Signal Interlock Box

The Signal Interlock Box is a block from the Railcraft mod. This Signal Box is used to prevent conflicting cart movements in a junction or crossing. This is done by having more than one Interlock Box chained together, all linked to their own Signal Receiver Box and Signal Controller Box. When they are chained together, only one will be able to output a redstone signal at a time.
