Chinese puzzle over the train that never stops
The Chinese have a cunning plan to speed up travel times on their train network - make every journey non-stop. Shurely shome mishtake? Nope. It's only a concept design by a chap called Jianjun Chen, but it gets around the problem of trains having to slow down, stop, hang about, then set off again from stations:
Waiting passengers board an individual compartment on the platform - the passing train scoops it up, and in turn deposits another compartment with passengers wanting to alight form the train. Once the compartment is secure to the train, passengers can descend into the normal carriages for the rest of the journey. Mad as batshit.
