Our franchise agreement does not obligate the franchisee to provide the information in the format requested by the member.

ScotRail provides my officials at Transport Scotland with statistical information on the public performance measurement (PPM), which is used in the railway system in Great Britain to provide a consistent and comparable assessment of performance. The PPM measure 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.

Performance information for ScotRail is available on-line, at the ORR Data Portal (Table 3.18). An on-line link to this table can be found here:

It includes ScotRail’s PPM information by operating sector and overall, on both a by-period and a moving-annual-average basis.

Also, ScotRail publishes quite detailed information for each four week period on‎ by-station and by-sector PPM. This information is published at stations, and is also available on-line, at this URL: .
