P-coded cancellations

Operational data 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. This management information includes 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.

Official cancellations score is a weighted score which counts full cancellations as one and part cancellations as half. This industry measure is an indicator of disruption against the timetable operating on the day. The timetable is finalised at 22:00 the previous evening, and trains removed from the timetable before then will not be included. Adjusted cancellations score includes pre-cancellations (p-codes) due to resource availability, that may not be included in the official cancellations score.

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.

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