Question to the Department for Transport:

To ask Her Majesty's Government whether they will publish estimates of train delays caused by (1) infrastructure, (2) operators, and (3) any other causes, since 2017.

Estimates of delay minutes to train operating companies by responsibility and cause, are produced on a periodic basis (every four weeks) by the Office of Rail and Road (ORR). This data is available from ORR’s Table 3184, “Delay minutes by operator and cause (periodic)” and can be accessed from the ORR’s data portal.
