Detector - Powered

The Detector - Powered 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 - Powered will output a redstone signal if a Furnace Cart is in front of it. 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.
