I have long underestand that the standard warning for persons or any live thing in danger of an approaching train is a series of short blasts. I have heard such on the Rochelle camera thread, and I saw the necessity of such while waiting for #6 in Sacramento--two or three men who were too far from me for me to shout at them were standing within the danger area on the platform and the engineer was blowing that single, which they, of course, did not comprehend.
Any railroad employee should comprehend that signal. Was the engineer of the approaching train so taken by surprise at seeing the men on the track that he failed to react as he should?

What we need is a simple rule, or even a simple convention.
If you're approaching a perceived target 'from behind' use a series of horn blasts, or a coded signal, instead of a single long blare. I thought there was already a convention to use something like the MTA's long-short repeated combination whenever passing through a MOW or 'known restriction' zone.
The point being to disambiguate the signal used by one engine in a 'meet' from the other's, in some fashion that can be reduced to a rule.
That is a classic case of not seeing a train approaching from behind because of being distracted by a train observed approaching from ahead. Without being aware of it, people lose sight of the fact that their normal situational awareness is greatly diminished by a train they are already aware of. People become unaware of the fact that they are unaware. They can see and hear fine, but not realize that their hearing cannot distinguish source direction. In my opinion, this is the great hidden danger of a double track line. In a situation where no train is approaching, a person feels totally protected by their sense of hearing and sight. But if two trains are approaching, source direction detection of hearing can be easily lost.

Never too old to have a happy childhood!
We had a number of accidents on station platforms were people standing too close to the edge were killed or strollers sucked in by passing trains. These trains were traveling at around 75 to 100 mph.
Today danger zones are marked on the platforms: http://www.bahnbilder.de/1024/bahnsteig-2-3-wittlich-hbf-632108.jpgRegards, Volker
Obviously you have never been very close to a fast moving train. The windblast from the lead unit or control cab is significant and could easily lead to a momentary loss of balance. That in a situation with absolutely no margin for error can easily prove deadly. The recommendation posted earlier to "hit the dirt" is well worth remembering, since that puts you in a stable position and also with additional clearance. Of course, in 3rd rail territory, maybe not.
I do agree that it is plausible they never saw it coming. The cab video should answer that question.
Even with a train approaching fast and close, getting into the clear would not have required more than a split second, and would have been intuitive to experienced railroaders. I doubt that air movement created by the train played a role. The fact that they did not get into the clear is evidence that they never saw the train that hit them.
One good possible reason for that is that, with both trains blowing horn warnings, the warnings were heard together and not as two individual warnings from two different trains.
It is reported that they were walking with their backs to the train that hit them. So they could have seen the other train approaching them, and attributed both train warnings only to the train they saw coming toward them.
This type of ironic outcome from horn or whistle warnings causing the opposite of the intended effect has happened before, and I suspect quite often. If so, it actually does seem worthy of being labeled as a “perfect storm” in that it requires two trains approaching simultaneously and each giving warnings that obscure the warning of the other.
Here is an historical example of this type of accident:
June 1890
23rd, on New York, New Haven & Hartford, at South Lyme, Conn., butting collision between two gravel trains. The engine of one of the trains was pushing the caboose. One laborer was killed and three injured. It appears that the conductors of these trains made meeting points verbally upon their own responsibility, which a coroner’s verdict says was “without the knowledge of the railroad company.” The coroner’s verdict also says that each engineer on approaching the curve where the collision occurred blew a long blast of the whistle, and that very likely these signals were simultaneous, so that neither heard the whistle of the other.
quote user="daveklepper"]Possibly this freight crew had never become accustomed to anything like the close track spacing that is particular to this location (and others in the NEC and commuter railroads in the New York area). They assumed that walking in the center of space between the two tracks was safe, which it was not, since there was insufficient clearance. And yes, if they had "hit the dirt" the overhang of the trains would probably have passed over them.[/quote]
The Conductor had been qualified for about 2.5 years and had worked the Cumberland/Baltimore Pool for most of that time. There is no way to tell how many times (if ever) he was on the ground at F Tower. However, he had been through F Tower on hundreds of trips.

