  1. There was a similar accident in Granville Sydney, a train derailed hit a bridge support, the bridge collapsed on the train killing 83 people seriously injuring dozens.
    It was transformational for Sydney, Government had revues of structures over rail lines, a number of dangerous structures had to be rectified, a massive program of installation of modern all welded track and concrete sleepers which took over 25 years, points were replaced and rolling stock modernised.
    The three decades following WW2 Government had severely cut corners in maintenance and modernisation.
    After a decade a new conservative Government cane to power and again started to cut corners, there was another serious accident in 1999 killing 7, the Government was immediately voted out at an election a few months later, this ended all corner cutting in funding of maintenance and new safety technology.

  2. They didn't properly examine the ICE wheels anymore because the crappy examination equipment caused too many false positives.

    It isn't that they didn't know of the risk. It is that they didn't take it seriously enough. Sadly, this is something that happens far too often.

  3. The ice train was 5-9 years old at the time of crash. You don’t seem to hear of new trains having tragic accidents nowadays resulting in lots of death. Feels like a different era of travel.

  4. Japan's bullet trains never used articulated bogies and still maintain zero passenger fatalities. The trick is to avoid crashes in the first place.

  5. I understand getting rid of the emergency brake thats available to passengers, but that feels like a new type of dangerous.
    I had an uncle who as a teen in NYC, would board trains by jumping onto the connecting segment between cars as the train was leaving the station, because he was a dumb teenager. As you can expect this didn't end well, and one time he ended up with his leg wedged between the train and the platform. And as the train was picking up speed he was being dragged along. It was a passenger who spotted him, and pulled the emergency break that saved at the very least his leg, if not his life.
    It could also be argued that the German derailment could have been avoided, if the passengers had had access to an emergency brake that could have stopped the train when the car floor was breached by the chunk of metal 5 km before the accident occured.

  6. In the accident at Gare De Leon, I am confused why draining the air pressure would work. That is exactly opposite of how almost all units I know of function, in that it should never be Fail=Open. Even the much smaller airbrakes on tractor-trailer cargo trucks are the reverse of that. The air pressure in the airbrakes is countering a structural brake which wants to be closed. In the French train this was held shut by the second air system, the one the driver depressured, but this means that a pressure loss in the car would leave the brakes disarmed. The driver demonstrated that, and the fact he knew how to do this concerns me even more because it means that he had done so at other times. In a truck brake, a powerful return spring means that if you depressurize the airbrake, the truck STOPS. The return spring is applying constant pressure with the goal of closing the brake, and only the air pressure provided by the semi-tractor holds the brakes open. If the system is purged, as the driver did in this case, the brakes simply will not move until pressure is returned.

  7. Ever notice. that The French – who lost 3 Wars in the 20th Century – somehow nowadays think they are good with High Tech – – (The Airbus Autopilot has caused many Crashes)

  8. The Class 390 crash only ended up in one death due to shock. The train itself was actually pretty safe.

    BS thumbnail as always.

  9. See You Brits that started this with Stevenson. Come on you Brits including you Brits with Millions in the Bank. Lets rise again and catch up with the French. Big Up UK XXX

  10. You missed the incident near my house in Desford in 1833. A train racing along at 4mph collided with a horse and cart carrying eggs and butter to Leicester Market. The tracks went straight across the lane as crossings hadn't been invented yet. Mr George Stephenson the engineer of the Leicester-Swannington railway asked a musical instrument maker in Duke St, Leicester to modify a horn such that they could operate it from the footplate. After that all trains were fitted with a horn or whistle.

  11. i will never go in a train that can be fast like this. only if you tired of life. i like the old trains. you can watch the outside. and time is no aspect for me when i am travelling. i dont know why people would be faster and faster with almost everything . . . or with other words: "time is on my side".

  12. Computer controlled high speed trains? Sounds like something that hackers will try to attack. How will they protect against nefarious lunatics trying to take over control of these trains?

  13. It sure could use voice over and get rid of the annoying text/subtitles when people speak in different languages. I watch these to learn something, and having to read while watching is distracting.

  14. The 1989 German ICE train crash. So if we are to believe this stupid non technical programme, none of the passengers thought to pull the communication cord, which automatically applies the train brakes, and stops the train ???? And Christian Wolmer is not a rail engineer but a journalist for a non technical train spotter magazine !!! The whole technical report by the German Railways, revealing the cause, was published in the British technical rail magazine "Modern Railways" published by Ian Allen and available in any W.H.Smiths, around 6-8 months after the crash.

  15. I hate documentaries which depend on shilling for corporations and producers who know little about their subjects. Dynamic braking, described in the Parisian accident portion of this video, has been a standard feature of electric railroads since their early days over a century ago. Relying solely on them for braking has usually been considered impractical and risky. What happens if the power fails? Probably the best safety feature any vehicle can have is a sensory system which detects unusual activity such as excess heat or vibration in the undercarriage or motors. In the Parisian case I don't know why the station authorities didn't announce an evacuation of all the trains in the station.

  16. I know five km isn't far but I would have thought it was enough to have alerted the driver to the problem. Isn't there a way to stop that train? An emergency stop? Pardon my ignorance but I haven't been on a train in more than fifty years.

  17. What I don't understand is why must a train travel at 500 mph or faster, where to people need to be in such a almighty hurry. Then when they crash it's a nightmare & (X) number of people
    are either seriously hurt or killed just because of the trains speed like a rocket ship.

  18. I still think that the lady who pulled the emergency break should've been charged, her entitled attitude resulted in many people dying all so that she wouldn't miss her stop.
