Question to the Department for Transport:
To ask the Secretary of State for Transport, if he will make it his policy to collate data on the number and proportion of train journeys that did not stop at a scheduled station due to late running in each train company in each year.
The Department has no plans to collate this data. The Office of Rail and Road, as independent regulator to the rail industry, records and publishes a range of information relating to the punctuality and reliability of rail services, including this dataset relating to cancellations: Table 3124 - Trains planned and cancellations by operator and cause (periodic) | ORR Data Portal.
