Key Facts
The management, maintenance and operation of today's railway is based on the most modern techniques and technology.
In 2008/09, there were 35% fewer delay minutes across the system than 5 years ago
In 2008/09, 90.6% of trains ran on time - a new, all time record
In 2008/09, some £4.7bn was invested in renewing equipment and improving the rail system
In 2008/09 we spent £1.4bn improving train performance and increasing capacity
Last Period Performance
Our performance results demonstrate the improvements that we have made in the railway.
Overall Performance for Period 3 2010/11 (30 May 2010 – 26 June 2010)
Note: Latest information correct at time of publication.
Period 3 Public Performance Measure (PPM) Moving Annual Average (MAA) is at 91.5%, unchanged since last period and up 0.6 percentage points since Period 3 last year. Period 3 actual performance was 93.0%, down 0.1 percentage points on Period 3 last year.
PPM Results by period

PPM (ACTUAL) – 93.0% in Period 3 (30 May 2010 – 26 June 2010)

PPM (MAA) – 91.5% in Period 3 (30 May 2010 – 26 June 2010)

Breakdown of Overall Delay Minutes (MAA)

- The total number of industry delay minutes has reduced by 5.3% for the thirteen periods ending 26 June 2010, compared to the thirteen periods ending 27 June 2009. After adjusting for differing year lengths* delay minutes have decreased by 3.5%.
- Network Rail delay minutes in Period 3 were 463k, an increase of 2.5% on Period 3 last year.
- TOC-on-Self delay minutes in Period 3 were 234k, an increase of 2.3% on Period 3 last year.
- TOC-on-TOC delay minutes in Period 3 were 79k, a decrease of 14.1% on Period 3 last year.
* The thirteen periods ending in Period 3 2010/11 comprised 364 days versus 371 days for the thirteen periods ending in Period 3 2009/10.
PPM Methodology
PPM combines figures for punctuality and reliability into a single performance measure.
PPM measures the performance of individual trains advertised as passenger services against their planned timetable as agreed between the Operator and Network Rail at 2200 the night before.
PPM is therefore the percentage of trains ‘on time’ compared to the total number of trains planned.
A train is defined as ‘on time’ if it arrives within five minutes (i.e. 4 minutes 59 seconds or less) of the planned destination arrival time for London and South East or regional services, or 10 minutes (i.e. 9 minutes 59 seconds or less) for long distance services.
Where a train fails to run its entire planned route calling at all timetables stations it will count as a PPM failure.
Delay Minute Methodology
A delay minute is defined as a measure equating to one train being delayed for one minute when compared with the timetabled journey time between two points.
The main data set used for reporting both the TOCs and Network Rail delays is the Industry Period Performance Report (IPPR). However, IPPR sets all delays in dispute to the TOC. The purpose of developing the adjusted data series was to apportion the disputed delay minutes to the TOCs and Network Rail in line with a likely outcome of dispute resolution.
It is the adjusted data series that is used in the “Breakdown of Overall Delay Minutes (MAA) by Responsible Party” graph shown above.
