Question to the Department for Transport:

To ask the Secretary of State for Transport, what data her Department holds on the average number of carriages provided per service for each train operating company holding a National Rail contract in each of the last 18 months.

The Department does not hold data on the average number of carriages provided per service and has not carried out an assessment of regional variation in the proportion of rail services operated with fewer carriages than planned in the last 18 months. The Department expects all operators to run services at planned capacity where possible, and to mitigate the impact on passengers where services are disrupted.
