The Dual-Head Block Signal is a block from the Railcraft mod. This block acts as a basic controller and a basic receiver combined, and is used in Railcraft signaling. It has two lights, the top one being a controller light, the bottom being a receiver light. These can be linked to other controllers or receivers by using a Signal Tuner and a Signal Block Surveyor.
