Detector - Advanced

The Detector - Advanced is a block from the Railcraft mod. This block is meant to output a redstone signal based on the type of Minecart that passes in front of it. The Detector - Advanced has a GUI in which you choose the Minecarts you wish to output a redstone signal with. They can be placed under or beside Minecart Tracks, and will output a signal to the side that has a small square. When a redstone signal is active this square will turn red.

Usage
Simply place the Minecart you wish to create a redstone signal in one of the nine slots in the GUI. This will create a ghost block, so your cart is not consumed.
