Question to the Department for Transport:

To ask His Majesty's Government how many passenger trains were cancelled due to the failure of staff to work on rest days for each of the last four weekends for which data are available, broken down by train operating company.

Train cancellations including those caused by a lack of available train crew are recorded by Network Rail and published by the Office of Rail and Road. However, the reason for the crew’s absence is not recorded. The Department works closely with its operators to secure improvements where they are not meeting expectations but does not routinely record cancellation data by day and cause.