The " hit the dirt " appears to be good advice even if raining.
So then there is no location within this grouping of four tracks that a person could occupy while being considered safe from the nearest passing train. That sounds like a death trap that would require positive protection.
Any conflict is purely in your mind. "On the track" will include on the ballast section, which likely extends across the full width of all the tracks. And that puts them in a dangerous zone, as sadly was shown in this case.
Others have mentioned the wind blast and possible suction. The other factor will be the disorientation caused by a fast moving train right beside you. I haven't heard if they were hit by the front of the train, or staggered into the side.
EuclidWhat is the source of this information in the Newswire story, and why are the two statements in apparent conflict with each other? …the conductor and conductor trainee of CSX intermodal train Q137 were walking in the space between the CSX two-track main line and Amtrak's Northeast Corridor. Both engineers stated they started blowing their horns when they saw the CSX employees on the track, the report says.

schlimm RME they were most certainly not walking on the far Amtrak main facing that train, and they did not walk into the gauge of the near Amtrak main while overconcentrating on the oncoming train. While the former seems likely, the latter is unknown. If anything, it is likely they did stray into the gauge of the near Amtrak main. However, as BALT says, we should wait for the forward-facing Amtrak locomotive video.

Pending the video, I would opine that it is possible that they were close enough (but not on, or within the "kill zone") to the Amtrak rails to be thrown off balance on the unsure surface of the ballast - ie, they fell into the train. As has been noted, there is a bit of a pressure wave involved with a train doing near 80 MPH. And there's not a lot of room between the tracks.

RMEthey were most certainly not walking on the far Amtrak main facing that train, and they did not walk into the gauge of the near Amtrak main while overconcentrating on the oncoming train.
The direction they were headed while walking was the same direction as the Amtrak train was traveling. So it is likely that they were walking with their backs toward the approaching Amtrak train. But how can you be so confident in knowing where they were walking?
It seems to me that it was possible that they were walking on the track where the Amtrak train was approaching; or stepped onto that track to clear the other track where a train was approaching them from the front. Why do you rule out those two possibilities?
tree68 Euclid I would say that for a perfect storm to be possible there has to be a lack of safe procedure, or a rules violation. How soon they forget.

I have not forgotten that. Offering a rules violation as one possiblity is hardly the same thing as judging that a rules violation did ocurr, as RME accused me of doing.
Until such time as NTSB or Amtrak release video from Amtrak Train #175 there can be no answers to the questions of what the CSX crew was actually doing. All we are doing is speculating on speculation only knowing the final outcome.
EuclidI would say that for a perfect storm to be possible there has to be a lack of safe procedure, or a rules violation.
RMEBut I do not think it is fair or just to judge there was a rules violation, in this extraordinary circumstance, just because the two have died. I doubt he can convince you out of having a prejudicial opinion, though, no matter what the rules actually say.

