P-coded cancellations

Operational statistics on resource availability shortage pre-cancellations are supplied to us from Network Rail and train operating companies on a periodic (4-weekly) basis. The dashboard, data table and historic factsheets present data for both on the day cancellations and resource availability shortage “P*-coded” pre-cancellations by cause for each operator. These include changes to train services caused by non-availability of staff or rolling stock that are included in a revised timetable, and therefore, may not be appearing in operators' cancellations scores.

The timeframe for publishing these on the data portal is driven by when we receive the data and also when any queries we have on the validity of data are resolved. Therefore, it can take up to 15 working days after period end for table 3128 to be updated. 

If you have any questions or feedback on these statistics, please contact rail.stats@orr.gov.uk

More passenger rail performance data on punctuality, reliability and causes of delay are available on our passenger rail performance page.

The factsheet previously published on a periodic basis was discontinued after April 2024 to March 2025 Rail Period 6.

Caledonian Sleeper have not submitted any p-coding data for April 2024 to March 2025 rail periods 7 and 8.
