Not to mention that the "washout" at an unspecified location somewhere in the general area may have been more in the nature of some embankment erosion that did not affect the actual track.  We just don't know.  Detailed speculation based on ignorance is a foolish waste of time, especially when carried to the extreme we have seen here.

 

  

True.  However, it seems obvious to me that neither the NTSB preliminary report nor the BNSF spokesperson would mention a track washout somewhere else, since that would be irrelevant to this derailment.

I don’t see where BNSF spokesman Andy Williams mentioned or confirmed that tracks were washed out.  Apparently he was asked by a reporter if the engineer knew or should have known that track was washed out, and he had no answer to that question.

Charlie - you should know by now that the only opinions that count here are Bucky's. 

All other opinions are "unsubstantiated claims."

I don't give a fig about this silly, ongoing kid's game between Bucky and several other members.  When he or anyone else makes what I think is a useful observation, I take note.  Otherwise the back nd forth sniping reminds me of junior high school games.  Boring and childish.

Did they see the washout after the derailment? Is it still there or has it been repaired? Did they take photographs of it?

A wash out occurs when flowing water "washes out" the ballast and subgrade material from under the track.  Its pretty easy to find once the water goes down.  If the ballast and subgrade material is 30 or 40 feet out into the field, that's a wash out.

Euclid
Or was the washout visible to the crew as they passed into the area where the derailment would occur? If so, did the crew report feeling any track problem when they ran over the washout? Or did the crew feel a track anomaly as they passed over the area where the derailment would occur, but not see any evidence of a problem?

There is no public report of the crew saying there was a problem or reporting anything to the dispatcher.  Not saying whether there was or wasn't just there hasn't been a report.  The crew may not have seen the washout, the crew may not have felt the washout if it gave way after the engines passed.  Once again we don't have that info.

Euclid
They told us lots of facts about the train. Why not tell us about how they found the washout and where they found it? Is that asking too much?

Why should they?  What difference will it make if they report this afternoon or 6 months from now?

Of course if its truly a washout, where the track structure was compromised by erosion, then that whole "liquifaction" scenario becomes pretty much moot.

Yes, and if it is truly liquefaction where the track structure was compromised by a loss of support, then that whole "washout" scenario becomes pretty much moot. 

When reading the preliminary report, I was at first uncertain as to whether the washing out of track that it referred to was at the Doon derailment site.  Some people here vehemently insisted that the report said the washout was at the derailment site.  I still was not sure.  Then I saw that the news media seemed to widely assume that the report meant that the track had been washed out at the derailment site.  So I decided to adopt that position. 

But now, I see that the news stories have backed off on interpreting the NTSB report as stating that the washout was at the derailment site.  Instead, they just quote the NTSB report directly.  This tells me that like my original position on this, they don’t know what the NTSB report mystery sentence means.  So I too have reverted back to my original position.  That is that the report says that the rain washed out track, but it does not say where that occurred.

Also, BNSF spokesman Andy Williams is quoted responding to a question about whether the engineer knew about the washout or should have knowing about it.  Mr. Williams had no answer.  I have not seen a transcript of that interview, so I do not know if Mr. Williams acknowledged that there had been a washout as the question to him implies.

Taken all together, I see no reason to believe that a washout occurred at the derailment site.  There is no evidence of that.

I dunno. Unless you are using completely different meanings for the words written than the rest of us, I don't see any post that vehemently insisted that the report said the washout was at the derailment site.

Well maybe vehement is a little strong, but I was thinking of you and Mr. Hebdo.  You both seemed to believe that there could be no other meaning to the mystery sentence.  I have since spoken to the NTSB, and as of now, that has been inconclusive.  But maybe they need a little time.  If they did not mean that the washout was at the derailment site, why do you think they mentioned it?

Maybe because it's a potential consideration in the investigation?  That was a preliminary report, after all.  As such, it's going to cast a wide net, especially if they haven't nailed down a "chief suspect."  

Perhaps the intention of the statement was to indicate that washouts (or potential washouts) had been observed in the area, so that's a consideration in the investigation.

As the investigation progresses, the investigators will be ruling out potential causes, from broken rails to broken equipment, to a failed roadbed, to who-knows-what.  Maybe they've already ruled a lot of things out.  We'll get our answer when the final report comes out.

4) The train was operating within its authority.

Just clarity, what "the train was operating in its authority" means is that the train had main track authority for the location at which it was operating, i.e. it wasn't off its route or someplace it wasn't authorized to go.  If a train was authorized to go from Anna to Dora and the derailment happened at Bess, the train would have been operating in it authority.  If a train was authorized from Anna to Dora and the derailment happened at Eve, then it would have been out of its authority.

In or out of authority has no bearing on what restrictions, if any, were in force or what speeds were authorized, it just says the train was where it was supposed to be.

"Sir.. please stop calling us."  ?

It's been fun.  But it isn't much fun anymore.   Signing off for now.

I don't think they care if you contact them.  They actually have a contact  portal for questions and comments from the public, but it is kind of boiler plate.  You can end up talking to someone who is not much help.  I think it is possible to get a very meaningful response, but you have to be persistent.  I have talked to two people who were extremly perceptive and razor sharp.  They could not answer my question but, they said they would find someone who could.  So it is a big process and it takes time.  They also read emails.
