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. Using a Crowbar on it will turn it into a decoupling track. A decoupling track will unlink cart trains as they pass over it, when given a positive redstone signal.

In Railcraft version 8.1.0.0 for Minecraft 1.6.4, the Decoupler Track was merged with the Coupler Track.
