A train in motion is a doing exactly what it’s supposed to do. Then why worry about stopping at stations?!
That is the (whacky)idea behind this concept train from China. Give the video given below a look to understand how it works: Passengers step onto a compartment platform above an incoming train, which is then snagged by the train as it moves through the platform. At the next station, anyone wanting to get off moves up into the compartment, which is then snagged by the station. The train itself never stops, it simply trades embarkation capsules as its moves through a station, giving passengers a window of time to board without the train needing to stop.
We are finally close to the standard of living made popular by The Jetsons.
