PolygamousRanchKid tips this article about an idea for revolutionizing the rail system in the long-term:
"The idea is to have a city-wide network of trams that travel in a loop and connect with a high-speed rail service. But instead of passengers having to get off the tram at a rail station and wait for the next HSR service to arrive, the moving tram would 'dock' with a moving train, allowing passengers to cross between tram and train without either vehicle ever stopping. 'The trams speed up and the high-speed train slows down and they join, so they dock at high speed,' explains Priestman. 'They stay docked for the same amount of time that it would stop at a station,' he adds. While Priestman admits that it will be some time before his vision could be implemented, he says the time has come to rethink how we travel. 'This idea is a far-future thought but wouldn't it be brilliant to just re-evaluate and just re-think the whole process?' he says."
