The percentage of trains arriving on time or within ten minutes of schedule is recorded as the ‘Public Performance Measure’ (PPM). The information requested is outlined in the following table:
Railway period start PPM (actual) (percentage) PPM (MAA) (percentage) Previous year PPM MAA (percentage) Change in MAA since 2008 23 August 2009 87.9 88.6 85.2 Improvement 20 September 2009 91.5 88.6 85.5 Improvement 18 October 2009 87.9 89.0 85.4 Improvement 15 November 2009 85.2 88.9 85.5 Improvement 13 December 2009 67.4 87.5 85.7 Improvement
Due to the severe weather the monthly PPM figure for the period starting December 2009 is considerably lower than for the period starting in November 2009.
Because of seasonal variations in performance, a more useful indicator of long-term trends is the Moving Annual Average—which is simply the average over the last 12 months.
The Department for Transport was not involved in this decision. Management decisions such as this are made by East Coast.
This is an operational matter for East Coast.
