Performance in the railway system in Great Britain is measured using the Public-Performance Measure (PPM), which counts all trains planned to run, which run and arrive within five minutes of their scheduled arrival time. Trains which are cancelled, either in full or in part, or which do not stop at stations at which they are meant to stop, are counted against this measure.
The lateness of ScotRail services is measured using the industry standard of the Public-Performance-Measure (PPM). In the year to early-December 2017 (period 9), 90.5 percent of trains arrived at Perth within the 5 minutes allowed under the PPM measure.
