How do you make a fast moving mine cart track so you can get around your world quicker on Mine craft?

You use a powered rail instead of a regular one, and power it with redstone. This gives your minecart a boost. When you craft a powered rail, it's like crafting a regular rail, except you use gold instead of iron and put redstone below the stick. Crafting this way gives you 6 powered rails.

Note: Do not use all your powered rails at once, spread them out.
