Detector - Mob

The Detector - Mob 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 - Any will output a redstone signal if any Minecart is in front of it and is being ridden by an aggressive monster. 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.
