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 2013/14 compared with previous years.
Note: the figures reported in 2011/12 (277) and 2012/13 (252) have been amended following the downgrading of incidents that were originally categorised as SPaDs.
There were 293 Category A SPADs during the year compared with 249 last year, and the figure is above the four year average of 256. The MAA (normalised per thousand signals) is 0.64, which is 18.52% worse than the year end target of 0.54 and 4.92% worse than last year. Of the 293 Cat A SPADs, there were 22 instances where the train reached the fouling point (6 of the 22 signals involved were fitted with TPWS), the same number as the previous year (when 5 were fitted with TPWS), and three resulting in derailment compared with one in the previous year. We continue to work with rail industry colleagues to address and reduce risks leading to SPADs.
