Signaling system of a railway organization provides the movement authority to the train drivers and therefore performs a safety-critical function. Various entities e.g. signal, train detectors (track circuit / axle counter), point, level crossing gates, sidings etc. are Interlocked to achieve safety.

This technique uses multiple failing runs in order to rank program statements according to likelihood of being faulty. However, the technique implicitly assumes that all considered failing runs fail due to the same error. In the event that multiple simultaneous errors are present in software, different failing runs may fail due to different errors,. This(More)
