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. Using a Crowbar on it will cycle through its modes.

Coupling mode will link cart trains as they pass over, when provided with a redstone signal.

Decoupling mode will unlike cart trains as they pass over, when provided with a redstone signal.

Auto-coupling mode will link cart trains as they pass over, like coupling mode, but does not need any redstone signal to operate.

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