  1. Also a similar disaster to this happened in Canada, search for the Lac Megantic Train Crash.

  2. LOL!
    Sam Bernardino is NOT a nice little town to raise a family.
    Not even close

  3. I live in San Bernardino, I remember when this happened. I lived a mile from where this happened

  4. if you watch train wreck analysis videos, there is always a missed check. every single time without exception and without fail.

  5. R.i.p

  6. Hey, I have an idea, Don't send Trains over mountains without 100% braking operational.

  7. Most of the day, how’s about floating in shark infested water injured for 4 days and night no food or water and 316 surviving, they all should’ve died off water starvation alone

  8. Insinurated

  9. Well, I guess that guy never fell off a cliff.

  10. I used to live therr

  11. Even with the white profile of this particular train being 30 something percent heavier than what they expected or thought, why were these locomotives and engines allowed to operate with some of them not being 100% operational. This is ridiculous !!!!

  12. I've never been able to watch all of this video documentary and l never will.

  14. Today both BNSF and UP both run longer heavier trains, and do so with only two crew members. Could this happen today? Absolutely.

    Your typical 15 minute video, fleshed out with fat, to be a 50 minute video.
    With no easy way to cut out out the fat.

    GREAT story, should have been done in 20 minutes.

  16. Do trains have maintenance schedules so that if something goes wrong, it does not become disastrous? But here we are.

  17. Don't raise your family in San Bernardino. Trust me.

  18. It shouldn't bend around the corner right after a big hill

  19. I like trains 🚆

    this is the true defonition of a disaster

  21. Wow , and I thought the washer I forgot to put in the transmission was a mistake 🤔☹️

  22. Heh 69 freight cars 4:14

  23. They didn't set all set all retainer valves and the air

  24. Did they have a terminal air test before they left

  25. Dispatcher was on cig break

  26. Sonny of the beach

  27. There's your problem. Weight is measured in pounds. Kilos are a lot heavier.
    Then you've got to calculate the train speed in furlongs per fortnight or something.
    It's unnecessarily complicated.

  28. this video sucks

  29. I've just finished my engine and air course yesterday in Geelong Australia and am now starting out as a driver under instruction. We learnt just a few days ago that when your train is in full dynamic with full air brake applied and you are maintaining a constant speed downgrade, you are out of control as you have no more braking power to deliver and an emergency call must be made. We also learnt that a full service application of air brakes is more effective than an emergency application in this situation as the power knock out switch will not be activated and the dynamic brake will remain engaged. We all learn from these terrible accidents, most of the rules arise from incidents such as these.

  30. 110 miles per hour!! Wow! Every safety precaution should have triple checks.
