  • 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.

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

    Performance for 26 June - 23 July (Period 4)

    The national PPM is 87.4%.

    This compares to 89.4% for the same period last year.

    The moving annual average (MAA) is 88.4%.

    Performance 2002-2016

    Performance by train operator

    The table below shows the average PPM for Britain as a whole and by train operating company. The moving annual average is calculated over the 365 days to 23 July.

    Delay split by franchised operator

    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.
    • Britain's 24,000 trains per-day is also more than Spain, Switzerland, the Netherlands, Portugal and Norway combined.

    Franchise changes

    • Virgin Trains East Coast took over from East Coast on 1 March 2015.
    • For clarity we began to report Virgin Trains as Virgin Trains West Coast from 1 March 2015.
    • Caledonian Sleeper took over sleeper services from First ScotRail on 31 March 2015.
    • ScotRail took over from First ScotRail on 1 April 2015.
    • TfL Rail took over the London Liverpool Street to Shenfield metro services from Abellio Greater Anglia on 31 May 2015
    • London Overground took over the London Liverpool Street to Enfield Town/Cheshunt/Chingford services as well as the Romford to Upminster service from Abellio Greater Anglia on 31 May 2015
    • Govia Thameslink Railway took over the Southern franchise on 26 July 2015
    • First Great Western was rebranded Great Western Railway on 20 September 2015.

    A breakdown of each operator's performance, known as sub-operator PPM, is available to download:

    Cancellation and significant lateness (CaSL)

    A train is counted as being a CaSL failure if:

    • It is cancelled at origin.
    • It is cancelled en route.
    • The originating station is changed.
    • It fails to make a scheduled stop at a station.
    • It is significantly late (ie 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 23 July.

    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.

    Right-time performance

    Right-time is an unreliable measure of performance and particularly does not represent the results and experience of passengers serviced by long-distance operators who enjoy some of the very best passenger satisfaction levels in the industry.

    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 23 July.

    Delay split by franchised operator
     

    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 and fatalities which account for approximately one third of the delays attributed to us and 20% of all national delays.
    • Train operator caused to self: delays to a passenger train operating company's services that are caused by that company.
    • Caused by other train operators: delays to a passenger train operators services that are caused by another train company.

    The delay split was calculated over 365 days to 23 July.

  • 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.
