2 September 2005 - RSSB Risk Ranking Model
Report for July 2005 SPADS
Navigation
The new Risk-Ranking Model on Signals Passed at Danger (SPAD)
reports which provides information on Network Rail Controlled Infrastructure,
measuring the likely consequences as devised by Rail Safety and Standards Board
(RSSB), is now considered by the Health and Safety Executive (HSE) to be the
preferred method of reporting the monthly SPAD figures.
However, comparisons with the severity categorisation system are
at the moment included until the end of 2005, where thereafter the risk-ranking
model only will be used.
The summary report for July 2005 shows the following:
-
28 signals were passed at danger, 15 fewer than July 2004 and 10
fewer than the average for July since 2001.
-
July 2005 shows a figure of 10 less than the average figure for
July since 2001.
-
14 SPAD's were at signals with previous SPAD history, 5 of which
had been passed at danger 5 times or more since 1985.
-
5 trains ran past the signal by 200 yards or more.
-
11 trains ran past the signal by less than 25 yards or less.
-
7 instances showed it was not the first time the driver had
passed a signal at danger.
-
14 cases showed where the Train Protection and Warning System (TPWS)
operated successfully.
The above figures are interim and may change when investigations
are completed.
