Minecraft wiki entry for Building_a_metropolis, associated text: Minecart: You can make a subway or overground railway to get people around. See Tutorials/Train Station for more information. Set up ticket booths and charge people, allowing them to drive the minecarts once they pay. An interesting tactic to try out, if you want to have actual trains, is to automate the fare collection process and make people drive trains. An even more interesting way to do this is to have two minecarts be pushed by a furnace minecart on and off of powered/unpowered rails to create a great and automated system. Plus, you get to brag that you have a use for furnace minecart.
