  • Category A Signals Passed At Danger (SPADs)

  • Definition

    This measure reports all Category A SPADs, which are instances where signals have been passed when a stop aspect, end of in-cab signalled movement authority, or indication (and any associated preceding cautionary indications) was displayed correctly and in sufficient time for the train to be stopped safely at the signal or end of in-cab movement authority. The table below shows the number of Category A SPADs for 2012/13 compared with previous years.

    Commentary

    There were 252 category A SPADs in 2012/13, compared to 277 in the previous year (adjusted from 278). The MAA (normalised per thousand signals) is 0.55, eight per cent better than the 2012/13 year end target of 0.60 and last year’s figure, also 0.60. We continue to work with rail industry colleagues to address and reduce risks leading to SPADs.
