the main-line remediation, which to me is a completely different issue and concern, later.)
There are to me very clear, and ongoing, attempts at a 'narrative' that pins the environmental vinyl-chloride catastrophe on NS. To the extent -- and it may be considerable -- that this interferes in genuine fact finding and assessment of responsibility for controlled demolition of all five cars simultaneously (which, we must not forget, was carefully described in detail many hours before it was implemented), such a narrative in and of itself is reprehensible and should be viewed and treated for what it is.
That is not at all to 'spin around' that the actual people involved in directing and conducting the burn should be held morally and financially responsible for the problems it has caused, and this should not be 'excused away' simply by using deep-pockets litigation (which will almost certainly be how the costs wind up being paid).
It remains to be seen what the nature of attempts at containment of the vinyl chloride were -- I remember seeing news reports that 'containment' efforts, probably including berming, barriers and drainage to catch basins, but again, this is something a fair report will include and discuss. To some extent this would preclude released chemicals from inclusion in the grade and subgrade, but I personally doubt that it would prevent effective contamination to levels that would, in fact, require subsequent mass excavation and abatement (probably via portable pyrolysis on that scale...
BUT at a time and on a schedule that would permit NS to construct the required shooflies, bypasses, shoring, rerouting, etc. to keep at least critical traffic moving in the 'lanes' served by that line. To me, there is no contradiction between NS doing heavy regrading to restore working track geometry ASAP and NS subsequently acting to remove all sources of 'trapped' contamination within their right-of-way. (Something that should be in the docket, eventually, is EPA assessment of how the release from the ROW would worsen over time, and how the cost and scope for this piece of the remediation effort would increase over time. But I distinguish the delay necessary to organize and implement traffic continuation from 'delay' in stonewalling or in acknowledging that full remediation will have to be done, and done as 'timely' as reasonable. And as yet I haven't seen any credible claim by NS that they just rebuilt the main expediently to pretend business as usual, or to claim the residual contamination was 'unimportant' because quickly built over to reopen for traffic.

Or, to paraphrase the old adage in Balt's context: It's a wise child that knows its own failure.

Last I heard it was an NS train operating on NS infrastructure.

THAT defeats any whining that "it's all Norfolk Southern's fault because their train came off the rails".
Get with the actual picture, not what people are trying to spin you into. It was the planned response, not the train wreck, that has caused most of the ecological disaster. Wait to see who's to blame for that before judging.
Yanno? there is just something about NS dragging that sparkler show 20+ miles through the countryside leading up to the incident, that kinda defeats arguments seeking to hold them less than liable.
Bad decisions made during attempts at mitigation might precipitate additional liability for third parties, but that in no way relieves NS of the responsibility to conduct it's affairs properly.\
Perhaps had the sparkler show lit up track side overgrowth, NIMBYs might have reported it, prior to reaching the disaster it ultimately became?
LOL, let NS sue said third parties to recover the damages caused through their mismanagement?

What the accident response ought to be about was reducing the space between measurements, adding more sensor fusion, providing more intelligent (and realtime) analysis of trending conditions that might produce derailment, and potentially bringing in more direct and sensible ways of communicating a catastrophic failure to a train crew... a failure that would NOT have been detectible by any of the increased inspection that is planned to be made a mandate, or for that matter by any crew riding in a caboose. While there's only an idiotic response from Congress so far, I have full faith that relatively quick action to reduce detector spacing to 'what would have picked this up if it were only a bearing failure' will be made, and that AAR will be looking at ways that this can be done with the appropriate technology, cost-minimized through intelligent design and OTS adaptation rather than 'peddled by the lowest bidder'.
... attempts at mitigation might precipitate additional liability for third parties, but that in no way relieves NS of the responsibility to conduct its affairs properly.
NS is on the hook for the full cost of remediation of the accident, no matter how generated. Presumably they were self-insured for this kind of accident, so there will be no convenient limitation on what they'll eventually have to pay. We could speculate on whether some 'fix will be in' regarding what actually gets paid out after appeals and whatever, but I don't particularly think the outcome would be 'better' for NS than it was for the Elizabeth Jones catastrophe... and that's before all the strict-scrutiny pile-on that's already coming, whether it turns out to be functionally relevant to this or not.
The point remains that a great deal of 'additional cost', that we all can stipulate NS is on the hook for legally, was potentially provided not only by threatening NS but by removing any ability to handle the situation more effectively. I can think of numerous reasons why this is not particularly tolerable as an 'excuse to blast NS for some deficiency or other in their safety culture'... until proven. And you can't prove it at this point.
Perhaps had the sparkler show lit up trackside overgrowth, NIMBYs might have reported it, prior to reaching the disaster it ultimately became?
The issue here is to DESIGN and then IMPLEMENT policies and procedures that will help reduce actual problems like this, without introducing hundreds of thousands of hours and other easily-predictable accidents from false positives or improper responses. And to do so, if necessary, in ways that highlight any actual underlying issues with bearings, or responses to issues with bearings, that turn out to be... well, I suppose you have no concept of statutory immunity, either, but it applies to NS if they have defective bearings not directly related to contributory negligence, which unfortunately remains to be proven and I suspect will be remarkably resistant to effectively proving.
The greater issue that has to be addressed here is precisely the matter of incident command that increases public risk out of the control of the entity suffering the accident. Along with this issue comes the much more relevant one of implementing quick and positive command, control, communications and intelligence (which prospectively ties into rapid processing of and response to, for example, streamed video from random cell phones or Ring-monitored surveillance devices [there are already cases about the 'right' of public responders to the full recorded data from those systems].
But these aren't things we're likely going to see from the congeries of sources all too gleeful to talk about how NS owes everybody for everything in this derailment, whether or not it's actually something NS isn't already acknowledging as its financial responsibility regardless of any sort of third-party 'subrogation'. And it isn't something I expect to see from the kind of grandstanding evidenced by things like Buttegieg's letter, for which there is no actual excuse grounded in fact or truth.
