Chinese transportation techies have developed a train that picks up and drops off passengers without ever stopping, by having travelers enter and exit a connector car that attaches and detaches from the train’s roof. It’s really ingenious and not so scary once you view the video demonstration. Because the train doesn’t ever stop, it saves time and fuel. The only thing I don’t get is how passengers can choose what stop they’d like if they’re in a car that automatically detaches. I’ll do some more research.
