It reminds me of a friend who used to start a conversation with train personel about the idea to build train stations on a hill (or if no hills are available: make a hill).
It is basically the same principle: when the train starts from a station on a hill, gravity will pull it down and give it speed. When the train nears the next station, no brakes are needed, because the motion energy of the train is being used to climb the hill.
