    Abstract - (Show below) - (Hide below)

    Applies to safety-related electronic systems (including subsystems and equipment) for railway signalling applications. Intended mainly to apply to "fail-safe" and "high-integrity" systems rather than medium or low-integrity systems or in marshalling yards where points are moved as vehicles approach.
