I saw a concept of a fying train somewhere in Asia. It was really amazing. When i saw it i thought about passenger drones. That concept of flying train can carry hundreds of passengers and will be good in crowded areas like cities but the train itself though it departs from the ground it is still connected to the rails. There is this connecting pole that connects train to rail so the train is not dislocated but always stay on its direction. I thought that if it was drone it wont have to be connected to anything in the land.
Im imagining, if it happens there will be abig change during rush hours wherein everyone is going to their workplaces. With passenger drones taking passengers in a maximum speed it could above the land, there will be no more falling in line in train stations, bus stations and heavy traffic.
