- innocenat 7y agoDoesn't work if the train caught fire or something.
- netsharc 7y agoBut if the track is distrupted (a tree falls on it, or somehow it's just damaged), the train would have to stop right there and then. Maybe they can make something so the train can grip the ground/tracks so it just doesn't fall off when the forces are no longer acting on it.
- majewsky 7y agoThe tracks are not fixed to the ground. If a train grips the tracks in order not to fall over, it will probably still fall over and also rip the tracks out of the railbed as it does so.
- netsharc 7y agoTrue, as we've learned in this article. I guess it will have to grip to something else. But in the theoretical banking the original comment was talking about (let's say 30 degrees), the track would probably have to be secured to the surface... Well, how heavy is a bullet train, where is its center of gravity, and how much banking does it need if it wants to travel, say, 300 km/h in a (how sharp?) a curve?
- bobthepanda 7y agoKeep in mind that banking is only comfortable if you are traveling at the correct speed. There are a whole host of reasons why a train may not travel at maximum speed for a given segment, and the rail line still needs to be reasonably comfortable at all of those.
- m4rtink 7y agoThis is not always true, most of Shinkansen track is concrete slab track, which is effectively fixed to the ground. And they actually do have special anti derailment guides build into the track to prevent a train from derailing during an earthquake: https://www.rtri.or.jp/eng/rd/seika/2006/01/safety_E05.html https://www.rtri.or.jp/eng/rd/seika/2006/01/safety_E05.html
