Question to the Department for Transport:

To ask the Secretary of State for Transport, how many and what proportion of services were operated with fewer carriages than planned on each route operated by each train operating company under DfT operator ownership in each of the last 18 months.

DFT Operator expects operators to provide appropriate capacity in response to expected demand and holds operators to account for short- formed services. DFT Operator generally monitors levels of short formations at an operator level every four weeks and therefore is not able to provide data for each route operated by each train operating company.
