Minecraft wiki entry for Shelters, associated text: Make a long tunnel to fit from one to any amount of minecarts, then use minecarts with furnaces to propel the 'train'. You can also use powered rails, but for that you'll have to find gold and redstone. Be sure to add emergency chests to the side of the track and fill them with coal to power your minecart so you don't get stranded. Adding food and weapons in these chests is a good idea, in case you get stranded and have to fight some zombies to make it to your shelter. This is fun for multiplayer and single-player and you can go across the land quickly. Don't make your railway above ground; you will constantly be attacked by creepers. However, covering the railway with blocks (such as you would make a house) can solve this problem. Alternatively, you could build a 3 block wide track that is elevated off the ground 2-45 blocks. This option is very cool and provides great views but is not suitable for multiplayer. Make stations for your favorite landmarks (big mountains, your house, etc.).
