  1. I was the radio operator and repairman on the American military duty trains running between the Berlin Wall and the Iron Curtain during the Cold War. One night we had a high-speed derailment in East Germany during a heavy snowstorm. That experience will be with me for the length of my years. Thankfully nobody was seriously injured. Derailments are no joke people; it’s a truly scary experience. I wish the injured person at this one a speedy recovery.

  2. When you see the distances that the Russian trains do, there is not so much accidents. Last accident in France was the result of some maintenance economy…and any company workers knew the bad state of the Velizy tracks. Sad…

  3. if its low speed, level ground, and a small train, you have a good chance you can just re-rail it with a small crew, we had it happen once on a tourist railway (we never did “high speeds, all antique equipment. ) but when you add speed, mass (large freight) accidents happen, no mater how many things you put in place. wheels get “hot boxes” (where the bearing in the wheel over heats and disintegrates), idiots put things on the lines, storms blow things on lines, etc. lots of things can happen. Railroads put in place sensors which check for things like this (rock fall sensors, hot box sensors) and all engines have dead man switches , meaning that the engineer has to touch the controls every 30 seconds else the train sounds an alarm, then 30 seconds after that, if nothing happens, they auto break and alert the nearest control tower about it (in case the engineer(s) have had a medical emergency)

    So someone mentioned above about the rails, Modern track “floats” on the road bed, designed to move a tiny fraction when it contracts in cold, or expands in heat, usually using wide road bed, and gentle curves. technically, trains weigh a lot more than most track can handle by itself (especially with old rail/ties) and this weight is distributed by the Ballast ( stones) and the road bed. Rail lines are regularly scanned by maintenance equipment using ultrasonics to find cracks in the rail and welds, they also run “grinder trains”, which has 5-7 units that grind and shape the rail back to to its pre worn shape. They look really cool (see if you can find a video of one).

  4. Whilst working for British rail I witnessed a very slow speed derailment at my depot. A passenger set of 8 cars left the depot and proceeded towards the main line, passing a red light signal. This was normal practice as the driver would wait just past the signal knowing that his relevant signal would soon turn to green.
    This morning though, it didn’t, and on his way to the red light, he’d passed through a set of points set against him (the points can be pushed over by the wheel flange, and no harm is done), the train had stopped on top of the points and his train was now in effect, on two separate lines, as the points had returned to their set position.
    He decided to reverse back and managed to gain a bit of momentum, perhaps to 10mph before a wheelset encountered the points leading the train onto another line.
    Three cars were derailed and severely damaged, Grp doors popped off. the rails were dragged out of position, the points were damaged. The depot was closed for a day and all of the rolling stock trapped. The driver was uninjured, just a very red face.
