The Block Signal is a part of Railcraft. For it to work, you will need a Signal Tuner and Signal Block Surveyor. You can create complex railways using these that also involve multiple minecarts or trains to pass through the same sections of track. By using Block Signals, Signal Block Relay Box, Signal Capacitor Box, Signal Controller Box, Signal Receiver Box, and the various Detectors, you can even make entire factories work around these.
