A boat left on a railroad track does not usually disturb the train. The fast train on its track is a very heavy object with a lot of speed. This penny is simply too simple to do anything more. It is spread out or taken off the road by train. The basic premise of the work is energy conservation. Low-intensity objects (light slow moving objects) cannot do much of heavy objects because they have less pressure to give something else. That is why dust particles do not knock on motorcycles, ducks do not move in the sea, and mosquitoes do not divert trucks. Flat pens using trains are still dangerous; to people who put pens. Newspaper investigations revealed a number of cases of penniless who failed to disrupt trains but succeeded in finding those who put pennies on the process. Trains are invincible anyway. A car, a truck, or a brick left on the track can lead to damage.
