The old thread hadn't autolocked, but it was near 900 posts, so I'll start a new one. And here's a good start that does not involve trains. Normalization of deviance. David Sitting on my butt while others boldly go, Waiting for a message from a small furry creature from Alpha Centauri. |

Very interesting story David. In flight test we call this "learning to ignore what doesn't kill you right away". Humans are just too flexible, they will quickly adapt to anything that doesn't offer an immediate dissuader. You skip check lists, you ignore buzzers and lights, and if you are still alive it is so much easier to repeat the action the next time. The most dangerous part on any aircraft is the sloppy link between the control stick and the throttle. The automation and drone crowds, BTW, supports this theory 100%. Computers don't have this problem. |

I've had experience of a crash like that. It happened about 1/2 a mile from where we lived, assisted in bringing survivors to shore. Northern waters are still very cold in July. https://en.wikipedia.org/wiki/Dan-Air_Flight_0034 |

This link actually came to my attention via the museum volunteers Facebook group. The same kind of mentality can easily happen on railroads, all the more with the trained amateurs that most of us are. One of the guys who trained me on the streetcar gave me his checklist for it. (I added an item.) I wrote my own list for being coach conductor. Need someone to go over it and see if I missed anything. The thing I worry most about as conductor is that I'm forgetting something important.

My immediate reaction was that it applied to much more than just transportation. To be continued and expanded in the BOINC/Politics thread. |

You're right Richard. There is a HUGE debate going on in Canada about doctors (especially surgeons) being required to use check lists by hospital management. Quite a few doctors argue that this somehow cheapens their careers. The fact that it occasionally saves lives appears to be of secondary importance to them. I run into this mentality quite regularly when investigating machinery accidents. I've come to call these people "too cool for rules". I often hose their remains out of the works before starting my investigation. (Feel free to move this post to Politics if needed. I never go there any more.) |

2 killed in crash involving Metra train in southwest suburb; 3 others injured HOMETOWN, Ill. —Authorities say two people have now died as a result of a crash involving a car and a Metra train. |

2 killed in crash involving Metra train in southwest suburb; 3 others injured Ordinarily, I'd say something about people being stupid about trains, but given the weather yesterday I won't. Still, not having the kid in a proper child seat is stupid. David Sitting on my butt while others boldly go, Waiting for a message from a small furry creature from Alpha Centauri. |

Five "adults" plus a kid. I'd guess the kid was on one of the adults laps and became a canonball. So sad for all the families concerned. Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

Most of the time this thread is about accidents. However there is another side to "safety" - arriving safely at one's destination, as this lady has done http://www.bbc.co.uk/news/uk-35271182 Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

Now I've heard them all :-) Our morning traffic reports sometimes have sunshine delays, when it's lined up just right for drivers on one expressway or another. I have also heard of train crews not being able to see signals because of the sun either right on it or right behind it. There have even been a few wrecks because of it.

TBH it can be a problem. |

The news story makes it sound like it was the trains fault for hitting the truck. Truck driver dead after passenger train, 18-wheeler collide in Mesquite The driver of a rock hauler died Thursday afternoon when his vehicle was hit by a passenger train in Mesquite. |

Amtrak 383 hit a BNSF welding truck Saturday night in the next town east of me. I downloaded the audio archive recordings from my Broadcastify feed. I clearly hear 383's engineer say he was crossing over from 1 to 2 with a diverging clear signal, and hit the truck, which was in the foul. I don't really want to speculate on fault here, but two obvious possibilities spring to mind: either the dispatcher gave the welders improper authority, or the welders violated the limits of their authority. Beyond that, I will wait for the investigation's conclusion. There may be other explanations I haven't thought of. I haven't listened to all the audio yet, so I don't know if it will offer me any additional clues (like the dispatcher issuing the track authority to the welders, but that could have been done by phone).

Amtrak 383 hit a BNSF welding truck Saturday night in the next town east of me. Several other possibilities exist. Dispatcher giving Amtrak improper authority. Welders or Amtrak violating a time constraint. Read-back error. (the dispatcher not hearing the clearance read back being different than his order) Signage error, or vandalism, mile marker or foul point. Signal error showing the switch alignment incorrectly. Of course there is also deliberate act. Dispatch errors might be compounded by a shift change, with different dispatchers giving conflicting orders, although in this day and age I would like to think BNSF has a computer program looking over the orders for obvious conflicts. Slips of paper can get lost or overlooked. All speculation of course. |

Amtrak 383 hit a BNSF welding truck Saturday night in the next town east of me. Amtrak's authority was conveyed by the diverging clear signal he (said he) had. The investigators will of course have access to the video camera in the cab, which would easily show if the engineer was lying about the signal. Assuming he was not lying, the signal corresponded to the switch position. I doubt there was a dispatcher shift change near that time. I think the shift is 3-11, and the dispatcher I heard on the recording was different than the one I heard live while I was driving home after 11. (I suppose the one on duty could have been relieved after the crash.) Given the time, weather conditions, and amount of other rail traffic at the time, vandalism is also unlikely. Welders violating a time limit is a possibility, as is a read-back error. I need to listen to more of the audio files. (Presumably, the investigators will listen to the dispatcher's audio recordings, although if they come and ask me, I will provide mine (but they'd be more likely to subpoena them directly from broadcastify.com).)

Given the time, weather conditions, and amount of other rail traffic at the time, vandalism is also unlikely.How often is it checked for? By that I mean if someone stole a milepost sign how fast would it get discovered and replaced? And if so did it get replaced at the proper spot! Welders violating a time limit is a possibility, as is a read-back error. I need to listen to more of the audio files. (Presumably, the investigators will listen to the dispatcher's audio recordings, although if they come and ask me, I will provide mine (but they'd be more likely to subpoena them directly from broadcastify.com).)Doesn't BNSF record? Does the cab recording include radio traffic? If orders are given by telephone, are they recorded? Only reason for them to look to a third party for the radio traffic is if the recordings don't match, to see if there was interference or equipment failure. There is a lot to an investigation. You must not assume even the obvious. You have to verify every fact and that every item is functioning as expected. |
