Powered Rail

The Power rail will be added in Version 1.5. They will replace bug boosting.

It was tweeted by Jeb first to prepare texture pack makers where it will be.

It will have 2 states, powered and unpowered.

Jeb also tweeted about a Detector Rail. Which will act as a pressure plate combined with a minecart track, a normal pressure plate would slow the minecart but it will keep going over the detector rail.
