  • Performance

    The number of trains that arrive on time has risen dramatically since we took over the running of Britain's railway in October 2002

  • Public performance measure

    The public performance measure (PPM) shows the percentage of trains which arrive at their terminating station on time.

    PPM combines figures for punctuality and reliability into a single performance measure. It is the industry standard measurement of performance.

    Network Rail caused delays: as well as infrastructure faults this figure includes external factors such as weather, trespass, vandalism, cable theft etc which account for approximately one third of the delays attributed to us and 20% of all national delays.

    Performance for 1 February to 28 February 2015 (period 12)

    The national PPM is 90.7%.

    This compares to 87.2% for the same period last year.

    The moving annual average (MAA) is 89.7%.

    Notes:

    • The measure of train punctuality also known as PPM (public performance measure) means trains arriving at their terminating station within five minutes for commuter services and within 10 minutes for long distance services.
    • This measure of punctuality is commonly used throughout Europe.
    • National train punctuality is measured for all trains across the whole network, including cancelled services and delays caused by external factors (such as vandalism, extreme weather, suicides etc).
    • Punctuality was not recorded in this thorough way until 1997. Before then Railtrack, and British Rail before that, did not measure all services and also excluded external factors and other items from their numbers.
    • These figures represent provisional data for the period and individual operators' performance data may vary slightly from the full period performance report that we publishes on our website every month.
    • Network Rail and the train operators run more trains across Great Britain than are run in most European countries - almost 20% more than in France and 60% more than in Italy.
    • Great Britain's 24,000 trains per-day is also more than Spain, Switzerland, the Netherlands, Portugal and Norway combined.

    Right-time performance

    Right-time performance measures the percentage of trains arriving at their terminating station early or within 59 seconds of schedule. The process for gathering data of this accuracy is currently not 100% reliable and the industry is working on improving the quality of this information to make right-time data more reliable.

    The moving annual average is calculated over 365 days to 28 February 2015.

    Cancellation and significant lateness (CaSL)

    A train is counted as being cancelled if:

    • It is cancelled at origin
    • It is cancelled en route
    • The originating station is changed
    • It is diverted

    A train is counted as being significantly late if it arrives at its terminating station 30 minutes or more late.

    CaSL is not a regulated measure for Scottish train operators.

    The moving annual average is calculated over 365 days to 28 February 2015.

    Average lateness

    This measures the average lateness of a passenger as they alight from their train.

    For each train, this is calculated by multiplying the number of passengers expected to alight at main stations by the punctuality to the nearest minute at those stops.

    If the train is cancelled, we calculate it by multiplying the number of expected passengers by 1.5 times the service frequency on that route.

    Delay split

    The delay split shows who was responsible for passenger train delays of 3 minutes or more.

    • Network Rail caused delays: as well as infrastructure faults this figure includes external factors such as weather, trespass, vandalism, cable theft etc which account for approximately one third of the delays attributed to us and 20% of all national delays
    • TOC on self delays: these are delays to a passenger train operating company's (TOC) services that are caused by that company
    • TOC on TOC delays: these are delays to a passenger train operators services that are caused by another TOC

    The delay split was calculated over 365 days to 28 February 2015.

    How punctuality is measured

    PPM measures the performance of individual trains advertised as passenger services against their planned timetable as agreed between the operator and Network Rail at 22:00 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 at the destination within five minutes (ie 4 minutes 59 seconds or less) of the planned arrival time for London and South East or regional services, or 10 minutes (ie 9 minutes 59 seconds or less) for long distance services.

    Where a train fails to run its entire planned route calling at all timetabled stations it will count as a PPM failure.
