Signalling block system
A signalling block system (or block system) is a safety mechanism primarily found on railways that is used to prevent trains from colliding. Block systems divide the track into fixed segments ("blocks") using signals, sensors, or other equipment, and one train may occupy a block at a time. This ensures that a train always has time to stop before getting dangerously close to another train on the same line.
