[quote user="edblysard"][quote user="Bucyrus"][quote user="csxengineer98"][quote user="Bucyrus"][quote user="edblysard"]  Watch it again, you can see the opposing train trip the signal system and our signal aspect changes from red over green, (diverging route) to red over red, as it should once someone ocupy the circut, which the opposing train does just as he passes the signal mast on the other side of the switch.[/quote]I thought I was seeing, at first, a green aspect on that signal the first train passed, but when the camera got closer, it looked like red over red.  I did not start/stop to check it out, but just concluded that it was red all along.  Your explanation that it changed by the violation of the oppsing train makes sence.  But even if that signal did go red right in their face, would they not have been required to see it and stop, even if they could not stop short of it?  Don't they have to watch and react to every signal right up to the point where they pass it and can no longer see it?That brings up another question.  Wouldn't the dispatcher see that the first train passed a red board and communicate the error to the crews of both trains?  When the first train got the red signal in their face, did that mean the other train was passing a red board at that moment?  Wouldn't the dispatcher have seen this whole thing unfolding? [/quote]after watching the video many times.. as fast as that all happend..there was NO WAY anything could have been done in time by anyone but the crews.. the meet was "perfict" so to speak for a headon in the middle of the plant.. the signal on the train with the cam went from medium clear to red about 2 seconds befor the locomotive passed it..that is not enought time to stop unless he was going 1mph.. and he was going alittle faster then that.. and as far as the dispatcher seeing it unfolding..he saw it unfold as soon as the system went "out of corrisondance" as the derailing trains destoryed the wireing and track circits that ran the system at that interlocking.. if the train with the cam on it was a few miles away from the plant.. then there might ahve been some time to stop both trains in time but there was nothing anyone could have done to warn anyone in time for this situation.. csx engineer [/quote]I do not know what the conclusions of the investigation were, but I wonder where the train opposing the camera was when they set the brakes.  It raises one other question, but I won't speculate before others comment.  I think it is interesting to understand exactly how these things happen, and what options are available as time runs out.[/quote]I suspect you are wondering why the alerter didn't wake them up...It can be disabled with a breaker in the rear cab wall, in front of the electrical cabinet.You have to have a way to disable it so you can move the locomotive as dead in tow or for maintenance purposes.Get caught with it turned off and your fired outright, no questions allowed nor any argument entertained.Yes, the black box would note the alerter was off...you can be sure both the engineer and conductor, if they survived, won't work in the industry again.[/quote]I am not familar with the alerter, but since you mentioned it, I am curious about what role it might have played.  What I was wondering about in the earlier post was the amount of time between the point where the opposing crew put the brakes into emergency and the point where they ran past the stop signal.
