A Chinese designer, Jianjun Chen, has come up with a creative idea to keep the ball rolling on China’s vast train network: alleviate the need for trains to stop.

The way it works is by using a nacelle, a small compartment that hovers above the track, to funnel passengers prior to the train’s arrival. As the train enters the station, the nacelle attaches to a specific point atop the train, where passengers can climb downstairs and enter their cabins. Only moments later, another nacelle located closer to the rear takes the place of the old nacelle, where passengers wishing to exit at that station can do so.