Oh please. I suggest you go back and carefully read what I said before you jump to wild conclusions about me unfairly judging or having prejudicial opinions. Nowhere have I judged that there was a rules violation. And I have no opinion at all about this, let alone a prejudicial one.
I am just trying to puzzle out how this accident happened. The idea of a “perfect storm” being the cause strikes me as weird in this case of a specific work procedure with no intervening “act of god” type factors. There is a rule requiring one to expect trains any time and any direction on any track. I don’t know if there is any requirement to walk in certain directions on a track. I don’t see the analogy of that to walking on roads because there you can anticipate the traffic direction. On a railroad track, you cannot anticipate traffic direction. Reasonable safety would require looking back very frequently. Even that is imperfect where the potential for relatively quiet, high speed trains run. It seems the best protection would be to not walk on the track at all.
I do not know the track layout in this area. Is it impossible to perform the work they were doing without fouling a live track?
You would, wouldn't you? And perhaps there was; I don't know there wasn't.
The issue here is that most of the elements of the 'perfect storm' were circumstantial, if decidedly very, very unlucky. Had the two men walked the 'active' side of the cut first, they would have been facing the right way in traffic the whole way down to the crossover, and come back up the other side of the cut to the power on a thoroughly unoccupied track. But to my knowledge there is no "rule" or even "safety procedure" that mandates always facing the expected direction of movement when walking adjacent to a track. Perhaps there should be; essentially there is for pedestrians walking next to road traffic. But I do not think it is fair or just to judge there was a rules violation, in this extraordinary circumstance, just because the two have died.
But we have BaltACD still commenting in this thread, who knows the relevant CSX rules and safety procedures better than you or I ever will. Perhaps he can provide you with details of how this was their fault through wilful ignorance or inattention to particular rules. I doubt he can convince you out of having a prejudicial opinion, though, no matter what the rules actually say.
BaltACDCrew did most of their inspection walking on or about CSX #2 track which the head end of their train had blocked. The great unknown is why their heads weren't on a step by step swivel when they got to the location where they had to walk between the CSX & Amtrak Mains.
Perhaps one should have tried walking backwards (difficult and dangerous) so as to see an oncoming Amtrak train? Even if they heard or saw the approaching train, escape in time would be ddifficult. Perhaps the inspection should have been halted/postponed at the point where the engine and those cars were on the track adjoining Amtrak?
RME I think it was more an unlucky 'perfect storm' of bad circumstances that killed them, more than any obvious lack of safe procedure even for a brief time.
I would say that for a perfect storm to be possible there has to be a lack of safe procedure, or a rules violation.
EuclidIt sounds like the perfect setup for the scenario I refer to above.
Except that it's almost the perfect opposite: they were most certainly not walking on the far Amtrak main facing that train, and they did not walk into the gauge of the near Amtrak main while overconcentrating on the oncoming train. We've already commented on the issue with both Amtrak trains simultaneously sounding their horns, probably continually in panic and horror, and the ambient noise and sound reflections from the adjacent train and its power. The issues that I think need to be resolved is how far over toward the Amtrak side of the ballast 'valley' they were walking when the following train overtook them, and how they were brought in contact with the train; personally I think they were caught off-guard,stiffened in surprise or staggered and were then pulled in by the initial 'suction' behind the bow wave of displaced air, rather than being 'hit' by some part of the front of the train.
I do strongly suspect they were being careful not to walk on an adjacent main, or even in the clearance 'gauge' area, as your analogy's wording would appear to suggest. They might have been fully observant of where to go and what to do in normal four-track clearances. I think it was more an unlucky 'perfect storm' of bad circumstances that killed them, more than any obvious lack of safe procedure even for a brief time.
I have seen reports of train strike fatalities of people occupying one track of a double track. The person’s attention is drawn to a train approaching them from the front on the same track they are walking on. So they step over to the other track to get out of the path of the approaching train. But there is also a train approaching from behind them on that second track. They step in front of that train and get hit because they never thought to look back with the distraction of getting out of the path of the train to their front. Both trains are making plenty of noise, but the person assumes it is all coming from the train approaching them.
In the case of this accident, we are told that two opposing trains simultaneously converged on the location of the two trainmen. Both trains sounded their horns. It sounds like the perfect setup for the scenario I refer to above.
schlimmThe two ROWs are parallel and very close. They may have been on the Amtrak property without realizing it. Given the much greater frequency of high speed Amtrak trains, shouldn't they be instructed to walk on the other side of their train on the CSX track?
Defect Detector initiated inspections require inspections on both sides of the cars. My understanding is they inspected from the engines back as far as necessary on the side of the train away from Amtrak. Their return to the engines was accomplished on the side adjacent to Amtrak. Train they were inspecting had been operating on CSX #1 track, furthest from Amtrak, the CSX engines and 'maybe' two cars were stopped within the limits of the F Tower control point interlocking on CSX #2 track, the track closest to Amtrak as they had operated through the crossovers at F Tower. Crew did most of their inspection walking on or about CSX #2 track which the head end of their train had blocked.
The great unknown is why their heads weren't on a step by step swivel when they got to the location where they had to walk between the CSX & Amtrak Mains.

tree68 73 MPH comes out to about 110 FPS - or around one and a half IM cars per second. Add in the other factors already mentioned and the crew had little time to react. Given poor footing and the distance to their train, apart from dropping to the ground immediately, they were sitting ducks.
