Coupler Track

The Coupler Track is a special type of Minecart track from the Railcraft mod. This track is used to turn multiple carts into linked trains without the need of manual linking. This track will act as a normal track when it has a negative, or no redstone signal. When it has a positive redstone signal it will link all carts passing over it. You can turn this into a Decoupler Track by simply using a Crowbar on it.
