Powered Rail

The Power rail is a block to be added in Version 1.5. They will replace bug boosting (boosters will still work after the update). It was tweeted by Jeb first to prepare texture pack makers where it will be. It will have 2 states, powered and unpowered. Power rails will most likely be crafted with gold and sticks.

Crafting
The recipe for power rails will most likely be six iron or gold ingots and a stick, similar to normal rails.
