Double-decker Shinkansen & Double-decker Airliner (Jumbo Jet) & Double-decker Bus & Private Jet & HondaJet & Mach 5 JET. comment: Currently, the railroads are built on the ground, but all normal trains, bullet trains, linear motor cars, etc. should be elevated. It would be better to have all trains, Shinkansen, linear motor cars, etc. elevated. This way, there will be no car accidents. If they are suspended from the top, there will be no accidents involving people. It would be good to run double-decker monorails, double-decker bullet trains, and double-decker linear motor cars on elevated railroad tracks. Frequent automatic patrols on the tracks and robots traveling on the railroad just before the train or monorail runs would be safer because the brakes to avoid collisions would be applied in time. If ordinary trains, monorails, linear motor cars, and bullet trains all have a crumple structure like a soft cushion with a long nozzle at the end like the Shinkansen that lifts and pushes out people and cars even if they come into contact with cars or people and cause an accident, automatic braking will be applied quickly and safety will be enhanced. I think this is a good idea. If the ditch of the railway track is paved with highly durable concrete mixed with cellulose nanofibers on low-shrinkage concrete, instead of gravel near the platforms of stations where accidents are more likely to occur, it would be easier for people and cars to slide when they are in front of the train and come into contact with it.
