Directional Detector Track

The Directional Detector Track is a special type of Minecart track added by the Railcraft mod. This track is similar in functionality to the Detector Track. It will emit a redstone signal when a cart passes over it. This track will only emit a redstone signal if the cart is moving the same way as the arrow on the block. You can change the direction the track is facing by using a Crowbar on it.
