The train system in England is, in a word, crap. They don't come on time; when they do come, they are overfilled; the train stations are dangerous, smelly places... the list could go on.
So, my idea... BOUNCY TRAINS. I feel that they are brilliant. What happens is, the platforms are made of TRAMPOLINES. This saves time, as people can bounce along the platform and not miss their trains. To get onto the train, people jump extra hard on the platform and bounce onto the top of the train (which is open-top and soft) and then climb down the ladder into the proper part of the train. To get off the train, you simply jump off the top onto the bouncy platforms! Yes! What genius! Should it be implemented in Britain, I feel that a) a lot of money would be saved; b) a lot of time would be saved and c) people would be more eager to take the train because it is simply so much fun!!
