What does it meany by the word signalling failure in the railways?

In railways, signalling failure means that the safety systems designed to control train movements are malfunctioning. Due to the malfunctioning, they cause a signal to show an incorrect indication (for example- a red light when it should be green) or for the system to not know if a section of track is clear). These errors force the trains to stop, thus leading to delays for the commuters. These failures are not usually connected with the signal itself being wrong. They can be rather a problem with the associated track circuits, axle counters, power supply, or points that detect train location or direct trains safely.
